1. Use color cameras. With black and white cameras, the detection quality can be noticeably worse.
2. The video resolution must be at least 640x360.

3. FPS directly affects detection efficiency; in most cases, the default value (1 frame detection per 10 seconds) is sufficient to detect smoke or fire which develops in more than one minute.

4. The minimal recognized fire/smoke area depends on the particular neural network used. For a standard neural network (see Configuring Smoke and Fire Detection Tools), the fire/smoke area must occupy at least 10% of the frame.

   Info
   title 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.

   
   

5. Fire/smoke should be visually separated from the background.
