Set Line Crossing Detection - HIKVISION DS-2XC6285G0-L User Manual

Threshold stands for the threshold for the time of the object loitering in the region. If the
time that one object stays exceeds the threshold, the alarm is triggered. The larger the value
of the threshold is, the longer the alarm triggering time is.
Sensitivity
Sensitivity stands for the percentage of the body part of an acceptable target that enters the
predefined region. Sensitivity = 100 - S1/ST × 100. S1 stands for the target body part that goes
across the predefined region. ST stands for the complete target body. The higher the value of
sensitivity is, the more easily the alarm can be triggered.
Target Validity
If you set a higher validity, the required target features should be more obvious, and the
alarm accuracy would be higher. The target with less obvious features would be missed.
5. Optional: You can set the parameters of multiple areas by repeating the above steps.
6. For the arming schedule settings, refer to Set Arming Schedule . For the linkage method settings,
