CSL 952 NLJD Wireless
Wireless Portable Non-Linear Junction Detector
The CSL 952 NLJD WIRELESS is a compact, portable non-linear junction detector designed for professional counter-surveillance and TSCM operations. It is capable of detecting concealed electronic devices hidden within walls, floors, ceilings, furniture, lighting, and containers, regardless of whether they are active, starting up, or dormant. Alerts are provided through display, vibration, and audio prompts, enabling operators to quickly locate and identify potential surveillance threats.
​
Using advanced AI-based harmonic analysis, the detector evaluates harmonic signals generated by electronic components and identifies suspicious devices or metal corrosion nodes in the detection area. This makes the CSL 952 NLJD WIRELESS an essential tool for protecting sensitive information and maintaining privacy in corporate, government, and personal environments.
Technology Principal:
The transmitting end of the CSL 952 NLJD WIRELESS emits an S-band fundamental wave toward the target area. The receiving end captures second and third harmonic signals generated by the target object. These signals are analysed using AI algorithms to detect and identify semiconductor-based devices and other suspicious anomalies in the search area.
Key Features:
-
Fully independent intellectual property (IPR) design, enabling customised feature updates
-
High accuracy with second and third harmonic detection
-
High sensitivity for locating semiconductors hidden in structures and furniture
-
Low false positive rate using a non-destructive detection algorithm
-
Safe for human use and compliant with radiation environmental guidelines
-
Simple, intuitive operation with minimal manual controls
-
Energy-saving automatic shutdown when idle
