Please follow these recommendations for proper fire and smoke detection:
FPS directly affects detection efficiency: in most cases, the default value (1 detection per 10 seconds) is sufficient to detect smoke or fire which develops in more than one minute.
The minimal recognized fire/smoke area depends on the particular neural network used. For a standard neural network (see Configuring Fire and Smoke Detection Tools), the fire/smoke area must occupy at least 10% of the frame.
Note
In some cases, when fire is expected to be clearly visible, the fire area may be sufficient at 1-3% of the FoV width/height.
Attention!
If you set a rectangular recognition area for the detection tool, the limitations apply to this area rather than to the entire frame (see Configuring Fire and Smoke Detection Tools).
