VT-808 Electronic Audio Detector

Overview The VT-808 Electronic Audio Detector is a professional audio detection device that utilizes wireless radio frequency technology to detect suspicious mechanical movements in target areas. It is capable of detecting electronic and mechanical timer detonation devices hidden under various packaging materials. The device can identify electronic detonators made from items such as digital watches, pagers, and other remote control devices. It supports both local and remote audio listening functions, allowing it to be used with drones and robots for remote, distortion-free audio detection, which is particularly useful for remotely inspecting suspicious devices in high-security operations scenarios. Additionally, the electronic audio detector can also be used as a counter-surveillance tool to detect electronic eavesdropping devices and hidden video recording devices. It features high sensitivity, long detection range, strong penetration through packaging materials, and is easy to carry and use. Key Features

• National Production:Fully domestically produced with proprietary intellectual property, not subject to import restrictions from foreign technologies. Uses self-developed nonlinear harmonic detection technology and detection algorithms for enhanced security.
• High Precision Localization:Utilizes RF audio detection technology for precise localization.
• Remote Distortion-Free Listening:Supports remote distortion-free listening when used in conjunction with drones or robots.
• Low Noise:Incorporates built-in lossless sound detection and noise reduction technologies for realistic sound reproduction.
• Long Standby Time:Low power consumption enables the device to operate for up to 20 hours.
• High Reliability:Supports an IP65 protection rating.

Main Applications

• Essential equipment for high-security operations and professional safety checks, widely used by security personnel, anti-terrorism units, government facilities, airports, stations, ports, and other security inspection venues.
