CSL 953 NLJD Infra
Infrared Imaging Enabled Non-Linear Junction Detector
The CSL 953 NLJD INFRA is an advanced non-linear junction detector (NLJD) that integrates infrared thermal imaging with traditional NLJD detection. This innovative combination allows operators to locate concealed electronic devices, whether powered on or off, within walls, floors, ceilings, furniture, lighting, and containers.
​
Detection results are communicated through screen display, sound, and vibration, providing immediate feedback during inspections. The infrared imaging function enhances detection by visually highlighting the thermal outline of suspicious electronic devices, significantly improving efficiency and reducing false alarms during security sweeps.
Technology Principal:
The CSL 953 NLJD INFRA combines infrared imaging with non-linear junction detection. The transmitter emits an S-band fundamental wave, while the receiver captures second and third harmonic signals produced by electronic components. These harmonic signals are analysed using AI algorithms to identify suspicious electronic devices. Simultaneously, the infrared imaging module displays a real-time thermal outline of heated objects in the detection area, assisting operators in quickly identifying and verifying potential threats.
Key Features:
-
Infrared imaging function for real-time thermal visualisation
-
High accuracy using second and third harmonic detection
-
Low false alarm rate with non-destructive detection algorithm
-
Simple, intuitive operation with minimal controls
-
Cost-effective solution with strong performance
