Name: Thermal IP Hybrid Speed Dome Camera
Brand: Dahua
SKU: TPC-SD8641B

Covers long perimeter lines from one PTZ housing with a thermal and a visible camera.

The thermal detector maps heat at 640 × 512 resolution, while the 4 MP visible camera shows the same scene in color. AI rules recognize boats, engineering trucks and heat sources, and trigger email or external alarm linkage. The IP66 housing works outdoors from –40 °C to +70 °C.

Key features

45×

Optical zoom

The visible lens brings a distant target into close view at the tele end.

150m

Infrared illumination

The illuminator shows the scene up to 150 m in the dark.

300presets

Position memory

It stores frequently watched points; 8 tours step through 32 presets each.

18palettes

Thermal color palettes

It switches between palettes such as white hot, iron red and fusion.

512GB

Local recording

A micro SD card holds footage and fills the gap once the network returns.

7alarm inputs

External alarm wiring

Seven alarm inputs and two alarm outputs tie external sensors to the camera.

IN DAILY USE

Two images on one screenIt shows the thermal and visible streams side by side in a picture-in-picture layout.

Built for the weatherAn automatic rain sensor runs the wiper, which also extends wiper life.

Fast on targetThree-dimensional positioning turns the camera straight to the area the operator picks on screen.

Note

① Detection Distance: Detects objects, but cannot recognize their characteristics. Detected objects only cover a small amount of pixels (objects must cover more than 3.6 pixels of the image).
② Recognition Distance: Classifies objects into general categories, such as human, vehicle, and building (the object must cover more than 14 pixels of the image).
③ Identification Distance: Classifies objects into specific categories based on their characteristics, such as soldier, pickup truck, and gas station (the object must cover more than 28 pixels of the image).
