This Hikvision bi-spectrum bullet combines a 384 × 288 vanadium oxide uncooled thermal sensor with 12 μm pixel pitch and NETD of 20 mK or less on a 35 mm F1.0 lens, alongside a 1/2.7-inch 4MP optical sensor on a 12.4 mm lens. Video content analysis 3.0 classifies humans and vehicles for line crossing, intrusion, region entrance and region exiting rules, with detection ranges of around 455 m for people and 1,050 m for vehicles. Temperature exception alarms cover -20 °C to 150 °C with ±8 °C accuracy, and dynamic fire detection can track up to 10 fire points, supported by a sun-reflection filter algorithm. Bi-spectrum image fusion overlays optical detail on the thermal image, and the optical channel has 120 dB WDR and IR illumination up to 100 m. The housing is rated IP67 and IK10 with NEMA 4X anti-corrosion protection and TVS 4000 V lightning protection, operating from -40 °C to 70 °C. A built-in TPM 2.0 encryption module protects the device, and power is via 12 VDC, 24 VAC or PoE (802.3af).
