Camera requirements for the Fire detection and Smoke detection modules

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 appropriate modulecorresponding module.

  2. 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.
  3. In the Alarm duration, sec field, enter the time period in seconds during which the repeated fire/smoke

  5. 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).

  12. time, sfield, and there is a fire/smoke on the image during a longer period of time, then in order to avoid receiving messages about the fire/smoke from the detector every 5 seconds, set a higher value for the Minimum alarm time, s parameter (for example, 10 seconds). In this case, only one message about the fire/smoke is displayed, and all the following alarms aren't displayed in the Event viewer until the time interval between the recognitions of the fire/smoke becomes longer than 10 seconds.Set the Track alarm end checkbox if it is necessary to generate an end-of-alarm event only after the expiration of the time, which is counted as the time of the last received alarm + time specified in the Minimum alarm time, s parameter
  13. 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.

  14. Set the Generate alarm on camera checkbox if it is necessary you want to initiate an alarm on the camera when a detector is triggeredthe detector generates an event.
  15. By default, the standard (default) neural network is initialized according to the device selected in the Device drop-down list. The step 10. You must not select the standard neural networks for the different types of processors are selected processor types manually, since it is performed automatically. If there is a custom unique neural network is prepared for use, in theclick the Image Added button to the right of the Tracking model field, click the Image Removed button, and select the specify its file in the standard Windows Explorer window that opens.
  16. In the Detection sensitivity [0, 100] field, enter the detector sensitivity of the detector—an integer value in the range from 0 to 100. This parameter determines at what certainty of fire/smoke detection the detector will triggergenerates an alarm: the higher the sensitivity, the higher the recognition threshold. For example, at sensitivity 100, the detector neural network must get 100% certainty for some period of time when during the frame processing the frames. The value of the Detection sensitivity field is determined experimentally.

  17. In the Frames processed per second [0.016, 100] field, set the number of frames per second that will be processed by 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 triggering generating an alarm, if required.
  18. In the Number of frames for analysis and output [5, 20] field, enter the minimum number of frames in the range from 5 20to 20 for the detector to analyze before triggeringgenerating an alarm. The higher the value, the more reliable the result of the detector operation. At the same time, if the value is too high, the short-time fire/smoke can be missed. If you enter a value less than the minimum, the value is set to 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.

  30. 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:  The NVIDIA GPU gets the highest priority, followed by the Intel GPU, then the CPU.
    Note
    titleAttention!
    1. We recommend using the GPU.
    2. 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

    2. In the Detector Pack subsystem of version 2.0, the support of Intel HDDL is removed, therefore, when you update from version 1.0, the Not supported option is selected automatically instead of this device variant, and detectors don't operate. To resume the detector operation, select the required device from the list.

  31. 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 imageframe, sequentially set the anchor points of the area using the left mouse button, the situation in of which you want to analyze, by sequentially clicking the left mouse button. After you add an the area, the rest remaining part of the video image is darkened. If you don't specify the area of interest, the entire frame is analyzed.

    4. Click the OK button.
