PRODUCT INTRODUCTION
The MDAJ-PB-AT808 Electronic Listening Device uses wireless RF technology to detect suspicious mechanical displacement devices in target areas. It can detect hidden electronic pointer timers and mechanical timers under various packaging materials, including explosive devices made from electronic watches, pagers, and remote controls. It supports local and remote listening functions, enabling drone and robot-assisted distortion-free remote listening. This is crucial for remote examination of explosive detonation devices during security checks.
High Positioning Accuracy
Uses RF acoustic detection to penetrate different media and locate hidden objects with high precision and acoustic sensitivity.
Noise Cancellation
Built-in lossless sound detection and noise elimination technologies ensure clear audio transmission.
Weather Resistance
Features IP67 protection, maintaining functionality in rain, snow and extreme conditions.
Distortion-Free Remote Listening
Wireless transmission system allows operation beyond cable length limits, compatible with drones and robots.
Intuitive Interface
LCD display converts sound signals to visual waveforms showing frequency, intensity and dynamics.
Broad Application Range
Suitable for security checks in public safety, anti-terror, military, airports, stations and ports.
