Just what we needed, and works as advertised. Easy or installation and good quality

I'm very happy with my system. It has clear images and the night images are amazing.

excellent - easy to set up and works great. I recommend......

Easy to set up. Need more details on how to configure software.

Fantastic security system for monitoring our manufacturing facility. Installation was easy and the cameras have a simple, yet robust UI. Would recommend to anyone looking for a simple yet effective security system.

We had 2, 16 camera systems installed in our business. They replaced our older system. The installation of the cameras was quite simple and the set up took little time. From a security perspective, we are pleased with the high quality of the video/feed and in reviewing past recordings, we found it easy to go back and find specific dates for review. Over the years we have had three systems and following our research, we are certainly pleased with the Sentinel Defender camera systems.

We bought this system to replace an older wireless defender system. The cameras are great and so much clearer and the night vision is so easy to see everything. I also like that the color comes on when the lights are activated. Playback is very easy to use. Set up was very easy. I highly recommend this system.

We've used Defender systems for many years and run a number of their systems and devices. We recently updated to the Defender 4K Sentinel POE system and pleased to have done so! The setup was simple, well documented, great image quality, ease of updates and love the functionality coupled with the Defender Empower App, that we use on both IOS and Android devices.

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.

The Sentinel system is exactly what I have been looking for! We loved the easy set up with 1 cable for footage and power! We didn't have to worry about power adapters or power bars. The great 4k resolution with motion detection is awesome! I have 1 camera in the backyard to check what critters that may be running by after the winter thaw!
