VT-811 Enhanced Non-linear Junction Detector - Advanced Security and Privacy Protection

Product Overview

The VT-811 Enhanced Non-linear Junction Detector is an advanced security device that integrates wireless signal detection capabilities. It can detect hidden electronic eavesdropping and surveillance devices in packages, walls, floors, ceilings, lamps, furniture, or containers. The VT-811 can alert via sound or vibration and simultaneously use its wireless signal detection unit to quickly capture signals being transmitted and received, indicating the location of suspicious electronic devices on the screen. This effectively improves the efficiency of security checks and protects the privacy and security of businesses and individuals.

Technical Principle

The device transmits a fundamental frequency in the S-band while receiving second and third harmonic frequencies generated by the target object. Artificial intelligence algorithms analyze these harmonic patterns to identify whether there are suspicious electronic products within the detection area. Additionally, differential detection principles are used to exclude interference from distant signal sources, enabling effective detection of nearby suspicious wireless signals.

Application Scenarios

· Corporate Commercial Secret Protection: Detect unauthorized electronic devices hidden in important meeting rooms or confidential offices, such as eavesdropping devices, mobile phones, and devices containing SIM cards.

· Public Security and SWAT Bomb Disposal: Detect electronic detonation devices and remote controls in dangerous areas.

· Personal Privacy Protection: Detect hidden audio and video recording devices in residential areas, hotels, etc., such as voice recorders and cameras.
