Non-Linear Junction Detector (NLJD) with Infrared Imaging
The Non-Linear Junction Detector (NLJD) with Infrared Imaging transmits frequency spanning 2.4GHz to 2.5GHz with 0–4W EIRP maximum pulse output. The device receives second and third harmonics at 4.8GHz–5.0GHz and 7.2GHz–7.5GHz respectively. Receiver sensitivity reaches ≤-140dBm for detecting weak harmonic signals from semiconductor junctions. The unit measures 750mm × 114mm × 108mm and weighs 1.55kg. Detection range exceeds 6 meters and penetrates 370mm-thick brick walls, meeting GA1236-2015 C-level certification.
The infrared imaging system features a 160×120 pixel matrix with continuous thermal scanning. Thermal sensitivity measures less than 50mK (0.050°C), detecting minute temperature variations from active electronics. The 12µm pixel size, F/1.1 lens, and 57-degree field-of-view enable precise thermal identification. A replaceable lithium battery provides 7 hours standby time. The LCD display presents harmonic signal strength and infrared imagery simultaneously. Audio alerts transmit through headphones or external speakers. Vibration alerts function silently. Operating temperature ranges from -30°C to +55°C with humidity tolerance to 93%RH.
Security teams deploy the Non-Linear Junction Detector (NLJD) with Infrared Imaging during facility sweeps to locate concealed electronics. Operators combine harmonic detection with thermal imaging to confirm active devices versus dormant components. The cross-verification method identifies hidden cameras, listening devices, and transmitters regardless of power status. Law enforcement units scan correctional facilities for prohibited electronics. Military personnel conduct counter-surveillance and explosive detection. Corporate security teams inspect sensitive areas. The non-destructive detection algorithm minimizes false alarms from metallic corrosion.
Tactical Supply Pakistan delivers this integrated detector combining harmonic technology with thermal confirmation for professional security operations. The dual-detection approach significantly reduces false alarm rates while improving target accuracy across varied environments.
How does simultaneous NLJD and thermal imaging reduce false detections compared to traditional NLJD-only sweeps?
Thermal imaging confirms active electronic devices by detecting heat signatures from powered components or recent battery use. When both systems align—NLJD detecting harmonics and thermal showing heat—target identification confidence increases substantially, eliminating metallic debris and passive corrosion responses.
