Set transmitter with vocal activation VOX9, and programmable, high quality, sensitive receiver

Unique combination between the spying wireless transmitter, featuring voice activation, VOX9 and the programmable, sensitive UHF receiver Petru433.

The VOX transmitter is stabilized by a component named quartz crystal. It stabilizes the frequency, so even if touching the antenna, which is very short, the frequency remains steady. The Vocal Activation is very a very important feature. During the silence time, when nobody is at home, or during sleeping time, the UHF transmitter is not transmitting, therefore the current from the battery is almost zero. As soon as a sound is captured by the sensitive external microphone, the spying device is activated and transmits the audio, clear and powerful, to the receiver. The spy VOX transmitter has an adjustable trimmer, and the customer can adjust the sensitivity.

The receiver is one of the most sensitive UHF receivers you ca use, and due to this sensitivity, it almost doubles the distance compared to other receivers. This is a modified transceiver, and the receiving plate was replaced by our special design. It has a rechargeable battery, and the sound is exceptional.
