Description:
DT-820 is a miniaturized non-linear junction detector as a professional tscm equipment. It can detect electronic devices hidden in walls, floors, ceilings, lamps, furniture or containers, whether they are transmitting signals or switching on or off, and alarm them by display, sound and vibration. This nljd detector can find the target equipment for protecting organizations and individuals Private information.
Technical Principles:
Nonlinear 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:
It 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: Hidden cameras and surveillance devices such as recording pens, cameras, etc. in residential buildings and hotels.
Features:
-
High positioning accuracy: The product uses 2400MHz radio frequency detection technology with high precision positioning characteristics.
