Are you tired of your everyday, run-of-the-mill video doorbell? It can be difficult to find a doorbell security camera without paying expensive monthly fees for limited storage. But we have the solution! With the NSC-DB2, you can take control over your camera and its storage.

Use this doorbell as a standalone device with the slot for a microSD card. Enjoy up to 128 GB of onboard storage. Or you can add this to pretty much any NVR via the ONVIF protocol.

With the EZVIZ mobile application, enjoy quick and simple setup, push notifications, remote access, instant playback, and much more. Anytime someone rings your doorbell, you’ll get a notification sent straight to your device. Answer the door with the push of a button and communicate with your visitor with the full duplex 2-way audio.

With the PIR true motion detection, this doorbell won’t blow up your phone with false motion alarms. Neither drifting leaves nor shifting shadows will trigger the PIR alarm. The PIR sensitivity is adjustable, too. With these safeguards in place, you’ll only receive the notifications you care about.

Unsure how to install a video doorbell? The NSC-DB2 uses the wiring already present in your current doorbell. It’s instantly compatible with all mechanical chimes and most digital chimes. This makes the installation process a breeze. Plus, the doorbell comes with all the tools and hardware you’ll need.

3MP Resolution

The NSC-DB2 shoots video at 3MP @ 30 FPS. This is one step above FHD (Full High Definition) resolution, or 1080p. With this camera, you’ll be able to stream and record footage with 2048x1536 pixels, which will give you a picture that’s crisper and clearer than your standard high definition camera.

2.2mm Fixed Lens

The NSC-DB2 has a 2.2mm Fixed Lens. That means it’s fixed at one length; it can't optically zoom in and out. The longer the focal length on a fixed lens camera, the more zoomed in it is and the more close-up detail you'll be able to see. But the shorter the focal length, the wider the field of view and the more area your surveillance will cover.

The NSC-DB2 has a fixed length of 2.2mm, giving it a horizontal field of view of 105°.

Wifi Security Camera

Ditch the long, obtrusive wires running across your floorboards and walls. The NSC-DB2 allows you to connect wirelessly to your network using Wifi to capture and record video. Wifi security cameras are often easier to install, and they give you greater flexibility for placement and mobility.

IP65 Weatherproof Rating

This camera has an Ingress Protection (IP) rating of 65. This means the camera is completely protected from dust and other solid particles (the first six). It can also withstand streams of water jets from any direction (the five).

Rest assured that when you install your camera outside, it will have no problem withstanding the elements.

16' Night Vision IR Range

When the sun goes down or the lights go out, this camera switches on its own onboard infrared LED lights. These lights, which are invisible to the human eye, allow the camera to continue functioning and recording video 24/7, day or night. And since its IR range covers up to 16 feet, you're not going to miss anything that happens on your camera's feeds, even if it happens in pitch-black darkness.

  1. Great Doorbell!
    Verified Purchase
    I just replaced my Ring doorbell with one of these. Boy am I glad I did. Not only does it have a great picture, but you have a lot more control over your settings like motion sensitivity. It works a lot better than my old one. Plus I was able to get it to record on my Lorex NVR! All of this and no yearly fee! I have an old mechanical door bell and a 16 volt, 10 VA transformer and every thing works like it should.

  3. Affordable Video Doorbell
    Verified Purchase
    We have been installing these Video Doorbells for a few months now. The DB2 is packed with features such as PIR motion detection, Night Vision, 2-way Audio, notification schedule settings and more. The customers love that it comes with 3 Face Plates. As the installer, we love that it comes with the different style mounts at not additional charge.
    The setup is pretty straight forward. We stopped recommending the EZVIZ app due to missed doorbell calls the app was not loading quick enough. We switched customers over to the Guarding Vision App and it has resolved those issues. The PIR has been great and there are very few false positives. If you know what you are doing installation is a breeze. I see a lot of reviews of customers stating the doorbell did not stay on, it almost is always related to your homes transformer so be sure to check that voltage first. With the assistance of Nelly's excellent support, we were able to add the customers doorbell to the NVR for additional viewing. We have installed these in residential T and business setting. The customers love that there are no monthly storage fees!

  4. Won't stay connected
    Verified Purchase
    My first doorbell wouldn't stay connected more than 24 hours. I sent it back and tried a second doorbell. No better. Still won't stay connected more than 24 hours. I have a 24v 40 VA transformer and my router is 10 feet from the doorbell.

    I have a different security camera connected to the same network. That one is rock solid.

    When it works, it works great, but the connection is too unreliable.

    I will ask them for a third doorbell.

  5. Works Great, Once you do the firmware upgrade
    Verified Purchase
    I got a couple of these for my front and side doors. I have a 24 VAC, 40 VA transformer that operates both of the units with with no problem. My house has three mechanical chimes and my NSC-DB2's can operate the front and back door chimes with no issues. If you have a weenie 16 VAC bell transformer, you might want to upgrade it first.

