DESCRIPTION

POWERFUL UHF VOX PROGRAMMABLE TRANSMITTER, LISTENING DEVICE, VOICE ACTIVATED, QUARTZ CRYSTAL STABILIZED, 3V


A VOX is a listening device which transmits voice wireless to a compatible receiver. Unlike simple bugs, it transmits only while there is a voice close by. During silence it stops transmitting and switches to standby.

The UHF transmitter transmits on the UHF band and the output is approximately 70mW  (in 50 Ohms antenna). It uses the most modern programmable micro-controller for excellent performance.
Highest distance may be achieved - Over 3.5 km range, line of sight (examined with ICOM IC-R6 and our special receiver PETRU433 ).

VOX characteristics:
The standard problems with many other bugs are short battery lifetime and the low output power.
This listening device extends battery lifetime, as during silence, the transmitter remains in standby mode.
On standby, it draws less than 1 mA. However, when its sensitive microphone hears a voice, it switches to transmission mode.
The accepted batteries:

1. 2 x AAA Alkaline (default).
2. Upon request, custom layout, 2 x AA Alkaline batteries.
If the usage of 1250mAh batteries - in transmit mode (non-stop transmission) the battery lasts for approximately 24 hours, and in standby mode, approximately 960 hours or forty days!

It is terrific for room surveillance, baby listening, nature studies, and so on.
The Estimated distance: Over 3.5km or greater in open area, line of sight (examined using ICOM IC-R6 and PETRU433 receivers).
Frequency is constant and cannot be modified. However, upon request, we are able to program it to almost countless distinctive frequencies.

This bug spy transmitter is designed especially for locations in which the reception is difficult,  as crowded areas or ground level areas. The VOX30 Transmits a  very powerful, clear sound. The transmitter is designed and tested in our specialized laboratory and tested as well "in real conditions" for maximal distance.
Our compatible receiver:
