Great Cameras, Easy to Install

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.

Overall is ok.

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

2nd system

this is my second Defender system, the first being the 2k wireless. the difference between these two so far is night and day. a little more work to set up but worth it. down the road i'll be replacing the 2k system with another of these 4k nvr systems. hoping to have a video review up on youtube soon

2 systems installed - happy customers!

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.
