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. 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.

  2. Great
    Verified Purchase
    Very satisfied with this purchase.

    I had to settle for a non-POE doorbell camera and I'm glad I chose the NSC-DB2.
    I had to install a new transformer for my mechanical chime. I got a 24V/40VA and it works great.
    The system was easy to setup and install and there are plenty of videos online that help guide you through.

    I was able to connect it to my NVR by adding it manually, but the motion detection does not work. This is a bummer since it means I can only have scheduled/continuous recording through my NVR and not motion detection.

    The app works flawless so far. I don't know why it has such bad reviews. I have an iPhone X, it works great and it's quick. All of the motion detection and alerts work fine through the app, I just wish it would work on my NVR.

    Install was fairly straightforward and customer support was very quick and helpful. I had emailed them about my chime not working and it turns out my transformer was junk, was only getting 10V but you need minimum 16V. I got the 24V to have enough.

(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.
This is onvif.... correct?
Yes the DB2 is ONVIF compliant with a firmware upgrade!
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.
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.
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.
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!
Can it text alert multiple people.

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.

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.

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.
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.

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).
Can you please provide the dimensions of this product with the cover? If it is in the Specs and I overlooked it, I apologize.


According to the spec sheet, it is 5.12in x 1.82in x 0.85in

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?

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.

If you have any more questions feel free to reach out, thanks.
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.

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.
You answered a question on Aug 23, 1019 in this section: "Yes the DB2 is ONVIF compliant with a firmware upgrade!"
Where can I get the firmware upgrade and how can I install it?

We would provide you with it along with the tool needed to upgrade the firmware. The software is available for both Mac and Windows PC's.

If you have any other questions feel free to reach out, thanks.
Is the doorbell compatable with the Annke 3MP H.265+ DVR

If your DVR has the capability of adding an ONVIF IP camera, then yes it is!
You answered the question "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?" - however none of the Apple downloads under this unit's downloads page are working. I get 404s.

You should be able to view the DB2 using the "Guarding Vision" software link on the downloads tab.
If that is not working, i will email you a version of ivms for mac.

If you do have any other issues, i would suggest contacting the Support Team rather than the Q&A section.
The night vision feature on this, is it color or black and white ?
Thank you
It is black and white
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.

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.
Is this compatible with Google Assistant or Chromecast device? I would like to be able to go "Hey Google, show me the doorbell camera."
We have not tested the camera with either of those devices sadly. I do know the EZVIZ app has IFTTT support.
You may be able to integrate it with that!

Also, the DB2 does have an RTSP stream you can link it with.
How do I connect this to my NVR? Default user/pass?

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
From the app can you retrieve video that is stored on the SD card.

Yes you can! In the App under "my devices" at the top left corner, theres an icon that brings you to the playback section.

From there you can select the day&time and hit play!
Can you connect magnetic door lock to this ?
Unfortunately you cannot. The doorbell does Not have any kind of relays.
