Product Description

2.4GHz High Sensitivity Junction Detector For Government department Use




In 21th century, information leakage and eavesdropping cause lots of trouble and damage for government and company. In order to help special department protect secrets. Our company develops ZD-JD007  junction detector. With the high detection sensitivity less than -135dbm, it is able to detect any electronic device hidden in walls, floors, ceilings, lamps, furniture or containers. Where these electronic devices are transmitting singers or not, they are detected and alerted by display, vibration and sound prompts. Then detector can focus on hidden targets. 



Application scenes

1. Government Secrecy Department such as public security, justic, prisons, education, troops, and so on.

2. Security inspection of large scale activities

3. Confidentiality Inspection of Commerical Organizations

4. Cheating Prevention In Education Industry Examination


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.
  • Low false alarm rate: The built-in nondestructive detection algorithm greatly improves the detection ability, and the false alarm rate is very low.
  • Safety and reliability: The characteristics of equipment meet the requirements of electromagnetic radiation and are absolutely safe for human body. 
  • 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.
  • Flexible operation: The interface is simple and intuitive, with few buttons and easy manual operation.
