Camera requirements for the Fire detection and Smoke detection modules

  • You can configure the Fire detection module on the settings panel of
  • the 
  • the Fire detection object created on the basis of the Camera object on the Hardware tab of the System settings window.
  • You can configure the Smoke detection module on the settings panel of the Smoke detection object created on the basis of the Camera object on the Hardware tab of the System settings window.

The To configure the Fire detection and Smoke detection modules are configured similarly and as follows modules, do the following:

  1. Go to the settings panel of the

  8. setting, set the Track alarm end checkbox. By default, the checkbox is
  9. clear
  10. cleared, which means that events about the end of fire/smoke are received immediately.
  11. In the Alarm duration, sec field, enter the time period in seconds during which the repeated fire/smoke alarm events are ignored. By default, the setting isn't available for editing. To enable it, you must set the Track alarm end checkbox (see the previous step).

  51. In the Frames processed per second [0.016, 100] field, set the number of frames per second that
  52. will be processed by
  53. the neural network processes. This value affects the processor load: the higher the value, the greater the load. It also affects the operation speed of the algorithm: the higher the frame rate, the faster the required number of frames are collected for making a decision and

  56. In the Number of frames for analysis and output [5, 20] field, enter the minimum number of frames in the range from 5

    Info
    titleNote

    You cannot configure the scanning windows for the Fire detection and Smoke detection modules. The default parameters are used.

    When you use the scanning mode, we recommend using a full frame without specifying the area of interest in step 11.

  76. From the Device drop-down list, select the device on which the neural network will operate: the CPU, one of the NVIDIA GPUs, or one of the Intel GPUs. Auto (default value)—the device is selected automatically:
  77.  
  78. The NVIDIA GPU gets the highest priority, followed by the Intel GPU, then the CPU.
    Note
    titleAttention!

    We recommend using the GPU.

    It can take several minutes to launch the algorithm on the NVIDIA GPU after you apply the settings. You can use caching to speed up future launches (see Optimizing the operation of neural analytics on GPU).

  79. Specify the area of interest on the video image:
    1. Click the Stop video button to capture the frame of the video image.

    2. Click the Area of interest button.
    3. On the captured video
