In the Minimum alarm time, secs field (1), enter the time period in seconds during which the repeated recognitions of the ignitionfire/smoke alarms will be ignored.

For example, if 5 seconds is set for the Time in seconds between processed frames parameterin the Minimum alarm time, sfield, and there is a fire/smoke on the image during a longer period of time, then in order to avoid receiving messages of ignitionabout the fire/smoke from the detector detection tool every 5 seconds, set a set a higher value for the the Minimum alarm time, sec parameter s parameter (for example, 10 seconds). In this case, only one message about the ignitionfire/smoke will be displayed, and all the repeated recognitions all the following alarms will not be displayed in the Event viewer until until the time interval between the recognitions the recognitions of the ignitionfire/smoke becomes longer than 10 seconds. |
If you use a custom unique neural network is prepared for use, in the Tracking model field, click the the button (4), and select the file and in the standard Windows box Explorer window 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 . If the field is left blank, the default neural networks will be used for detection (see the table below). They are selected automatically depending on the CPU and are located in the C:\Program Files (x86)\Axxon PSIM\Modules64 directory:
| Neural network name | Detection/CPU |
|---|---|
| smoke_openvino.ann | Smoke detection/CPU |
| smoke_original.ann | Smoke detection/GPU |
| fire_openvino.ann | Fire detection/CPU |
| fire_original.ann | Fire detection/GPU |
In the Detection sensitivity : [0..100] field (5), enter the sensitivity of detection – the detection tool — integer value in the range from 0 to 100. This parameter has an impact on sufficient probability determines at what certainty of fire/smoke recognition for alarmdetection the detection tool will trigger.

For example, if the sensitivity is 0, than then the frame on which fire/smoke is recognized with certainty detected with the certainty of more than 95% will be alarmingconsidered alarmed. If the sensitivity is 100, than then the frame with 50% certainty 50% certainty of fire/smoke recognition detection will be alarmingalarmed. |
In the Number of frames for analysis and output field (7), enter the minimum number of frames for the detection analysis before alarm generatingtool to analyze before triggering. The more higher the value, the more certain reliable the result of the detection tool operation. At the same time, if the value is too largehigh, the short-time fire/smoke can be missed.

Multiplication of Time in seconds between processed frames * of Minimum alarm time, s and Number of frames for analysis and output parameter values characterizes is the time period (in seconds) at the end of which after after which the alarm will trigger after the fire/smoke alarm will be triggereddetection. |
On the captured video image (3) sequentially specify nodal , set the anchor points of the area to be analyzed by , the situation in which you want to analyze, by sequentially clicking the left mouse button. It is possible to add only Only one area . While attempting can be added. If you try to add the a second area, the first one area will be deleted. After adding an area specifying , the remaining part rest of the video image will be darkened.
Click the OK button (2).
