Name: Thermal Network Hybrid Speed Dome Camera
Brand: Dahua
SKU: TPC-SD8441B

Covers long-range surveillance with a thermal and a visible camera in a single housing.

The thermal detector picks up heat signatures in darkness and smoke, while the 4 MP visible camera delivers a color image of the same scene. AI rules tell boats, engineering trucks and heat sources apart and separate people from vehicles. The IP66 housing works outdoors from –40 °C to +70 °C.
