A: NETD measures how small a temperature difference the camera detects. Less than 40mK means the camera identifies very small temperature variations. Higher sensitivity creates clearer thermal images with better detail. Q2: Can the camera detect people in complete darkness? A: Yes. The thermal sensor detects heat signatures without any light. People appear based on body heat against cooler backgrounds. Thermal imaging works regardless of lighting conditions. Q3: What triggers the white light and audio alarms? A: Alarms activate during detected security events like intrusion or tripwire breaches. AI analytics identify threats and trigger deterrence responses. Alarm settings configure through camera management software. Q4: What is the difference between 3.5mm, 7mm, and 10mm thermal lenses? A: Lens size affects field of view and detection distance. Smaller lenses (3.5mm) provide wider coverage but shorter detection range. Larger lenses (10mm) provide narrower coverage with longer detection distances. Q5: What does dual spectrum imaging mean? A: Dual spectrum combines thermal and visible imaging in one camera. Thermal captures heat signatures whilst visible captures standard video. Combined imaging provides comprehensive monitoring with both temperature and visual data.
