ABSTRACT:
A wireless video and audio transmission device is provided that comprises a transmitter, a receiver and a TV. The transmitter has a 2.4 GHz transmission module that modulates the video signals, audio signals from a microphone that have been amplified by the amplifying circuit, and signals from a detector The transmitter transmits those signals from a 2.4 GHz transmission antenna, and after reception by the receiver, the signals will be demodulated and processed into regular A/V signals. The A/V signals are coupled to the TV, and the detected signals are coupled to a buzzer to sound an alarm. A UHF transmitter of the receiver modulates the audio signals from a microphone that have been amplified by an amplifying circuit, and transmits them from a UHF transmission antenna. After the signals have been received by a UHF reception antenna, they are transmitted to a UHF reception circuit to be demodulated, amplified and processed into regular audio signals The audio signals are output to a speaker.
