DS-2TD4238-7/S2 - Thermal & Optical Bi-Spectrum PTZ Speed Dome Network Camera

The Hikvision DS-2TD4238-7/S2 is an advanced thermal and optical bi-spectrum network PTZ (Pan-Tilt-Zoom) speed dome camera equipped with a 7mm thermal lens and a 4.8-153mm 32x motorized optical zoom lens designed for intelligent perimeter protection and automated fire prevention. Backed by a high-quality detector with a 10-year guarantee, it utilizes a 384 × 288 resolution thermal sensor with an NETD of ≤ 35 mK to track heat signatures through total darkness, upscaling the output image to 1280 × 720 for enhanced operational clarity. The camera leverages its motorized pan-and-tilt capabilities to provide comprehensive Smart Tracking—including panorama, event, and multi-scene patrol options—seamlessly linking the thermal and optical channels to follow targets flagged by behavior analytics like line crossing, intrusion, and regional breaches. Additionally, it features high-precision smoke detection algorithms and temperature exception alarms ranging from -20°C to 150°C, making it an excellent dual-spectrum solution for manufacturing facilities, electrical substations, and hydropower infrastructure.
