PROGRAMMABLE VOX BUG SPY LISTENING DEVICE 3V UHF WITH VOCAL ACTIVATION, VERSION VOX31A

Vox31A is a listening device, for bugging and spying from distance. This device uses the UHF band and can be programmable to many frequencies. The default frequency is 433.9 MHz.

This device uses a microprocessor and  high stability
As well, this bugging device uses an automatic switch, that switches it on and off depending on the audio level. For example,  during quiet , it turns off. If it hears speech within 4-7 meters from it, it turns on, and begins transmitting. This way, the battery lifetime is very extended, and this device may work for a prolonged time. The output is 20mW, and it uses a very short antenna. It uses a small 3V lithium battery, named CR2450.
The frequency is programmed, and cannot be modified by the user. However, upon request, we can program it to almost any frequency.
The VOX31S transmits a very powerful, clear sound.
