Very disapoinred with this product. Should have spent the extra $100 to get a better system. I've installed several CCTV systems...I hate myself for being so cheap and buying this system. The wires are very fragile...do not pull,even slightly just lay them in place. I handled them very carefully but still had several breaks per cable. I've installed several systems and have never had a wire break on installation. Night vision is a joke.....not even 30' has advertised. Also very choppy on remote viewing, delayed,and slightly blurred. I checked Woor's return policy..."only for defective products, not ones you are not happy with..........well I guess this comment will never see the light of day......DO NO T BUY!!!
