Requirements for the operation of the Fire Detection detector 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 fires that last more than one minute
| Note |
|---|
| Correct operation of the detection tool detector isn't guaranteed if you use frames that were masked before they got into Axxon One by an IP camera or similar methods. |
|
| Scene and angle | - The minimum fire area in the frame depends on the neural network that you use. For a standard neural network (see Configuring the Fire Detectiondetector), the fire area must occupy at least 10% of the frame
| Info |
|---|
| In some cases, when fire is clearly visible, the width/height of the fire area can be sufficient at 1-3% of the frame width/height. |
- Fire must be visually separated from the background
|
| Note |

|
If you set a rectangular recognition area for the detection tooldetector, the requirements apply to this area rather than to the entire frame (see Configuring the Fire Detectiondetector). |
