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

  1. Go to
  2. the appropriate detector object's control panel
  3. the settings panel of the corresponding module.
    Image Modified
  4. In the Minimum alarm time, sec field (1)
  5. To receive events about the end of fire/smoke only after the time period from the Alarm duration, sec setting, set the Track alarm end checkbox. By default, the checkbox is cleared, which means that events about the end of fire/smoke are received immediately.
  6. In the Alarm duration, sec field, enter the time period in seconds during which the repeated
  7. recognitions of the ignition
  8. fire/smoke
  9. will be ignoredSet the Track alarm end checkbox (2) if it is necessary to generate an end-of-alarm event only after the expiration of the time, which is considered as: "time of the last received alarm" + "time specified in the Minimum alarm time, sec parameter"
  10. 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).
    Info
    titleNote
  11. For example, if 5 seconds is set for the Time in seconds between processed frames parameter, and there is a fire/smoke on the image during a longer period of time, then in order to avoid receiving messages of ignition/smoke from the detector every 5 seconds, set a higher value for the Minimum alarm time, sec parameter (for example, 10 seconds). In this case, only one message about the ignition/smoke will be displayed, and all the repeated recognitions will not be displayed in the Event viewer until the time interval between the recognitions of the ignition/smoke becomes longer than 10 seconds.

  12. If you set the Track alarm end checkbox, the events about the end of fire/smoke are received after the time specified in the Alarm duration, sec setting. If, until the end of this period, the current fire/smoke is completed and the new one is detected, the detector doesn't generate events about completing the current and starting the new alarm. The new fire/smoke event is received after the current alarm is completed.

  13. Set the Generate alarm on camera checkbox
  14. (3) if it is necessary
  15. if you want to initiate an alarm on the camera when
  16. a detection tool is triggered.

    If you use a custom neural network, click the Image Removed button (4), and in the standard Windows box that opens, select the neural network file with the fire/smoke detection model. It is not necessary to select standard neural networks in this field, the system will automatically select the required one. Standard neural networks for different processor types used are located in the C:\Program Files (x86)\Intellect\Modules64 directory:

  17. the detector generates an event.
  18. By default, the standard (default) neural network is initialized according to the device selected in step 10. You must not select the standard neural networks for the different processor types manually, since it is performed automatically. If there is a unique neural network for use, click the Image Added button to the right of the Tracking model field, and specify its file in the standard Windows Explorer window that opens.
  19. In the Detection sensitivity [0, 100] field, enter the detector sensitivity—an integer value in the range

  29. 100, the detector neural network must get 100% certainty for some period of time during the frame processing. The value of the Detection sensitivity field is determined experimentally.

  54. Set the Scanning mode checkbox to track small objects. If you enable this mode, the load on the system increases. That is why we recommend setting the small number of frames processed per second in step 7. By default, the checkbox is cleared. For more information on the scanning mode, see Configuring the Scanning mode.

    You cannot configure the scanning windows for the Fire detection and Smoke detection modules.
