The DS-2TD4167-25-W is a Thermal & Optical Bi-spectrum Network Speed Dome that offers advanced perimeter protection functions based on intelligent algorithms, including line crossing, intrusion, region entrance, and exit detection. It features a temperature exception alarm for fire prevention and a high-resolution thermal sensor (640 × 512) with a 17 μm VOx UFPA and NETD ≤ 40 mK (25 °C, F# = 1.1). The device incorporates sophisticated image processing technologies such as linear, histogram, and self-adaptive thermal AGC mode, DDE, and 3D DNR. With a high-quality detector guaranteed for 10 years, it supports smart tracking modes like panorama tracking, event tracking, and multi-scene patrol tracking. The thermal channel includes EIS, though it conflicts with intelligent functions, and it also features a fire and smoke detection algorithm.
