The spread-spectrum digitally encrypted bug is a professional room audio bug transmitter which operates by using a totally encrypted RF transmission.

Without the provided matching receiver it is therefore impossible for any third party to listen to actual audio speech or transmission by simply tuning in on the transmitter frequency with an ordinary radio as well as scanner receiver.

Thanks to the fully encrypted RF transmission, this room audio monitoring system ensures ultimate confidentiality as well as an impressive, crystal-clear audio quality, by featuring a super hi-gain preamplified microphone on system transmitter and an extremely advanced A/D converted on receiver.

The FSK spread-spectrum modulation allows up to 8 different frequency slots, thus meaning that up to 8 different transmitters can be used within the same operating area and tuned by a single receiver for listening in digital quality.

A receiving station is also optionally available, allowing up to 8 different VFOs so that up to 8 different audio signals can be listened to and recorded all at the very same time without the need to continuously change channel.

Dedicated receiver features volume and on/off knob, channel selection button, power on LED, digital FSK signal coverage control LED, dedicated earphone plug and battery charger plug. Despite this is one of the most advanced and complex product in its field, we have succeeded in keeping it as easy as pie to use.

Featuring and unbeatable price for the product (price includes dedicated receiver), comes with all needed accessories, nothing extra to buy. Comes complete with:

1. portable receiver with earphone;
2. RF transmitter with preamplified microphone;
3. rechargeable battery pack;
4. battery charger (not in the picture).
