Have you been putting off adding a camera security system to your home or business because you don't want to deal with bulky, heavy cameras or running numerous wires? With the Mini-Air Watch Wireless Color Camera Kit, you can put a tiny camera anywhere and transmit a vivid color video feed with audio directly to your TV or VCR so you can monitor what's happening in and around your home or business. The Mini-Air Watch Wireless Color Camera Kit is a tiny wireless security color camera system for homes or small businesses. It comes with a tiny, powerful wireless video camera and video receiver. You'll enjoy high-quality picture and sound transmitting and receiving from up to 100 feet away indoors or 300 feet away with clear line of sight. AC adapters are included for both the receiver and camera, but the camera can be operated with the included 9-volt battery for up to three hours of temporary use. The Mini-Air Watch Wireless Cameras connect wirelessly to specific channels, so you can maintain up to four cameras in your home if they send signals to different channels. This camera sends its signal to Channel 1; cameras for Channel 2, Channel 3 and Channel 4 are sold separately. It doesn't matter which channel camera you install, as long as homes with mutliple cameras maintain them on different channels. For an expanded system, the Mini-Air Watch4 comes with four cameras that connect to a single receiver.
