This microphone transmitter is different from the other transmitters that we have, because it has the VOX function: it allows the battery saving because it only transmits when there is a sound activity in that area.

This transmitter is the only programmable spy bug microphone in the world ! It can be programmed on any frequency you wish from these: 430 – 439 MHz, 2.5 kHz channels step or 860-879 MHz with 5 kHz channels step.

You will need a transceiver (wide band receiving option) or a radio FM scanner in order to receive this UHF spy bug microphone transmitter. It will be placed in a hidden corner of a room, like under the bed, under a desk, inside a toy or other object, after the battery will be inserted in its place and it will capture the sounds in the room and transmit them to a UHF FM receiver, to a distance of up to 2,000 feet (in open field).
