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.
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.
Verified PurchaseI 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!)
Verified PurchaseLet 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.
Verified PurchaseIn 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.
Verified PurchaseWorks good ones set up right. Time will tell how durable it is. When install, Pay attention to the type of chime you have. I couldn't make it to work correctly with digital chime but it's works perfectly with mechanical chime. Also the ezviz app didn't works well and I switched to the hik- connect app which works right away. Nelly's tech support was helpful over the email. This is a good buy and I'm definitely recommend
Verified PurchaseI 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.
Verified PurchaseThe 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.
Verified PurchaseVery 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.
