alarm type, and then trigger the corresponding alarm actions.
The system supports heat alarm, temperature (temperature difference) and cold/hot alarm.

Heat alarm: The system generates an alarm once it detects there is a fire.
●
Temperature (temperature difference): The system triggers an alarm once the temperature
difference between two positions is higher or below the specified threshold.
●
Cold/hot alarm: The system triggers an alarm once the detected position temperature is higher
or below the specified threshold.
●
Make sure that the connected camera supports temperature monitoring function.
