Video quality is top-notch and worth every penny.  Installation was fast and easy.  I, along with everyone I've shown this system to, is super-impressed by its quality.
-- U.T.

Overall I like this camera system. DVR is great. Camera picture is good. You dont need anything but a monitor to make this system work.
-- J.H.

This is a great alarm system and it does exactly what is advertised.  The night vision range is good and we really like the pic on pic feature and search ability.
-- B.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.

My only complaint about this system is the cameras.  During very sunny days, it can be very difficult to see anything in the screen.  They need some kind of filter.
-- T.R.

The cameras work okay but the quality is bad in bright light. Considering I am located in a tropical country, this is not very good.