    Installation and setup was trouble free. However, the doorbells continually disconnected and would eventually stay off line. The Guarding Vision App (recommended by Nelly's in the instructions) indicated that no newer firmware was available. However, there is a newer version on the Nelly's website, together with Batch Config Tool required to install it. (The doorbells don't have a web interface, so you need an App to adjust settings and Batch Config to update the FW.) Nelly's tech support was timely and very helpful. (Hint: Do the FW upgrade BEFORE you finish installation and screw on the front plate. You may have to do a hardware reset after the upgrade!) Once I did the upgrade, the WiFi connection has been rock solid on both units.

    The devices can't be set with a static IP (as of FW rev: V5.2.4_190625 anyway), so you may want to set a reserved IP in your LAN's DHCP server to ensure that each device is always issued the same IP address. (Essential if you want to use ONVIF.)

    It was then a simple matter to add the two doorbells to my Synology Surveillance Station system as ONVIF devices. And the Synology properly detects PIR motion from the doorbells so you can record either full time or only when motion is detected.

    The built in PIR motion detector is quite reliable and not nearly as subject to false alarms as video image motion detection. The area specific PIR sensitivity settings are a nice touch. Image quality is very good, although it would be perfect if they could do hardware pincushion correction. But that's asking a lot from a doorbell.

    All in all, a really nice device with all of the features I was looking for. (ONVIF, PIR, 3MP, mechanical chime control, and no monthly subscriptions!)

  6. Sketchy start
    Verified Purchase
    Let me preface by stating I've only had the camera doorbell installed for 4 days. I'm hopeful these early issues will sort themselves out over time. I'm impressed by the video quality and up til today the response time as well (more on that later). The first day of installing Guarding Vision app was challenging and a bit confusing. I must have reset the camera at least 10 times before the error messages stopped and it finally connected. I can't explain why it wouldn't connect since nothing was changed from the first attempt to the last successful one other then checking if the doorbell (mechanical chime actually was working without the app). Note: it was not! The final attempt was trying to use the AP Mode for Wi-Fi configuration, located on the last page of the manual. Oddly this is not possible as described and defaults to the normal installation procedure which went straight through without further issue. Of note is the change of proprietary viewer applications EZVID to Guarding Vision. Can't compare the two so not sure if this is an upgrade or just a licensing dispute. Today, 4 days after installation, someone rang the doorbell and I was through with the caller before the app acknowledged someone came to the door a full 3 minutes earlier. Restarted my phone just in case no improvement, then cut the power to the camera for 30 seconds then the camera and app work perfectly again. Hopefully this isn't a regular occurrence or I might have to ask for warranty relief. Based on the other reviews your experience may vary. Having spent some time comparing Nelly's version of this particular camera doorbell hardware (there are a few) I still believe they have the best combination of features this hardware can support. Thx for reading and I hope you'll consider this version in spite of these initial hiccups.

  7. Finally got it to work
    Verified Purchase
    In my earlier review I cataloged the issues I was having with this doorbell camera. I have subsequently resolved these issues. The primary problem was frequent disconnects on a daily basis. I had to do two things to get my system to work: First I replaced an ancient low powered transformer with a new 24V/40VA transformer. My voltage at the doorbell button went from 11 or 11.5V to 25V. I immediately noticed faster response time But I still experienced disconnects. Less often than before but still unacceptable. I woke up every morning to find that my doorbell had gone “offline” overnight. Finally I updated to the newest firmware version. Presto! Everything works fine now. No more disconnects.

  9. Great when it works
    Verified Purchase
    I purchased this doorbell several weeks ago. It has been nothing but a headache for me. I can't tell you how many hours I've spent trying to troubleshoot this thing.

    When it works it is great! Wonderful video and overall good features. Unfortunately for me, it only works intermittently. After 4-8 hrs. I begin to get "unstable network" messages when I try to connect with the EZVIZ app. Then eventually the camera goes "offline". I've checked my home network carefully. I have a very powerful wifi signal at the doorbell installation site. My router tells me I have a -50dBm connection to the doorbell. I have tried both 2.4GHz and 5GHz bands with the same results. Nelly tech support has been sympathetic but offer no solution other than to purchase another doorbell to see if I might have a defective unit. Even when the doorbell is working properly and my router indicates a great connection to it (-50dBm), the wifi signal strength indicator in EZVIZ "Settings" shows only one bar of strength. The doorbell seems to "think" that its connection to my network is weak when it is actually very strong.

  10. Best Doorbell Camera available if you know how to set it up
    Verified Purchase
    The NSC-DB2 is the best video doorbell available, period. First, it has Full HD video, as opposed to Ring's 1080p. The storage loops on an SD card (up to 128GB) that saves money on the cloud. Consider if you had a doorbell for 5 years, you'd be paying anywhere from $300 to $600. For doorbell security camera coverage... The SD card on the NSC-DB2 can be accessed by phone or tablet or pc emulator. Next, the motion sensors are very good, they pick up the zones they are supposed to and no more, this was also not my experience with ring. The unit is also waterproof and works with mechanical chimes (an indoor existing chime) which is not available from other video doorbells. The wifi chimes are not something I wanted as I don't like the look and I read many users having reliability issues (wifi connection, power issues, etc). I feel like a mechanical chime that is hard wired is the best looking and most reliable option.

