Analog Digital Audio Transmitters Receivers
Our range of digital and analog audio transmitters are designed for covert audio surveillance in premises. They transmit high quality audio data via radio frequency Each tramitter has its own unique transmission freqency which allows multiple transmitters to be used in the same vacinity. The operator can selectively choose which transmitter he wishes to monitor using our dedicated Universal Receiver Recorder which has a unique built in high quality digital recorder. Our digital transmitter offer the user a much higher quality transmission reception, the signals are coded which means it can only be received by our dedicated Universal Receiver. they also offer a very secure transmission environment.
