When a conversation needs to be intercepted, and you do not know when the conversation will start, it makes sense to use a voice activated transmitter. The benefit of voice activation is that you do not risk losing power to the batteries of a room transmitter that may be on for hours.
RF surveillance is secretive with the calculator transmitter, consisting of working radio frequency transmitter built into a functioning desktop calculator.
The calculator works as usual and nothing unusual can be found. It transmits conversations to a distant receiver with crystal clarity. The built-in transmitter is powered by the own batteries. Voice activation system makes the battery lifetime very long. Exceptional audio quality.
The voice activated calculator transmitter does not have any differences from the conventional calculator from the store because this listening device does not have any external switch, in contrast to similar products that are distributed in the market. This bugging device can be left on a table or counter, and moved from room to room, operating freely in an office environment where no one would suspect a calculator is housing a radio frequency transmitter.
This covert audio mini transmitter has two operating modes: work with voice activation and operation of the non-voice activated as a normal transmitter. Switching between the two modes by using the buttons calculator secret key sequence.
Our bugging device has its own battery and will not discharge the primary battery.
