Set Line Crossing Detection
Detects objects crossing a pre-defined virtual line. If it occurs, the device can take linkage actions.
Steps
1. Go to Configuration → Event → Smart Event → Line Crossing Detection.
2. Check Enable.
3. Select one Line and set the size filter. For the size filter settings, refer to Set Size Filter.
4. Click Draw Area and a line with an arrow appears in the live video. Drag the line to the location on the
live video as desired.
5. Set rules.
• Direction: The direction from which an object goes across the line.
• A<->B: An object going across the line from both directions can be detected and alarms are
triggered.
• A->B: Only n object crossing the configured line from the A side to the B side will be detected.
• B->A: Only an object crossing the configured line from the B side to the A side will be detected.
• Sensitivity: Percentage of body part of an acceptable target that crosses the pre-defined line.
Sensitivity = 100 - S1/ST × 100. S1 is the target body part that crosses the pre-defined line. ST is the
complete target body. The higher the sensitivity value, the more easily the alarm is triggered.
• Object: Specify the object type to be detected and the device will detect only that object type.
