Premium dual-spectrum thermal imaging for high-end perimeter and critical infrastructure security. The Hikvision DS-2TD4228-7/S2 is a high-performance PTZ camera that combines thermal and optical imaging with up to 800 m effective detection range, 30× optical zoom and advanced analytics. Built for demanding South African installations, it delivers reliable detection, tracking and monitoring even in total darkness or harsh environments.
Why this speed dome stands out
Security threats don’t wait for daylight. With the DS-2TD4228-7/S2, you get both thermal and visible-light imagery in a single housing—so you can detect heat signatures at long range and then zoom in with optical clarity for identification. This dual-spectrum design gives you both breadth and detail in one streamlined system.
