Technical Principles:
The non-linear junction detector emits S-band fundamental wave to the target area or object, and the receiver captures the second and third harmonics generated by the target object. Artificial intelligence algorithm is used to analyze the harmonic law, so as to detect and identify the electronic equipment with non-linear junctions.
Application scenarios:
Nonlinear Junction Detector can be widely used in government, public security, prison, justice, army, education examination, business security and personal privacy protection, etc.
Business Safety: Detecting unauthorized electronic devices, such as eavesdroppers, mobile phones and devices with SIM cards, hidden in company board rooms or secret offices;
Public Safety: Detecting electronic devices hidden or prohibited from use in safe areas, such as detonating devices, remote controllers, etc.
Personal Privacy Protection: Cameras and surveillance devices like recording pens, cameras hidden in residential buildings and hotels.