    It would be impossible to find all these features in any other doorbell to date. I only have a couple complaints but didn't take off a star for them as they are not really the fault of the doorbell. First, for some reason, the doorbell is advertised as running on 8 volt - 24 volt transformer, and Nelly's Security recommends higher. I don't know what to say other than this is just false advertising. This doorbell does not run reliably on an 8v transformer. I have a short run from my doorbell to the transformer, and the 8v transformer I had gave extremely spotty coverage, many disconnects, etc. If something only works sporadically, it doesn't work. I feel the advertisement should be changed to REQUIRES (not recommends) 16v 30VA (voltage amp) transformer or a 24v 30VA or 24v 40VA transformer or nothing at all. I don't feel it's a good idea to mislead people to think it's possible to use less. If you're not going to change the advertising material, make a week long video with the doorbell working and not going down for the entire week on an 8 volt transformer and post it, which I am guess wont' happen as it would be impossible. Also the name of the doorbell (NSC-DB2) is very awkward. I changed the transformer and everything works great now, I just wanted to give a full review of everything for anyone wondering as this doorbell seems to have solved all the issues the previous generation (NSC-DB1) had and then some.

How do I confirm if I have enough minimum voltage needed to see if I will need a transformer or not. I do have a multimeter, just need steps on how to use. If I need transformer, please share the link also.
Thanks
Hello,

You will need to measure the voltage at the Installation location of the DB2 itself.
It needs to be 8-24VAC.

Here's the transformer we recommend - https://www.amazon.com/gp/product/B019BW9VZ2/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1&tag=ipctk-20
Hi-

Hi-

In the set up instructions, you suggest using the Guarding Vision app. In the video tutorial you suggest using the EZVIZ app.

I suppose each may have specific advantages over the other. Briefly, could you please summarize the pros and cons of each and your overall recommendation as to which to use?

Thank you!
Hello,

So the Guarding Vision app and the EZVIZ app are both very similar. However we primary recommend the Guarding Vision app as it seems to be the most universal app with the best options for controlling settings. As well as performance on both Android and iOS devices which is why we updated most of our guides to include it. Please see our guides located here - https://support.nellyssecurity.com/hc/en-us/categories/360002599194-NSC-DB2 for more specific instructions regarding the setup of your DB2.
(1) IMO, The fatal flaw with the older NSC-DB1 (other than the night vision) was that if you pressed the button and no one responded, the doorbell spoke up and said "there is no one to take your call", which to me was tantamount to it saying "go ahead and break in". The only way around that was to reduce the speaker volume to zero, in which case you could no longer speak through the doorbell either. Does the NSC-DB2 have this behavior?

(2) Can the camera be configured without the app? How do I know my wifi password doesn't wind up on a server in China?
(1) The DB2 does not have this issue. BTW, the latest firmare on the DB1 removes that message.

(2) It definetely needs the app to be configured. This doorbell doesnt even have a web interface. All data is password protected. Your P2P account is protected and then your actual doorbell is password protected as well. From my understanding, all USA networked devices are passed through Amazon AWS servers.
How do I connect this camera to a 16 channel Hikvision NVR?
Hey David,

Once you have the DB2 added to your local network. It will have an IP address. You can find that using the SADP Tool or Batch Config Tool.
You will use that IP address and manually add it to the NVR that is connected to the same network.

The username will be "admin" and the password is typically the 6 letter verification code that is unique to your doorbell.
Can it text alert multiple people.
Hello,

Yes it can! If everyone is signed into the main Cloud account on the App, you will get the full notification features across the multiple devices.

Does this doorbell only record to NVR after motion detection? Or must it continuously record? Currently I have a Dahua NVR that works well with EyeSurv cameras set to record via motion only.
Hello,

The DB2 will only record continuous when it is added on an NVR.
Since you have a Dahua, you will have to add the DB2 using the ONVIF protocol.
How do I connect this to my NVR? Default user/pass?
Hello,

Here's the default login credentials for the DB2:

username - admin
password - Verification code

*The verification code is on both the usermanual of the DB2 and on the backside of the DB2 itself.
Password example - ABCDEF
Is this the same as/ a re-branded RCA Video Doorbell HSDB2A?
It appears to be made by the same manufacturer but likely comes with a different firmware than ours. Our firmware is specifcially made for onvif compliance.
If I connect this to an NVR via ONVIF, can I still use "the app" to answer the door and have a two way conversation with someone at the door?
Hey Kyle,

Yes, full functionality through the app is possible whether or not its connected to other devices.
I have three entrances to my house, so I need three door cameras. However in the pass I tried a similar door camera and it worked great. But when added a second the cameras didnt work as well. And I found was it was related to the door power supply was unable to handle two door camera. I'm sure your works great however will i be able to use three and if not what's solution to be able ensure I dont have the same problem before them.

Thank you
Hello,

We do like recommending to have each DB2 on its own separate circuit.
Powering all 3 on the same circuit may be difficult.

The required voltage for the DB2 is 8-24VAC.
Hi,
This is Jumah from Saudi Arabia.

