Hikvision DS-2TD2866-50 Thermal and Optical Bi-spectrum Network Bullet Camera

Protect critical assets with fast, reliable detection: the Hikvision DS-2TD2866-50 Thermal and Optical Bi-spectrum Network Bullet Camera is engineered for perimeter security, fire-prevention and continuous surveillance at airports, rail yards, power stations and other high-risk sites. Combining a high-sensitivity 640×512 thermal module (NETD < 40 mK) with a 2MP optical sensor, this bi-spectrum camera delivers fused thermal/visual imagery for rapid identification and verification — day or night.

Built-in temperature exception alarms and an advanced fire-detection algorithm give security teams early warning of hotspots and potential fires, while deep-learning behavior analysis (line crossing, intrusion, region entry/exit) reduces nuisance alerts. H.265/H.264 compression, wired network connectivity and remote management simplify integration into enterprise VMS/NVR systems and help lower storage and bandwidth costs. The IP66 weatherproof bullet housing and fixed 13mm lens provide dependable outdoor performance and easy wall-mount installation.

For facilities that require proactive monitoring and dependable event verification, the DS-2TD2866-50 is a scalable thermal imaging solution for perimeter security and continuous monitoring. Contact our sales team to request a quote or discuss system integration.
