I have been using this sentinel camera set up for about a month now. The installation of the cameras was easy to do. It did take some time to hide all the wires, which is to be expected. The NVR was very simple to set up and I did it without any problems. The picture quality is amazing on a 4K tv. I had no issues with setting the app up either. The steps are very well layed out. The quality of the picture during the day is absolutely beautiful. There is an option to record with black and white, or colour, or in smart mode. It’s crazy how in smart mode when motion is detected at night, the scene gets lit up in colour and it is just as good as in the daytime. This was a nice surprise. For most of the camers I kept the sensitivity level on low. When turned up it will pick up rain and you will get a lot of notifications. Turning down the sensitivity helped with this issue. The cameras that are semi protected under an eve also help reduce false alerts. Just something to think about when doing the camera placement. I really like the app. It’s easy to find and play your motion alerts. It has a playback feature that you can watch all your alerts for each camera. After playing the first video, it jumps to the next one automatically. We’ve had problems with bears in our neighborhood, so I use the playback feature to view captured motion alerts that happen at night. Overall I have had a good experience with the defender 4K Sentinel security system. I highly recommend this system if you want or need a good quality system with the best quality of picture. It’s nice that the price doesn’t break the bank too!

Giving it 4 stars because it is a good system with nice quality cameras but: 1. It came with a faulty Cat5e cable, it has power but no connection is detected. 2. The human body alarm is faulty when camera is set on an angle, I have one installed at my porch area and it keeps thinking the tree or even my front door mat is a human body.. 3. The night vision light can be a bit annoying sometimes, I don't think I've found a promising solution to have it turned off completely or not that sensitive.

The Defender Alarm System is AWESOME!!! The cameras now clearly monitor our hallways. We previously had major issues with students running up & down our hallways. The cameras recorded very clear & distinct photos that were given to the local high school. Problem solved!! The pictures on the monitor alert our staff when there is activity in the office. We love our system and Our staff are feeling very secure & safe. Patient & staff safety are Our #1 concern. ‘Wish We had installed The Defender System before. It’s very user friendly & We can observe any movement from across the room. Recently the hydro was out (4hrs) the emergency lighting allowed Our office to carry on as usual. Less stress, NO more worries! Thank YOU Defenders!

Installed in a day and very happy with the video quality. I don't use any detections, it's something I'm still on the fence about but I'll probably work on setting it up soon. Also, there is a way to use the app on the computer though using the software Bluestacks, it's a phone emulator for your computer and it's free.

The whole system comes well packaged in the box. Everything is nice, clean, and tidy which you'll see is carried on in the whole system and software. Everything is quality and is as simple to set up as possible. The hardest part for me was running the cables through the attic and finding the best locations for the cameras (about 8 feet or slightly higher), but it was well worth doing. Everything else was easy. The cameras themselves are solid in construction, and they produce clear images day and night. They seriously blow my old wired 720p system out of the water and are superior to my wireless 2k cameras. In addition, they have sound. My children have been in a few minor fights with each other and the sound really helps put what happened into perspective. With the sound I actually know why the fight happened. Unlike my old wired system, there is only 1 Ethernet cord per camera that goes from the NVR into the attic and out to the camera. You won't need to run a separate power cable. I'm very happy with everything. I love knowing that I can access the cameras remotely on my phone and not just on the DVR. You'll hear and see everything you need to and you'll have the ability to eliminate false alarms such as leaves falling, birds flying by, dogs walking by, etc, and just detect humans.

My overall impression of the 8 Channel 4K Sentinel NVR is very good. The system came well packaged with each camera packaged in it's own box. It was a breeze to setup with the cameras truly being plug and play. The NVR and accompanying app were configured within 10 minutes of unboxing. By far the most difficulty is running your cables to your camera locations. Take your time and plan where you'd like your cameras and the routes you have access to for the cable runs! The image quality of the cameras is fantastic and far surpasses the wireless cameras I used previously. The accompanying app is intuitive and easy to use. I was surprised at how little bandwidth this system uses. There are many options which can be configured around motion detection, notifications and schedules. Setting up and using this system has been a great experience and has provided a lot of value in a nice DIY package.

So far the cameras and NVR are working great. Much better than my 2K system.

Really good support when I call in. The Sentinel system is working well and easy to install.

Great camera….just need access to desktop computer…

Great System for the money especially for a new business on a tight budget !