I'm putting a video together so I can promote this camera to my customers. I am wondering (roughly) how much video time a 16GB card will hold vs. 128GB card. Looking online I haven't found a chart for 3 megapixel video and of course it varies with frame rate and compression. Any numbers you can provide?
Hello,

Typically the 16gb card can get you roughly 2-3 days of storage since its motion-based.
And depending on how busy the area around the camera is, with a 128gb card, you should get roughly a month.
What are the outside dimensions of the doorbell? The location of the current doorbell is very narrow and most of the other video doorbells are too wide.
Hello,

The DB2 is 1.81 inches wide, 5.12inches tall, and 0.83 inches deep
Will this connect to my Google home hub?
Hello,

We have not been able to test this sadly.
The EZVIZ app has IFTTT integration, but it has not been tested here.
Is it suitable in Europe ?
Hello,

We have had customers use this over in Europe.
You'll need to make sure you have the correct power requirements in the circuit though (8-24VAC).
When using this doorbell with mechanical chimes, do you have to add a "booster" to the chime itself or should it just work well as long as your transformer voltage is adequate? If you need a booster, are additional ones available to use with multiple chimes?
Great Question. The doorbell requires a booster, atleast thats what the instructions encourage. The good news is that the package includes one. Im not sure I would recommend wiring this with multiple chimes. Everytime we have had someone attempt to do that, they always had major problems.
If I plan on connecting this to a NVR, does it still require an SD card for local storage, or can the SD card be removed after initial setup?
The SD card is not needed after adding to an NVR.

However, if you like redundancy or if the NVR powers off, but the DB2 is still functioning. A SD card would be a nice option to have to continue recording just in case!
Hi,

I have four Hikvision bullet cams and using IVMS 4200 software. Can I add this doorbell camera to the IVMS 4200 (pc) and also use the EZVIZ app? Would I be better off to just migrate everything over to EZVIZ? I'm not currently recording any streams and don't have an NVR installed.

Thanks!
Hey Tim,

You can add it to ivms-4200 and still use the EZviz app to view it on your phone. The ivms-4200 software and EZVIZ mobile app are completely separate so migrating everything to EZVIZ would only take away your PC viewing ability. Adding all devices to both the mobile app and PC software should work fine.
Cann this doorbell be controlled by Alexa? How about Smart Phone?
Hello,

We have not been able to test with Alexa unfortunately.
However, you can experience the full features of the DB2 through the Guarding Vision app on your smart phone!
Hello, Can I sync/use electronic chimes with the NSC-DB2? I don't want to install a mechanical chime.
Can I use my Synology NAS for recording?
If it is a wireless electronic chime that will Not work, you can use a wired digital chime. The doorbell will work with Synology NAS (firmware update will be needed on the doorbell).
I connected the unit and its working fine with the EZVIZ app. What options do I have to see control the unit from a Mac?
Hello,

You have variety of options to access this product from a mac. We recommend that you use the Guarding Vision, Web Plugin or the IPC Web Plugin. If you go to the bottom of our product listing page you will see where we have linked These for your convenience under the downloads tab.

I can connect 2 video bell?
One front door and the other back door?
Hello Ugo,

You can connect two doorbells I would just recommend using a separate transformer rated at 16-24 volts/30 VAC for each unit.
What is the right transformer for this doorbell?

The spec says 8-24VAC, but the doorbell shuts down after an hour with my 10VAC transformer. I'm guessing 24v/30VA is the right amount of power for this doorbel and will try it tomorrow.
Hello,

A 10VAC is probably gonna be a little to low for that particular model we recommend 16V minimum but a 24V/30VA will ensure that there is ample power to the device.

If you have any more questions please feel free to reach out, thanks.
Does this work with 3rd gen Echo "Alexa"
You would need to disable stream encryption in the app. Once you do this it should work fine. You can get to this setting in the Guarding Vision app by clicking on your entry for the DB2. Then once you have the live view full screen click on the three dots in the upper right hand corner of the screen. Then clicking on the settings button if you scroll to the bottom of the screen you will see the Image and Video Encryption section.

1. What event or events initiate video recording? Motion, doorbell push, etc? How long the the recording continue and what dictates that it stop?
2. What is the audio delay time when duplex communication is in progress? Can you practically carry on a conversation with someone at the door?
1. If you have the alarm notification setting enabled this activates the PIR and motion detection for the DB2. We hope a future firmware update will solve this issue. It currently saves a small clip of video that stops about 5 seconds after motion has stopped. Pushing the DB2's button also saves a picture of who pushed the button.
2.The audio delay time will depend on various things primarily your network speed and how strong the internet connection is to your phone. You can carry on a conversation with someone who has pushed the button of the DB2. As long as the DB2 and your phone have a strong connection to the internet the lag is minimal.

Hello,

Unfortunately we do not have Avertx NVRs here to test with.
However, with the latest firmware on the DB2, it allows the support of ONVIF Profile S.

I would certainly reach out to Avertx to see if your NVR supports that specific profile version just to be safe!

I use an apple mac and I've downloaded the tools as suggested by this Q&A section; I also use synology surveillance station so getting the ONVIF working will be very important to me. Now that is out of the way I have a couple questions about the software and the setup of ONVIF using the BatchConfigTool (BCT) and the Guarding Vision app.

