Digital Remote Controlled Audio Transmitter STRC-400


STRC-400 STRC-400 is a digital encrypted remote controlled audio transmission system. The digital transmitter with increased output power is designed to transmit acoustic data via radio channel with digital encoding.

Due to its tiny size the transmitter can be concealed in various items. The STRC-400 transmitter is suitable for the most miniature types of camouflage, making it an indispensable intelligence gathering tool for nearly every scenario.

Transmitted signal can be received by the high quality communications receiver with built-in decoder only (STV-02); the detection of the audio transmitter is extremely difficult. Due to the modulation process interception without a special decoder is very difficult.

The low power consumption enables excellent long-term audio monitoring operations. The STRC-400 provides excellent transmission quality, making them the ideal choice for body-worn applications, close protection monitoring and temporary deployments.
