Hikvision Heatpro Ds-2td2628-3/qa Replaced By Hm-td2628-3/g1/t3a Bi‑spectrum Thermal & Optical Bullet Camera – 256×192 Vox, Smart Vca, Fire & Smoking Alarm

The Hikvision Heatpro DS-2TD2628-3/QA, now replaced by the HM-TD2628-3/G1/T3A, is a bi-spectrum thermal and optical bullet camera engineered for simultaneous perimeter security and early fire detection. This rugged outdoor unit combines a high-sensitivity 256×192 VOx thermal sensor with a 4MP optical sensor to provide reliable scene assessment in darkness, fog, and smoke conditions.

Key Features

• 256×192 VOx uncooled focal plane array with 12 µm pixel pitch and NETD below 40 mK for high-sensitivity thermal imaging.
• 4MP optical sensor featuring 120 dB WDR and near-zero-lux performance for detailed visual context.
• Deep-learning VCA for accurate vehicle and human classification, reducing nuisance alerts from animals or environmental movement.
• Temperature exception alarms monitoring point, area, and line rules across a -20°C to 150°C range with ±8°C accuracy.
• Active smoke detection with sun-reflection filtering to distinguish genuine fire hazards from false positives.
• Support for up to 8 VCA rules to accommodate multi-zone perimeter layouts in industrial and commercial environments.
• Alert triggering via relay output, FTP, or email for immediate response to security or fire events.
