DT-810 is a non-linear junction detector developed with modern advanced technology. It can detect any electronic equipment hidden in walls, floors, ceilings, lamps, furniture or containers. Whether these electronic devices are transmitting signals or not, they are alerted by display, vibration and sound prompts, so that the detectors can focus on hidden targets.

NLJD Detectors from iSecus-What can be detected

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.

Non-Linear Junction Detector Application Scenerios


  • High positioning accuracy: The product uses 2400MHz radio frequency detection technology with high precision positioning characteristics.

  • High semiconductor recognition ability: the product built-in spectrum analyzer supporting second and third harmonic detection can quickly and effectively identify devices containing semiconductors.

  • High Sensitivity: Especially for SIM card devices with high sensitivity, to ensure that secrets, mobile communications equipment can be quickly detected.

  • Low false alarm rate: built-in nondestructive detection algorithm greatly improves the detection capability, and the false alarm rate is very low.

  • High Safety and reliability: meets the requirements of electromagnetic radiation and absolute safety to human body.

  • Flexible operation: support automatic transmission power and manual mode selection, easy to operate manually

  • User-friendly interface: support OLED visual graphical interface, vivid display of power emission level and second and third harmonic graphics, easy to operate.

  • High performance/price rate: with the world most cost-effective, cost-saving and excellent performance.
