For agent protection the DRT ( Digital Room Transmitter ) is the optimum solution. The risk of interception and detection during a critical surveillance operation will be reduced to its minimum because of the Delta-Modulation with digital covering. Signals coming from the DRT with integrated microphone can be received by a special appropriate receiver with digital decoder only. This transmitter can be equipped with an additional miniature mains adapter for permanent operation as well as remote control for individual on/off switching.
