It consists of two vivid CMOS color cameras with night vision (B/W) and audio, and a compact 2-channel receiver with sharp 380 TV lines picture display output. The camera converts video and audio signals into radio signals and transmits them to the receiver, which then can be input into TV, VCR, or DVR for crystal clear sound and picture. Ideal for home or business.
