The VOX25 is a very powerful bugging and spying device transmitter, using the UHF-band.


This professional covert spying bug, transmits clear and powerful sounds to a distant receiver, also programmed to the same frequency (not included), and the main features of this micro transmitter is the vocal activation and the micro size, and as it uses a single battery type "button", you can to hide it in any place. The original design allows you even to conceal it in many places, and due to the robust manufacture it will continue working.

VOX, voical activation, is a very useful feature. The spying micro transmitter doesn't have to transmit when no one is at home, during sleeping or when no one is speaking near it. It is a waste of battery power.
Therefore, the hidden microphone is not transmitting during silence, however just when it will hear a voice, audio sound etc., it will switch to transmitting mode. This way it has a longer battery lifetime, and at the same time, it is undetectable during the silence.

The hidden listening device, bugging spy VOX, uses a precise microprocessor, programmed by us, in our modern lab.
