Powerful voice activated micro transmitter VOX30 and programmable receiver PTR433

Powerful set of spy bug programmable transmitter, voice activated VOX, and programmable sensitive receiver PTR433.

A VOX is a surveillance device which transmits the audio, wireless, to a remote receiver. During conversations or speaking time it will transmit a clear sound, as a commercial radio station. The VOX is programmable and we program it in our lab. We can program it to almost endless frequencies in the UHF band. Shortly, after a defined time, if it won't "hear" voices or sounds, it ill switch automatically to standby mode, and it will quit transmitting. If it will hear any sound again, it will switch to transmitting mode.

This way, it preservers the battery life for a very long time. 

The microphone is very sensitive. and will pick up a voice sound from approximately 5m (~ 16ft.). 

The receiver is designed by us. It is inserted in a transceiver and replaces the original transceiver's receiver. This receiver competes the best expensive receivers in the market, programmable and sensitive. It uses a short antenna, and it is rechargeable.
