An Audio/Video Transmitter & Receiver System is the use of devices to transmit a signal to a specific place, limited set of receiver devices (monitors or recorders).
A transmitter is an electronic device which, usually with the aid of an antenna, propagates a signal.
A receiver is an electronic device that receives its input data, uses filters to separate a wanted signal from all other signals picked up by antenna, amplifies it to a level suitable for further processing and finally converts through demodulation and decoding the signal into a form usable for the consumer, such as sounds, pictures and digital data.
This system is often used for surveillance in areas that may need monitoring.
The increasing use of A/V Transmitter Systems in public places has caused a debate over public surveillance versus privacy.
People can also buy consumer Remote Control Systems for personal, private or commercial use.
An A/V Transmitter & Receiver System is the best solution: there is simply no better way to monitor your home or business operations and ensure safety.
Hidden and wireless systems can be used in a variety of covert applications.
