The One-Wire Combo Surveillance System consists of a wireless induction loop, wireless keychain push-to-talk (PTT) and an EMI shielded covert earpiece. What makes this system unique is unlike conventional covert systems, the induction loop transmits the speech signal coming from a two-way radio on a much higher frequency than the usual plain base-band audio frequencies. The wireless earpiece picks up these frequencies and transposes them down to the audible domain again using a very powerful Digital Signal Processing (DSP) chip that carries out complex tasks such as automatic gain control, loudness limiting and soft squelch rapidly and efficiently. By transmitting on much higher frequencies, the covert communication system is immune to electromagnetic interferes. This process prevents stronger electromagnetic interferences to create a humming or masking sound within the earpiece. In other words: you'll own the only covert communication solution with EMI shield. The result is a clearer signal to the immediate ear, in a discreet "non-visible" communication system, even for the very complex Tetra and Tetrapol professional radios.
