The IMF-3 multifunctional imitator is designed to imitate operating eavesdropping devices during search activities.

The device reproduces physical environment, that accompanies the process of the data leakage via the channels listed below, and allows to evaluate their characteristics.

Acoustic channel
- Vent channels, transparent slits, cracks and other acoustic openings, building constructions and technical service facilities
- Microphone effect of different equipment

Signals transmission via power supply network and telephone lines
- Imitation of suspicious signals in wire circuits.

Radio channel
- Imitation of operating eavesdropping devices.

Infrared channel
- Imitation of optical emission by lighting facilities, indicators, alarm sensors.

Telephone channel
- Imitation of a telephone tapping device, the data is transmitted via radio channel.
