Camera requirements for the Fire detection and Smoke detection modules |
The Fire detection and Smoke detection modules are configured similarly and as follows:
In the Minimum alarm time, sec field (1) enter the time period in seconds during which the repeated recognitions of the ignition/smoke will be ignored.
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. |
If you use a custom neural network, click the 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:
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 – integer value from 0 to 100. This parameter has an impact on sufficient probability of fire/smoke recognition for alarm.
For example, if sensitivity is 0, than frame on which fire/smoke is recognized with certainty more than 95% will be alarming. If sensitivity is 100, than frame with 50% certainty of fire/smoke recognition will be alarming. |
In the Number of frames for analysis and output field (7) enter minimum number of frames for detection analysis before alarm generating. The more the value, the more certain the result of detection operation. At the same time, if value is too large, the short-time fire/smoke can be missed.
Multiplication of Time in seconds between processed frames * Number of frames for analysis and output parameters characterizes time period (in seconds) at the end of which after fire/smoke alarm will be triggered. |
Configuring the Fire detection and Smoke detection modules is complete.
