Abstract

PROBLEM TO BE SOLVED: To simplify wiring by reproducing a video and voice on a home television receiver by radiating VHF radio waves based on a video signal and a speech signal outputted from a television camera and a microphone. SOLUTION: A human body detection element 1 senses a human body to make a transmitter 3 input a detection signal S1 and to make an alarm speaker 8 alarm. The transmitter 3 radiates VHF radio waves E1 based on the video signal S3 from the television camera 2 and the speech signal S13 from the microphone 18. A person in a room confirms the human body approaching the door of the dwelling by the alarm of the alarm speaker 8 and turns on the power source of the home television receiver 4. Radiated radio waves E1 are received by a VHF antenna 5 so that a video photographed by the television camera 2 is projected on the home television receiver 4 and voice collected by the microphone 18 is reproduced.
