Product Description

2400MHz Junction Detector With 120-200mm detection distance and light weight




ZD-JD007 is the advanced junction detector of our company to help government department, military camp and large company to protect secrets from eavesdropping and monitoring. People use it to detect any electronic device hidden in walls, floors, ceilings, lamps, furniture or containers. It has 120-200mm detection distance to detect electronic device hide deeply. Also, it is also designed with light weight of 1.5Kg and convenient to be taken by user. where these electronic devices are transmitting singers or not, they are detected and alerted by display, vibration and sound prompts. Then detector can sink the hidden targets. The long work time of 4 hours can make detector keep working during entire detection mission.



Application scenes


It can be widely used in government, public security, prison, justice, military, education examination, business security and personal privacy protection, etc.

Personal privacy protection: hidden camera and recording devices such as voice recorders, cameras, etc. in residences and hotels Wait.
Commercial security: detect unauthorized electronic devices hidden in company board meeting rooms or secret offices, such as bugs, mobile phones and public security such as devices containing SIM cards : detecting hidden and prohibited electronic devices in safe areas, such as detonating devices, remote controls, etc.;



Product Characteristics

  • Strong semiconductor detect ability: With the 2nd and 3rd harmonic signal strength detection technology, it can quickly and effectively identify device and semiconductor materials inside it.
  • High sensitivity: The junction detector is equipped with built-in high gain antenna. It has long detection distance especially for SIM card devices. To ensure secret, mobile communication equipment will be detected quickly.
  • Light weight: It has light weight of 1.5kg. People can carry it for long moment.
  • Friendly interaction interface: Support visual graphical interface, bright display of power emission level, 2nd and 3rd harmonic graphics, easy to operate.
  • High cost performance: The most cost-effective, cost saving and excellent performance in the world.
