Câmara bi-spectrum térmica Hikvision HM-TD1228-7/G1/T3A 256x192

The Hikvision HM-TD1228-7/G1/T3A is a high-performance thermal bi-spectrum camera designed for critical security and fire detection applications. Combining a 256×192 thermal sensor with a 4 MP optical sensor, it delivers reliable 24/7 surveillance in challenging environments. With advanced analytics including fire detection, line crossing, and intrusion detection, this camera is ideal for perimeter protection, industrial monitoring, and early warning systems.

Advantages

Dual-spectrum imaging provides both thermal and visible light views, ensuring detection even in total darkness or through smoke. The 7 mm thermal lens offers a 24.9° × 18.7° field of view, while the 8 mm optical lens covers 39.42° × 22.14°. Built-in IR illumination extends night vision up to 30 m. The camera supports H.265+ compression for efficient bandwidth and storage, and features a microSD slot for up to 256 GB local storage. With IP66 rating, it withstands harsh weather conditions from -40 °C to 65 °C.
