Limited range and seems to be sensitive to interference, like from home wi-fi plus microwave. Picture quality pretty good for the price but figure on having the receiver close to the cameras.
Anyway the newer CCD security cameras with at least 520 TV lines are much clearer, cleaner, and work better at night. bucks, and it is worthless to me. I experienced constant signal loss, and wireless camera was within 15 feet Line of Sight of receiver. This item cost me $[.]. I could change my opinion, if there is a secret to making them work properly.
The manual is awash with "do nots" - keeping you from placing the cameras or the receiver anywhere near other electrical devices. Swann has a good reputation, and I don't know if any competitive setup would perform any better, but these wireless cameras are much too sensitive to radio frequency interference to be utilized in any electronically populated area.Even with the option to tune down below the frequency of common wifi channels, I guess my cameras were still being bombarded with other frequencies - possibly from wireless phones and such. These may work beautifully for surveillance in a more sterile environment, but I had awful luck with them.
If you have wirless internet were you plan to install the cameras you may experience interference as I did.My Client I installed this for was pleased. Good value for the price. (We had minor interference from wireless internet)
It is completely user friendly with wonderful picture quality. This camera duo is absolutely fantastic. and the night vision is exceptional.
