1. Go to the Fire detection object's control panel.
   

2. In the Skip repeated recognitions, sec field (1) enter the time period in seconds during which the repeated recognitions of the ignition will be ignored.

   Info
   title Note
   For example, if 5 seconds is set for the Time in seconds between processed frames parameter, and there is a fire on the image during a longer period of time, then in order to avoid receiving messages of ignition from the detector every 5 seconds, set a higher value for the Skip repeated recognitions, sec parameter (for example, 10 seconds). In this case, only one message about the ignition 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 becomes longer than 10 seconds.

   
   

3. In the Detection sensitivity: 0..100 field (2) enter the sensitivity of detection – integer value from 0 to 100. This parameter has an impact on sufficient probability of fire recognition for alarm.

   Info
   title Note
   For example, if sensitivity is 0, than frame on which fire is recognized with certainty more than 95% will be alarming. If sensitivity is 100, than frame with 50% certainty of fire recognition will be alarming.

   
   

4. In the Time in seconds between processed frames field (3) enter the time period in seconds separating frames used by algorithm for fire analysis. This parameter has an impact on processor capacity: the less the parameter, the more capacity. Also it has an impact on operation speed of algorithm: the less distance between frames. the faster required number of frames will be collected for decision and alarm, if it's required.

5. In the Number of frames for analysis and output field (4) 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 can be missed.

   Info
   title Note.
   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 alarm will be triggered.

   
   

6. In the Device drop-down list (5), select the device on which the fire detection will operate:
   1. Auto - automatic device selection.
   2. CPU - Central Processing Unit from Intel (not recommended).
   3. Nvidia NVIDIA GPU (depends on the number of Nvidia of NVIDIA  graphics cards installed).
7. Specify the detection surveillance area on the video image:
   1. Click the Setup button (6). The Detection settings window will open.
      
   2. Click the Stop video button to capture the video image (1).
   3. Click the Area of interest button (2).
   4. Specify area on which smoke recognition will be detected (3).
   5. Click the OK button (4).
8. Click the Apply button (7).
