The Hikvision DS-2TD4136-25, and DS-2TD4136-50 Thermal & Optical Bi-spectrum Network Speed Dome use a vanadium oxide uncooled focal plane sensor to enhance thermal image quality.

The high sensitivity sensor has 384 x 288 resolution and features contrast adjustment for optimized images. AGC (Automatic Gain Control), 3D DNR (Dynamic Noise Reduction), and Dynamic Detail Enhancement further enhance image quality.

This series of cameras also features advanced fire detection and a wide range of Smart functions, including temperature exception, line crossing, intrusion, and region entrance and exit, benefitting users with great improvements in security efficiency and, more importantly, with key events and objects being recorded for further forensic needs.

The cameras can be outfitted with 25 mm or 50 mm lens to cover a variety of needs.
