Security Cameras

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

Picture quality is fantastic and the playback feature is great to have. Easy to get setup and started. Only issue is Human detection and Motion detection can be off sometimes with weather.

Good system, needs some upgrades

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.

24/7 recording with very clear images

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.

Human detection

Really good system compared to my older defender system. Image quality is good and the app is easy to use. Like the human detection feature!

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.
