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
2. corresponding module.

In the Minimum alarm time, s
3. 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.
4. In the Alarm duration, sec field, enter the time period in seconds during which the repeated fire/smoke
alarms
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).

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

9. 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.

10. Set the Generate alarm on camera checkbox if
it is necessary
11. you want to initiate an alarm on the camera when
a detector is triggered

26. In the Frames processed per second [0.016, 100] field, set the number of frames per second that
will be processed by
27. 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
28. generating an alarm, if required.

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

30. to 20 for the detector to analyze before

triggering

31. generating 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.

Multiplication of Minimum alarm time, s and Number of frames for analysis and output [5, 20] values is the time period (in seconds) after which the alarm will trigger after the fire/smoke detection.

    Info
    title Note
    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.

38. 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:
 
39. The NVIDIA GPU gets the highest priority, followed by the Intel GPU, then the CPU.
    

    Note
    title Attention!
    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).
