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 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!

This is my second set of defender cameras. My first set I got over 10 years ago and I was really pleased with them so I decided to upgrade and get the newest version. This 4K system is absolutely amazing. The quality of the photos, the video, and my favorite part of it all is the motion sensors that I get alerts for directly to my phone. I strongly recommend anyone in the market for a great security camera system defender is the one.

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.

The daytime images are crystal clear and detailed. The night vision is very good close to the house but a bit blurry farther away. That's the same as most other systems. The motion detectors are very sensitive. We had a good laugh because the alarm would go off for our backyard saying a human was detected. It ended up being our smoker with the cover flapping in the wind. After moving it a little, everything was fine. The app works well and you can handle most of the NVR functionality from it. The only thing we miss is 2-way sound cameras. We would have used those in place of the 2 pointing at our doors. We would recommend this system to anyone wanting good day & night coverage for your home or business.

I bought this system 3 months ago and have enjoyed using it. The image is very clear and the 24/7 recording is great to capture any activities. The ability to zoom and audio are great features.

Have had the system for a month or so and has done a good job recording. It is supposed to have sound, but I have not been able to hear any on video playback (may have missed a setting tho) Perfect for my outbuildings.

It’s works really well, we have 4 cameras and all of them working without interruption since 3 months. Night coverage is clear and even the sound records without interruption. In short you won’t be regret by selecting

Overall is a good system but it’s a bit cheap material and they can make it better. Included cables could be longer.
