 Alarm Rule: The alarm rule varies according to different types. The rule is to
compare the temperature information of two selected regions. For targets set
by frame, the rules include: Max. Temperature is Higher than, Max.
Temperature is Lower than, Min. Temperature is Higher than, Min.
Temperature is Lower than, Average Temperature is Higher than, Average
Temperature is Lower than, Temperature Difference is Higher than, and
Temperature Difference is Lower than. For targets set by line, the rules
include Max. Temperature, Min. Temperature, and Average Temperature. For
targets set by point, the rules are distinguished by Average Temperature.
 Pre-Alarm Temperature and Alarm Temperature: Set the pre-alarm
temperature and alarm temperature, the device sends pre-alarm when its
rule temperature exceeds pre-alarm temperature and sends alarm when its
rule temperature exceeds alarm temperature.
 Tolerance Temperature: Set the tolerance temperature and the device judges
whether the triggered alarm stops until the device temperature/temperature
difference is lower than rule temperature by tolerance temperature. For
example, set tolerance temperature as 3°C, set alarm temperature as 55°C,