When I first set my DB2 up I could see it in the BCT app and when I tried to configure the doorbell for ONVIF it failed every time. I upgraded the firmware as suggested and still it failed to configure ONVIF. I rebooted my WAN and the BCT app no longer saw the device on my network. It took some digging and I eventually found it when I connected to my router to check the connected devices. I ended up downloading the Guarding Vision app so I can add a static IP so that when my router reboots I wont loose my doorbell camera.

Q1, Why does the BCT app not see my doorbell? I have to manually add it to the guarding vision app in order to see it and manipulate the settings?
Q2, Can I mute the ringtone when the doorbell is pressed? I don't really want anyone hearing that ringtone when someone pushed the doorbell button.
Q3, I've installed all the mac tools suggested on this page including the browser but when I click on the browser config icon in the guarding vision app it opens my browser but opens a blank screen. Is there something that I need to do in order to make this work so that i can configure the device settings that way?
Hi Ernest,

1. You don't need to enable ONVIF using the BCT, it's already enabled. You just need to add it to your synology. Not sure why it was showing up initially in BCT but isn't after a router reboot, you may try resetting the doorbell using the button and then reconfiguring it to your wifi.

2. Not at this time

3. No, the DB2 does not have a web interface so any configuration needs to be done using either Guarding Vision or BCT. If you have Guarding Vision working BCT isn't needed.
Is there a monthly fee to use this unit?
There is no monthly fee to use the NSC-DB2.
I can see that the NSC-DB2 comes with a "power kit". What does the power kit do exactly and if I already have a tri-volt transformer (8V/16V/24V AC 20-30 VA) currently hooked up to my existing mechanical door chime will I still need to install this power kit?
Hi, yes you will still need the power kit if you plan to use the doorbell with a chime. The power kit helps if the voltage isn't high enough for the devices such as with older transformers.
I am looking at the NSC-DB2 doorbell camera and have a couple of questions.

First, Can the NSC-DB2 Doorbell Camera send video clips and snapshots to an FTP server?

Second, the network my camera will be connected to does not have access to the internet. Will I be able to configure the Doorbell Camera while my phone is connected to that same network? Will the camera continue to send video to my NVR/FTP that is also on the same network as the camera (No internet access)?
To connect the NSC-DB2 to a network that does not have internet access you would use your computer we have a guide on that method located here - https://support.nellyssecurity.com/hc/en-us/articles/360043787034-How-to-setup-the-NSC-DB2-using-a-PC-Windows-.

To connect the NSC-DB2 to a NVR you would want to follow one of these two guides - https://support.nellyssecurity.com/hc/en-us/articles/360038889693-How-to-Add-Your-NSC-DB2-Video-Doorbell-to-an-H-Series-NVR or https://support.nellyssecurity.com/hc/en-us/articles/360038377294-How-to-Add-Your-NSC-DB2-Video-Doorbell-to-an-R-Series-NVR.

There is no built in method to connect the NSC-DB2 to a FTP server.

Can it connect to Echo 5 unit. So I could ask Electa who is at the door
The NSC-DB2 cannot currently connect to the Echo 5.
What is the largest SD card that can be used in this unit?
Hello,

You can put up to a 128gb MicroSd Card in it!
Hey guys... love this device.

Question/problem...

I currently have a reolink NVR and a few cameras... all is working well. However, I am NOT able to add the doorbell camera to my system.

It did pop up briefly, showed video, and i was able to access settings via my NVR, but overnight, it has dropped off the system. Seems no matter what I do, I can no longer get it to display via the nvr.

Works fine on its own with EZVIZ or other hickavision software.

Any suggestions to get it added back into my reolink nvr?

Thanx in advance.

Dave
Hello Dave,

What settings did you use to link the NSC-DB2 to your reolink NVR? I would add it via the onvif protocol with port 80 the password will be the verification code to the NSC-DB2. If you are still experiencing issues I would download the batch config tool and latest version of firmware from the product listing. Then upgrade it and re-add the device to the NVR.
I love the product and it works great. I'm using it on a Mac with SecuritySpy in addition to the iOS Guarding Vision app. In the camera's video feed, the format of the overlay date and time are "MM-DD-YYYY HH-MM-SS (S)". I have two questions: (1) Can I change the date format to "YYYY-MM-DD HH-MM-SS"? (2) What is the meaning of the "(S)" following the date and time? Thanks!
Hey Andy,

Glad to hear you like the Doorbell. You can definitely change the date format to YYYY-MM-DD using the batch config tool. The setting is located under Image->Video Display in the doorbell configuration.

The (S) means that the time and date are synced with a time server. If you turn off the time server the (S) goes away.
Does the NSC-DB2 (or the DB1) require an internet connection? Does the lack of an internet connection effect functionality of wifi functions? For example NVR storage, application alerts, etc?
It does require internet connection for full fucntionality
I have two doors on the front of my house. Will I be able to install two of these doorbells? I know 16v transformer is minimum for installing one and that is what I have now. Would I most likely have to install a 24v transformer for two?
You will actually need to install 2 different transformers. We have had issues with folks running 2 doorbells off of one transformer.
Hi,

I saw the unbox/install video and I really like your video doorbell. I have a question regarding the installation of the unit near the door. Our front door does not face the street so our bell is not installed on a part of the wall that faces out. Do you offer a mount that would allow the doorbell to be mounted with a 90° so it does face outward from our house?

