HIKVISION DS-2TD2667-35/PY User Manual

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.
Reective Temperature
If there is any object with high emissivity in the scene, check and set the reective
temperature to correct the temperature. The reective temperature should be set the
same as the temperature of the high emissivity object.

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.
Tolerance Temperature
Set the tolerance temperature to prevent the constant temperature change to affect
the alarm. E.g., set tolerance temperature as 3 °C, set alarm temperature as 55 °C, and
set pre-alarm temperature as 50 °C. The device sends pre-alarm when its temperature
reaches 50 °C and it alarms when its temperature reaches 55 °C and only when the
device temperature is lower than 52 °C will the alarm be cancelled.
Pre-Alarm Output and Alarm Output
When the temperature of target exceeds the pre-alarm or alarm threshold, it triggers
the pre-alarm or alarm output of the connected device.
Area's Temperature Comparison
Select two areas and set the comparison rule, and set the temperature difference
threshold. The device alarms when the temperature difference meets the setting
value.
5.
Optional: Check Enable
Reect Light Filter and Enable Forklift Filter.
6.
Refer to Set Arming Schedule for setting scheduled time. Refer to Linkage Method
Settings for setting linkage method.
7.
Optional: Shield certain area from being detected. Refer to Set Temperature
Measurement Shield Region for detailed settings.
8.
Optional: Set the offsite pre-alarm/alarm specially during off-hours when there are less
causes of false alarms. You can set the lower alarm temperature to improve the
efciency of quick alarm.
