SET PLL UHF SENSITIVE RECEIVER STABILIZED AND VOX8 VOICE ACIVATED BUG EAVESDROPPING TRANSMITTER QUARTZ CRYSTAL STABILIZED

The UHF VOX8 SET combines the voice activated powerful listening device transmitter VOX8, and the professional UHF-433 PLL receiver Ver. 1.

The VOX8 main feature is the voice activation, i.e. it is automatically activated by voice. During silence, when nobody is at home or during sleeping time, it turns to standby mode, and it draws less than 1mA from the battery. The bugging device uses a 9V battery and encased in an ABS box.

Transmits from 200m in urban areas and up to 600+ meters Line Of Sight.
We adjust each set to a 100% exact frequency. This set is using only superior quality components, and one of the unique receiver's features is listening to the converation and recording at the same time, obviously if it is connected to a recorder.

The PLL UHF crystal stabilized receiver can be used in a room,  office or business, indoor or outdoor. It contains a high sensitivity circuit which allows the user to listen from distance, wireless.
