The requirements for cameras that will work with the the Fire detection module are follows: and Smoke detection modules are shown in the following table.

It's

Camera

  • Resolution is not less than 640x480.
  • FPS: any, 1 by default
    • It is recommended to use color cameras.
    Quality of recognition can be worse while using
    • With black and white cameras

    Object images

    • Fire area is not less than 10% from the frame area.
    Lightning
    • Any

    Hardware requirements are as follows:

    ...

    • , the recognition quality may be much worse
    • Resolution should be at least 640x360 pixels
    • Number of frames: the response rate of the detection module depends on the number of frames per second, by default, it is 1 per every 10 seconds (in most cases, it is enough to detect a fire/smoke that lasts more than 1 minute)
    Lighting
    • Fire/smoke should be visually separated from the background

    Object images

    • The minimum area of fire/smoke in the frame depends on the neural network used. For a standard neural network (see Configuring the Fire detection and Smoke detection modules), the area of fire/smoke should be at least 10% of the frame. In some cases, when the fire is well contained, it may be sufficient for a detection tool that the width/height of the fire zone is 1-3% of the width/height of the frame.


    Note
    titleAttention!

    If the area of interest is specified on the video image, then the above requirements are relevant for it, and not for the entire frame (see Configuring the Fire detection and Smoke detection modules)
