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

The SET UHF VOX8 combines the miniaturization and power of the UHF VOX8 transmitter, encased in ABS enclosure and the Hi-Tech of UHF-433 PLL receiver Ver. 1.
The VOX8 most important function of this surveillance bug is the voice activation, i.e. it transmits only whilst it hears voices. In the course of quiet time, while no person is at home or throughout napping time, it turns to standby mode, and it draws definitely less than 1mA from the battery. It uses a 9V battery.

When a conversation needs to be intercepted, and it is unknown when the conversation will begin, it makes sense using a voice activated transmitter, also called VOX. The advantage of voice activation is that you do not draw current from the batteries as a simple room transmitter for a prolonged time. The advantage using our voice activated transmitters is a built-in delay before shutting off, so that if there is a pause when your targets are speaking, the system will wait before changing the status to a standby mode.

We are adjusting each set to a 100% matching frequency. This set is using only high grade components, and one of the unique receiver features is listening to the conversation and recording at the same time, if it is connected to a recorder.
The PLL UHF CRYSTAL CONTROLLED RECEIVER can be used in a room or business, indoor or outdoor. It employs a high sensitivity circuit which allows the user to pick up RF NFM Transmitters from 200m in urban areas and up to 600+ meters (Line Of Sight).
