The GEM NGD-100 is a digital encrypted miniature audio transmission system. It's 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 GEM NGD-100 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; 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 GEM NGD-100 provides excellent transmission quality, making them the ideal choice for body-worn applications, close protection monitoring and temporary deployments.
