Video stream and scene requirements for the Fire Detectiondetector

Hardware requirements for neural analytics operation

Optimizing the operation of neural analytics on GPU in Windows OS

Optimizing the operation of neural analytics on GPU in Linux OS

To configure the Fire Detectiondetector, do the following:

  1. Go to the Detection Tools tab Detectors tab.
  2. Below the required camera, click Create… → Category: Production Safety → Fire Detection detector.

By default, the detection tool detector is enabled and set to detect fire.

If necessary, you can change the detection tool detector parameters. The list of parameters is given in the table:

Neural network file

Select a neural network file. The standard neural networks for different processor types are located in the C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK directory. You don't need to select the standard neural networks in this field, the system will automatically select the required one. If you use a custom neural network, enter a path to the file.

NoteFor the
Attention!
  • You cannot specify the network file in Windows OS. You must place the neural network file locally, that is, on the same server where you install Axxon One.
  • For correct neural network operation on Linux OS, place the corresponding file locally in the /opt/AxxonSoft/DetectorPack/NeuroSDK directory or in the network folder with the corresponding access rights.
  • If you use a standard neural network (training wasn't performed in operating conditions), we guarantee the overall accuracy of 80-95% and the percentage of false positives of 5-20% (see Data collection requirements for neural network training).
Ignore black and white imageYesThe parameter is disabled by default. If you don't want the
detection tool to trigger
detector to generate an event when the image is black and white, select the Yes value

Number of measurements in a row to trigger detection5

Specify the minimum number of frames

with fire for the detection tool to trigger

in which the detector must detect fire to generate an event. The value must be in the range [5

Scanning modeYesThe parameter is disabled by default. You can use the scanning
mode (see Configuring the Scanning
mode
)
to detect small objects
or
or objects in areas far away from the camera (see Configuring the scanning mode). For this, select the Yes value. This mode doesn’t provide absolute detection accuracy

Sensitivity 33

Specify the sensitivity of the

detection tool

detector empirically. The value must be in the range [1

;

, 99]. The default value is 33. The preview window displays the sensitivity scale of the

detection tool

detector that relates to the sensitivity parameter. If the scale is green, fire isn't detected. If the scale is yellow, fire is detected, but not enough to

trigger the tool

generate an event. If the scale is red, fire is detected, and the

detection tool will trigger, Example.

detector generates an event if the scale is red through the sampling period (50 seconds by default).

By default, the entire frame is the detection area. In the preview window, you can specify the detection areas using the anchor points (see Configuring a detection area):

  1. Right-click in the preview window.
  2. If you want to specify the detection area by one or more rectangles, select Detection area (rectangle). If you specify a rectangular area, the detection tool detector will analyze only this area. The rest of the frame will be is ignored.

  3. If you want to specify the detection area by one or more polygons, select Detection area (polygon). If you specify one or several polygonal areas, the detection tool detector will analyze the entire frame. The part of the frame not included in the specified polygons will be is blacked out.

    Note
    titleAttention!

    You can specify the detection areas similarly to the skip areas of the Scene analytics detection tools (see Configuring the Detection Zone). You must select the detection area (polygon or rectangle) experimentally. For some neural networks, the quality of detection will be better with a rectangle, for others—with a polygon.

  • For convenience of configuration, you can "freeze" the frame. Click the  button. To cancel the action, click this button again.
  • To hide the detection area, click the Image Modified button. To cancel the action, click this button again.
  • To delete the selected area, click the  button.

To save the parameters of the detection tooldetector, click the Apply  button. To cancel the changes, click the Cancel  button.
