III. Set Expert Mode
Select the temperature measurement rules from Point, Line, or Area and configure parameters, the device alarms if the alarm rules
are met.
Steps
1. Go to Configuration → Temperature Measurement → Basic Settings, check Enable Temperature Measurement.
2. Refer to Set Thermography Parameters to set the parameters.
3. Go to Configuration → Temperature Measurement → Advanced Settings, select Expert.
4. Select and enable the temperature measurement rules. Please refer to Set Thermography Rule for setting the rule.
5. Optional: Click Area's Temperature Comparison to set the alarm rules and the temperature.
6. Refer to Set Arming Schedule for setting scheduled time. Refer to Linkage Method Settings for setting linkage method.
7. Click Save.
The maximum temperature and thermography rules will be displayed on the liveview.
Note
Go to Image → VCA Rules Display to adjust the fonts size and the temperature colour of normal, alarm and pre-alarm.
IV. Set Thermography Rule
Steps
1. Customize the rule name.
2. Select the rule type to Point, Line, or Area. Then draw a point, line, or area on the interface where the position to be measured.
Point
Please refer to Point Thermographyfor detailed configuration.
Line
Please refer to Line Thermographyfor detailed configuration.
Area
Please refer to Area Thermographyfor detailed configuration.
3. Configure the temperature measurement parameters.
Emissivity
Set the emissivity of the target. The emissivity of the surface of a material is its effectiveness in emitting energy as thermal
radiation. Different objects have different emissivity. Refer to Common Material Emissivity Reference to search for the target
emissivity..
Distance
The distance between the target and the device.
Reflective Temperature
If there is any object with high emissivity in the scene, check and set the reflective temperature to correct the temperature.
The reflective temperature should be set the same as the temperature of the high emissivity object.
4. Click and set the Alarm Rule.
Alarm Temperature and Pre-Alarm Temperature
Set the alarm temperature and pre-alarm temperature. E.g., select Alarm Rule as Above (Average Temperature), set the Pre-
Alarm Temperature to 50 °C, and set the Alarm Temperature to 55 °C. The device pre-alarms when its average temperature is
higher than 50 °C and alarms when its average temperature is higher than 55 °C.
Filtering Time
It refers to the duration time after the target temperature reaches or exceeds the pre-alarm temperature/alarm temperature.
