Positive Customer Reviews and Comments

This is my second 8-camera Sentinel Defender system that I have purchased. This unit is much improved over their older model. Cameras are good resolution, recording time is great, setup is very easy, installation in a drop-ceiling environment is no problem.
-- G.L.

This system is highly recommended...DVR is awesome, and so is the camera picture quality. Definitely worth buying.
-- J.C.

I've had this system installed for 4 months now and it's been great.  The image quality is outstanding.  Love the peace of mind of knowing I have every on DVR in case something happens. 
-- J.T.

Negative Customer Reviews and Comments

Overall, this system gets very good reviews, but we were able to locate a few negative comments. The most common complaint is in regards to the cameras performance in sun or bright lights.

I purchased this video alarm system because I needed the e-mail alerts.  Despite what the ad says, there is no email feature. 
-- D.W.

The quality of the camera image resolution makes it tough to clearly identify individuals or license plates from much more than 10 feet away.
