DS-2TD2637-35/QY(B) - Thermal & Optical Bi-spectrum Network Bullet Camera

The Hikvision DS-2TD2637-35/QY(B) is an industrial-grade, anti-corrosion bi-spectrum network bullet camera engineered for long-range perimeter security and proactive fire prevention in highly destructive, corrosive environments like ports, chemical plants, and critical infrastructure. Featuring a 384 × 288 thermal sensor backed by a 10-year detector guarantee alongside a high-definition 4MP optical module, it pairs a long-range 35 mm thermal lens with a highly magnifying 12 mm optical lens and an ultra-sensitive NETD ≤ 35 mK rating to deliver sharp, perfectly matched, fused dual-spectrum imagery through severe maritime fog, smoke, or total darkness. Driven by advanced deep-learning algorithms, the camera maximizes security efficiency with specialized human and vehicle target classification to filter out environmental false alarms during line crossing and intrusion detection, while its integrated fire detection and sun-reflection filter algorithms work alongside a -20°C to 150°C temperature exception alarm to instantly isolate actual thermal threats without triggering on false lens glares.
