To configure smoke (fire) detection tool:

1. Set the

   minimum number of frames with smoke (fire) for triggering the tool (1). The value should be in the [5;20] range.

   Set the interval between the processes frames in seconds (21). The value should be in the [1;30] range.

   Info
   title Note
   The default values (5 frames and 10 seconds) indicate that the tool will analyze one frame every 10 seconds.  When smoke (fire) is detected in 5 frames, the tool will trigger.

2. Select the processor for the neural network — CPU, one of GPUs or a IntelNCS (2). 

3. Select a neural network file (3).  The following standard neural networks for different processor types are located in C:\Program Files\Common Files\AxxonSoft\DetectorPack\NeuroSDK :

   smoke_movidius.ann	Smoke detector / IntelNCS
   smoke_openvino.ann	Smoke detector / CPU
   smoke_original.ann	Smoke detector / GPU
   fire_movidius.ann	Fire detector / IntelNCS
   fire_openvino.ann	Fire detector / CPU
   fire_original.ann	Fire detector / GPU

   
   

4. Set the minimum number of frames with smoke (fire) for triggering the tool (4). The value should be in the [5;20] rangeSelect detection tool operation mode (3):
5. CPU - detection will be processed by means of CP.

Auto - the Server automatically determines how detection will be processed, either by means of CP or GP.

Note

title	Attention!

For stable operation of the detection tool, the next generation video card is required:

- at least 2 GB of memory,

- CUDA 5.0 support (minimum).
6. You can experiment with the sensitivity of the tool ( 4 ).  The value must be in the range [1; 99]. The preview window displays the sensitivity scale of the detection tool. It is color-coded as follows:

   1. Green - smoke (fire) not detected.  

   2. Yellow - smoke (fire) detected, but not enough to trigger the tool.

   3. Red - smoke (fire) detected.

      If you increase the sensitivity value, you have more alerts (red scale).
      

7. In the preview window, you can set the detection zones with the help of anchor points much like privacy masks in Scene Analytics (see Setting general zones for scene analytics). By default, the entire FoV is a detection zone.
