Live Audio Transmitters

This collection features miniature Ultra High Frequency (UHF) surveillance devices that can broadcast real-time audio of their surroundings for extended periods of time. Surveillance transmitters can be received using any radio capable of tuning into the UHF/VHF band.

All Transmitters have been upgraded with revised PCB's and components that allow them to operate with greater performance. Most notably, we are now using gallium arsenide junction semi-conductors, to provide more range than any other UHF transmitter in the world. Moreover, the "aluminum-can" crystals have been swapped with a new state of the art glass-sealed ceramic crystal that offers superior performance in harsh environments and extended range, the antennas have been replaced with a new Alpha Wire micro-coaxial 38AWG whip, an upgradeable Knowles ultra-sensitive microphone has also been added to all transmitters. These changes and improvements are based on valuable feedback from our clients and have allowed us to offer a series of products much more suited for the environments they are being deployed in.