If not, do you have any suggestions?

Thanks.
Hello,

Unfortunately there is not a 90degree mount for the DB2. We've seen plenty of customers use the slight horizontal wedge with it and have had great success.
don't have doorbell at door, so no wires ?
battery powered ?
Hello,

The Db2 is not battery powered, you do have to run 8-24VAC power to it.
Can you retrieve recently deleted notifications/files?
Hello,

If you delete the notifications, you can go back through the playback still to see the old footage, but if you format the SD card, all stored footage will not be retrievable.
This camera would be perfect, but my metal door frame (only option for mounting this) is 1.75" wide. Is there a place I can look at the components to see if I can make my own slightly smaller case out of milled aluminum? Thanks
Hello,

Unfortunately we do not have a picture of the internals of the DB2. However, from experience, the internals of the DB2 take up most of the same size as the enclosure.
Also, taking apart the DB2 will void the warranty too if something were to happen.
Does the app have a way to silence the door bell during baby naps, evening, etc?
I would like to use my existing "dumb" doorbell.
Hello,

Unfortunately there isnt an option for this.
The doorbell will ring the chime anytime the button is pressed.
I have other IP cameras that are connected to my NVR on a separate network via Ethernet cables. The NVR has another port for connecting to my wireless router which is on a different network than the one used to connect the IP cameras.

1) How would I connect the NSC-DB2 to my NVR?

2) Does the NSC-DB2 support multiple video stream on different networks? One stream for NVR recording, another for remote viewing via the gateway?

3) Can the 2 way interactive communication be configured for a different network as the stream used for NVR recording?
Hey Ken,

1. You add it like any other IP camera that's not being connected directly to the back. Most NVRs you simply go to Add camera and then input the IP address, protocol, port, username and password.

2. Yes you can record on the NVR and view remotely using the phone app.

3. I'm not sure what you mean, feel free to shoot us an email at customerservice@nellyssecurity.com with more details on this question.
I am looking for a video door bell for my parents. They live a long way off. I need to be able to show up install/setup door bell and have it work successfully. Mom has an I phone and a I Pad and would like to be able to answer on either device. I like that the device has internal and not on going cloud storage. So what apps are needed to make this set up possible on I phone and I pad? It would just be the two devices. My understanding it connects to the Wi Fi router and then connect to the Wi Fi connected device like I pad. The I phone not so sure?
Hello,

The app needed for the DB2 will be called Hik-Connect for both mobile phones and the iPad.
We have an awesome guide here on the setup - https://support.nellyssecurity.com/hc/en-us/articles/360038358514

You will basically sign into the same Cloud account across the different devices!

Youre correct. The DB2 connects to wifi, then it talks to the cloud servers, and thats where the phone and tablets view the DB2 from.
Does the unit record over the older clips when the micro sd card gets full, or would I have to format it every now an then?
it does recorder over the older clips.
Does the door bell work with any smart locks?
Hello,

It will not unfortunately. There are no terminals or integration for the DB2 for smart locks.
I've seen other doorbell cams that launch video while answering the doorbell along with 2-way audio. Does this NSC-DB2 cam have that capability and if so where can that be set as I just get a call for 2-way audio with a white screen and no video.
Hello,

We've seen this problem with the EZVIZ app here lately and have been recommending a different app called "Guarding Vision" as a fix.
You can log into the same cloud account and everything!
Can you change the view of the camera, from a fisheye view to other views?
Hello,

You cannot. The DB2 has a fisheye lens and it cannot be changed.
Do the installation holes that came with the Nelly video doorbell are compatible with the screw holes in the junction box in the concrete wall and which are used to hold the Video doorbell against the wall? I am talking about the junction box in which the old ring bell was installed.
Hello,

I would assume that they arent since these are completely different manufactured doorbells.
But if you'd like to email us the specs to the Ring bell, we can compare here.

Email us here - customerservice@nellyssecurity.com
Hello,

How many users are able to log-in to the doorbell system or get notified at one time or another time?

Example most homes have 2 phones at the very least, would the doorbell app support both phones using the app with the same QR code is scanned?
The limit on the Guarding Vision app is high enough that most people would not reach it. We typically have 5 people logged into the same account everyday and do not experience any issues. The easiest method if you are sharing the device with your spouse is to log into the same account using the same username and password. However you can also share the device with other people if they have their own Guarding Vision account. This is done in the app either through their phone number or email address.
Hello, are the doorbells available in the UK or could you tell me how much shipping would be to the UK.

thank you for your time.

