Wireless supervision cameras are basically a closed-circuit television camera used for audio output transmission and video to wireless recipients who work on certain radio bands. It gets popular because it's compact. It doesn't need a broad video cable. It has simple installation equipment. There are two variations of wireless surveillance cameras.

Analog versions use radio frequency for audio and video transmissions that include a lined line of around 90 meters. This is more affordable. There may be some recipients for one camera. However, this is vulnerable to interference from household gadgets such as cordless handsets, microwave ovens, video game controllers, and routers.
