This is our professional selection of audio spying bugging devices and transmitters. They use a very high sensitivity minuscule microphone and a powerful extended uhf transmitter. Once concealing these spying devices, they will monitor the entire room conversations, performing a crystal clear clarity audio.
The distance differs in urban areas and line of sight areas, without obstacles. The broadcasted audio can be received with one of our matching UHF receivers. The audio is crystal clear and can be recorded on most recording systems for further use. No further adjustments are required, just connect the device to the supply (battery, mains 110-220V etc.), and it will begin to transmit!! Then you may listen from a remote location to the room conversation.