Simon.
Hello,

We can ship the DB2 to the UK!
If you put your address in the shopping cart, you should get a shipping estimate.
Can you recommend a wifi chime / speaker that works with this system for a setting where a door chime does not currently exists? I want to use theDB2 system and also install a new compatible digital chime. Is there a plugin speaker / system (similar to the Ring speaker) that can connect via wifi (or in some other wireless fashion) and works / syncs with the DB2? Or is the only way to connect a hard wired chime? Thanks, -S.
Hello,

You can find all of the compatible chimes here -> https://www.screencast.com/t/AL2wETakd

However, none are wifi capable as the DB2 does not support wifi chimes.
From all the info I have gathered here I can use the EZVIZ app for the install set up and then the HIK- Connect app for operations across MAC devices or should one app be use for the whole process. I was going to play with the device before giving it to my parents but was not sure if I could get it registered once it had been set up. Once installed can it be moved and registered to someone else ie. when my parents move and I can take it? Is HIK- Connect Guarding Vision?
Hello,

We are now actually recommending the app "Guarding Vision" for the DB2 setup process.
Once you have the DB2 added to a cloud account, it will stay on that account until removed.
From there you can add it to a different account once its been removed.
What’s the wide size in inches?
Hello,

It is 1.81 inches wide.
I have a 24V transformer powering my doorbell. Can I use a 8V mechanical chime?
Hello,

I wouldnt recommend it. Theres a high possibility of over-volting your chime.
Id recommend getting a chime that supports 24V.
I'm looking for a doorbell camera with audio that connects via Ethernet cabling. Thanks.
Hello,

The NSC-DB2 does not have a RJ45 connection and we do not carry one that does at this time.
All the recommended chimes are rated 16VAC, but the transformer is 24VAC. Everything I am reading says that you should not use a 16VAC chime. Am I missing something here?

Hello,

You can certainly use a 16V 30VA transformer with the list of compatible chimes!
Does this truly have an “Enable Onvif” Protocol check box option to connect to allin1 Hybred DVRs
Hello,

The DB2 supports ONVIF profile S and will certainly connect to our tribrid DVRs, or other hybrids that support ONVIF profile S.
How do I change the IP Address to a static IP in a completely different network (not a 192.168.x.x)? Thanx.
Hello,

Firstly, you'll need to have the DB2 connected to a wifi network that has the subnet that you are wanting.
Or you can log into the router that the DB2 is connected to and lock its MAC address to a specific IP address that youd like.
Does the doorbell offer a battery back up to support when the power is off?
The Doorbell does Not have any battery backup option. The only work around would be to put the transformer on an external battery backup (UPS)
The doorbell does not have a built in backup battery option.
Do u have a list of compatible doorbell shimes?
Hello,

Yes, here's that list -

I have a Reolink RLN8-410-E NVR. Is this doorbell compatible to be able to record to this NVR?
Hello,

We've seen Reolink NVR's have trouble working with the DB2.
But every case is different! You are more than welcome to give it a shot. We have a hassle free 60-day return policy if it doesnt work for you.
How does this compare to the Hikvision DS-HD1? Specs look the same to me.
Hello,

The styles are different from what i can tell.
Our DB2 is more of an equivalent to the EZVIZ DB1
Does this work with Samsung Android phones?
Hello,

Yes it does. You will use the app called "Guarding VIsion" from the Google Play Store.
my doorbell is perpendicular to my front door. Is there a wedge provided for this type of angle?
Hello,

Yes the DB2 comes with 2 wedge mounts. One is a vertical and another is a horizontal wedge.
Can the DB-2 be streamed and recorded to a laptop?
Hello,

You can view the Db2 using the IVMS-4200 software.
If you'd like to record to the laptop however, you will need a 3rd party software such as Blue Iris to do so.

The DB2 does support up to a 128gb MicroSD card as well!
Does this product have its own chime wireless capability?
Where I would like to put this there is not currently a door bell.
Would I have to run wire from my mechanical chime to the new location as there is no door bell there now?
Hello,

The DB2 does not support Wireless Chimes
Yes, if you would like the DB2 to activate a chime, you would have to put the chime and the DB2 in the same circuit.
Do you offer instalation?
Hello,

We do not unfortunately.
If you'd like to reach out to our support team, we can see if we sell to an installer in your area though!
customerservice@nellyssecurity.com
Hello, The link you provided to the preferred transformer produces a menu of choices. Does it matter if I choose the 24V, 40VA model, (or any other model besides 16V 10VA), since you include a booster, which you suggest SHOULD be used?
Hello,

I like to suggest the 16V, 30VA transformer so it can push enough power to both the DB2 and the chime if you have one.
What is the physical dimensions specifically the width of the door bell unit?
Hello,

The DB2 is 1.81inches wide, 5.12inches tall and 0.83inches deep.
Which compression method you use. H.265, H.264
Which version of ONVIF is installed in the camera?
Can IR be disabled (door area is well lit) ?
Can it record color at night?
Hello,

-H.264 for the DB2
-Profile S
-It sure can, from within the app.
-If you disable IR, itll stay in color mode. But it does not have a low light lens like our NiteColor Cams.
Your company says that you can use this doorbell camera with a nvr but i have a dvr. Does it work with lorex's DVR system ?
Hello,

As long as your DVR supports ONVIF IP camera's, then you can certainly add the DB2 to it!
Can this also be used with Google Home hub
Hello,

We have not been able to test the DB2 with the Google Home Hub.

