There are 2 kinds of wireless video signals, analog & digital. Analog refers to a RF(Radio Frequency). Only FCC approved RF video signals for consumers are 5.4GHz, 2.4GHz & 900 MHz (obsolete). RF video signal can be interfered by other wireless products in same frequency such as cordless phones and wireless routers. Level of interference varies depending on the proximity of the camera to the receiver and the interfering source. There may be no noticeable distortion in video to slight ~ heavy horizontal lines in video. On the other hand, digital wireless or wi-fi have no interference at all.
