The Hikvision HM-TD4137-25/50/WY is a professional bi-spectrum PTZ network speed dome that combines thermal imaging and optical video surveillance in a single intelligent platform. Designed for perimeter protection, critical infrastructure, industrial facilities, airports, ports, energy sites, and large-scale outdoor security projects, the camera delivers reliable detection and monitoring in complete darkness, fog, smoke, rain, and adverse weather conditions.

The thermal module utilizes a 384 × 288 VOx uncooled detector with NETD below 40 mK, enabling accurate thermal detection and early fire warning capabilities. The optical module features a 4MP camera with a powerful 40× optical zoom lens for detailed visual verification of detected targets. Advanced AI functions include line crossing detection, intrusion detection, region entrance/exit monitoring, fire detection, temperature anomaly alarms, and intelligent smart tracking.

Its rugged PTZ platform supports 360° continuous rotation, automatic target tracking, H.265+ compression, IP networking, local storage, and long-range IR illumination, making it ideal for professional security operations and critical asset protection.