The DB2 does support a RTSP stream and the EZVIZ app has IFTTT support too. So you may be able to get some kind of integration going!
Hi can this doorbell camera work with Alexa ?
Hello,

We have not been able to test the DB2 with Alexa unfortunately.
I do know that the Db2 has an RTSP stream you may be able to integrate with IFTTT
Can it interface with a N.A.S. ?
Yes, it can be added to a NAS. We have tested it with success on a Synology NAS and have heard it works with other brands as well.
I have 2 doors that ring my mechanical door bell. I only want to use the NSC-DB2 on 1 of the doors. Do I need to unhook the second door to avoid problems. Really only use one of the doors anyway.
Thanks
Hello,

We typically recommend the DB2 to be on a single chime setup.
If thats possible to do and taking out the second chime, then great! Definitely do that.
My house never has had a doorbell, are you planning a battery powered unit with a bluetooth or wireless chime?
No plans to bring in a battery powered doorbell at this time. Keep checking back with us though!
Is this a real on if camera?
Can we connect it to any NVR
Hello,

The DB2 supports ONVIF profile S. It can be added to other 3rd party NVRs that supports that as well.
Does this doorbell allow you to turn your mechanical chime off similar to the google nest hello?
We don't carry the Nest Hello doorbell so we aren't familiar with it. However, you can definitely disable the connected chime using the app.
Can you save the live stream video to a networked hard drive? Or do i need a nvr to do that?
Hello,

If you have say a NAS on a local network with Synology Surveillance Station, you can add the Db2 to it and save footage there!
I'd like to notify Home Assistant when someone has pushed the doorbell button. I could do that if the doorbell sent an ONVIF trigger to Blue Iris, or if it could trigger a relay that I could connect to an alarm zone, or if it was integrated with IFTTT, or maybe something I haven't thought of. What is my best option?
Hello,

I know the EZVIZ app can integrate with IFTTT, but we have not tested it with any Home Assistants sadly.
Is it possible to use the NSC-DB2 with Ubuiti's Unifi Protect?
Hello,

If you are able to add ONVIF capable cameras to the UniFi Protect, then you should be able to!
We do not have that here to test unfortunately.
Is it compatible with google
At this time, it is not
Is there a way to verify if my NVR is compatible with this device?
Hello,

You should be able to check the spec sheet of your NVR to see if it supports the ONVIF protocol.
If you are unable to find that, possibly try reaching out to the manufacturer, and they should be able to tell you!
Does it have MQTT intergration? seem the only thing I see isn't on the spec sheet to get it intergrated into my home system.
DB2 does Not offer MQTT integration
Once the device is configured and connected to the WiFi, does it require an Internet connection to access a LAN based NVR?

Id like to block this device from access to the internet for security purposes and have it solely managed via local storage.
Yes it does require internet access to work properly. It uses a cloud p2p server to pass the notifications on to the app
Hi, can you ship it to Portugal?and dose it work in 220v?
Hello,

Yes we can!

The DB2 supports 8-24VAC, you will need some sort of transformer to step down the voltage.
Hi there is this doorbell compatible in Ireland?
Hello,

Good Question! If you can get 8-24VAC to the DB2, then you should be able to work with it.
Typically a transformer is needed to step down the voltage.
is it compatible with Amazon's Alexa?
Hello,

We have not been able to test Alexa capabilities yet with the DB2.
The EZVIZ app does have IFTTT available and the DB2 has an RTSP stream you may be able to integrate.

But as of right now, we havent been able to test this ourselves.
If I have an 8 channel R series DVR can I still add the doorbell even if I'm using all 8 channels? I know on some others you can?
Hello,

The r-series DVRs have the capability of adding additional IP cams on top of the analog cams it supports.
After a firmware update on the DB2, you will essentially take the DB2's IP address and assign it to one of the channels on the DVR using the ONVIF protocol
Hi, looking to buy 2 of the DB2. What NVR with ONVIF would you recommend?
Hello,

Since the DB2 is an H-series camera, i would recommend any of our H-series NVRs.
-1
This is onvif.... correct?
Yes the DB2 is ONVIF compliant with a firmware upgrade!
-1
Does this unit record 24/7 to SD card or only when motion is detected?
Hey Randy,

It records only when motion is detected. To get 24/7 recording you can add it to an NVR.
-1
I have LVT9708MHS NVR & network drive both connected to home wifi.
will i be able to transfer data from this doorbell directly to one or both live ? that way if its stolen; i do not need to worry about it.
You can transfer data to both simultaneously. However, I would probably recommend just streaming it to one device because we have seen issues sometimes when too many devices are pulling data from the stream at one time. Id probably just recommend streaming it to your NVR alone. This way you will have data both on the doorbell as well as the NVR for a backup.
-1
My door is about 20 feet from my router and the signal strength there is quite good. But the unit seems to drop connection from time to time and the only solution that I have been able to find is taking the cover off and resetting it. Is there a better way to tell it to reconnect to the network that doesn't require taking it apart? The unit itself doesn't seem to be very good and either maintaining connection or reconnecting by itself if dropped.
Hi Cheney,

I sent you a direct email.
-2
Can this be connected to LAN.

If yes, can it be POE?

Also, does it have an output for a door strike or other device like a relay?
Hey Eddy,

The DB2 can be connected to your LAN via WIFI.
It does not have PoE.

Also, It does not have an output for a strike or relay either.
