Description
Electronic listening device is a kind of professional listening equipment which uses radio frequency technology to detect the suspicious mechanical displacement device in the target area.Electronic listening device can detect electronic pointer timing detonators and mechanical timing detonators hidden under various packaging coverings.Electronic detonating devices include timing detonating devices made of electronic watches, pagers and various remote control devices.It can also be used as an anti-reconnaissance security technology to detect electronic eavesdropping devices and covert video devices.It has the characteristics of high sensitivity, long detection distance, strong ability to penetrate the packaging cover, and easy to carry and use.
Features
1. High positioning accuracy: the product adopts radio frequency listening detection technology, with the characteristics of high precision positioning;
2. Low noise: using the built-in non-destructive sound detection technology and noise elimination technology, realistic restoration of the original sound;
3. Human-computer interaction intuitive: LCD display sound waveform, external speakers;
4. Open-use: simple operation, boot available;
5. Long standby time: low power consumption, the equipment can be used for a long time;
6. Safety no radiation: meet the national electromagnetic radiation safety requirements, absolutely safe for human body.
