Camera requirements for the operation of the Smoke Detection are given in the table:
Camera
We recommend using color cameras. With black and white cameras, the detection quality can be noticeably worse
Resolution must be at least 640x360
FPS directly affects detection efficiency. In most cases, the default value (1 detection per 10 seconds) is sufficient to detect smoke that lasts more than one minute
Scene
The minimum smoke area in the frame depends on the neural network that you use. For a standard neural network (seeConfiguring Fire Detection), the smoke area must occupy at least 10% of the frame
In some cases, when smoke is clearly visible, the width/height of the smoke area can be sufficient at 1-3% of the frame width/height.
Smoke must be visually separated from the background
If you set a rectangular recognition area for the detection tool, the requirements apply to this area rather than to the entire frame.
