VS-810 Nonlinear Junction Detector

VS-810 Nonlinear Junction Detector

The VS-810 Nonlinear Junction Detector, independently researched, developed and manufactured by SZ Vodasafe, is a top-tier domestic security inspection device built on proprietary harmonic detection technology and high-precision phase algorithms. It delivers non-destructive all-scanning capability to precisely locate hidden electronic devices concealed inside packages, walls, floors, ceilings, lamps, furniture and various containers.

This detector can detect and identify all semiconductor junctions as well as rusted metal junctions. It is fully functional against electronic equipment with semiconductor components, whether the devices are powered on or completely shut down. When semiconductor-based electronics or rusted metal junctions are detected, the unit triggers integrated visual, audio and vibration alerts for clear operator notification.

Tailored for confidential information protection and indoor security screening, the VS-810 is especially effective at hunting powered-off electronic wiretapping and hidden pinhole camera recording devices, making it an indispensable tool for anti-eavesdropping and anti-spying confidential space sweeps.

Main Application Scenarios

Public security, military, customs and enterprise confidential security routine inspections

Core Product Advantages

Full-spectrum Junction Identification Capability

Unique detection algorithm enables recognition of two core target types:

All semiconductor junctions inside circuit boards, chips, micro-components and electronic gadgets

Rusted metal junctions that generate false harmonic signals, helping operators distinguish real electronic threats from metal interferences

Detection Valid for Powered & Powered-Off Electronic Devices

Unlike ordinary radio frequency detectors that only capture active transmitting signals, the VS-810 responds to the inherent semiconductor junction characteristics of electronic hardware. It successfully identifies surveillance devices even when the targets are fully shut down, dormant or with batteries removed, eliminating major blind spots in confidential anti-eavesdropping inspections.

Multi-Mode Alert Mechanism

Upon detecting semiconductor electronic equipment or rusted metal junctions, the detector activates three synchronized reminder modes to adapt to all inspection environments:

Visual alert: Real-time LCD display showing harmonic signal strength to judge target position and distance

Audio alert: Adjustable sound output via built-in speaker or dedicated monitoring headphones for discrete indoor confidential sweeps

Vibration alert: Silent vibration reminder for noise-restricted scenarios to avoid exposing inspection operations

Authoritative National Standard Certification

Passed full testing and certification by China’s official authoritative security testing institutions, fully compliant with GA 1236-2015 national industry standard for nonlinear junction detectors, rated Class C—the highest performance grade stipulated in the standard.

Ultra-High Detection Sensitivity

Equipped with a built-in high-gain directional antenna, the receiving sensitivity reaches as low as -140dBm. It can capture weak harmonic echoes from tiny micro-semiconductor components buried deep inside walls, furniture and multi-layer packaging materials.

Industry-Leading Penetration & Long-Range Detection

Penetration performance: Reliably detect targets through 370mm thick solid brick walls, meeting top Class C standard requirements

Maximum effective detection distance: ≥ 6 meters, supporting large-area rapid indoor sweeping with high efficiency

Long-Lasting Battery & Fast Charging

Adopts replaceable lithium battery packs. Under maximum pulse transmit mode, single-battery continuous working time exceeds 4 hours, enough to complete full single-site confidential inspection tasks. Each battery only takes 2.5 hours to reach full charge via fast charging design.

Independent R&D & Stable Supply

SZ Vodasafe holds complete independent intellectual property rights for hardware and software of the VS-810 series, with full in-house production and strict quality control. The product features stable consistent quality and short delivery cycles, supporting bulk orders for system integrators, government procurement and global security distributors.

Wide Environmental Adaptability

Works stably under complex indoor and outdoor conditions: operating temperature from -10℃ to +55℃, tolerable working humidity up to 93%RH at 40℃ (non-condensing), suitable for long-term indoor confidential anti-leakage screening work.

Lightweight Ergonomic Handheld Design

Compact overall dimensions of 760mm × 114mm × 96mm with a net weight of only 1.48kg ± 0.05kg, reducing operator fatigue during long-duration indoor full-space detection.

Working Principle

The VS-810 transmits fundamental radio waves at 2.4GHz–2.5GHz. When the radio frequency signal hits semiconductor junctions inside electronic devices or rusted metal junctions, second and third harmonic echo signals (4.8GHz~5.0GHz / 7.2GHz~7.5GHz) will be generated.

The built-in high-sensitivity receiver captures these harmonic signals, and self-developed precise phase filtering algorithms analyze the signal features to distinguish real hidden electronic equipment from ordinary metal interference. Once valid junctions are identified, the device automatically triggers visual, audio and vibration alarms to remind inspectors of hidden targets.
