5.4.2 Line Crossing
Line Crossing: Alarms will be triggered if the target crosses the pre-defined alarm lines.
Go to Config→Event→Line Crossing interface as shown below.
1. Enable line crossing detection and select the snapshot type and the detection target.
Save Original Picture to SD Card: If it is enabled, the detected pictures will be captured and
saved to the SD card when the targets cross the alarm line.
Save Target Picture to SD Card: If it is enabled, the detected target cutout pictures will be
captured and saved to the SD card when the targets cross the alarm line.
Note: To save snapshots to the local PC, please enable “Local Smart Snapshot Storage” in
the local config interface first. To save snapshots to the SD card, please install an SD card
first.
Detection Target:
Human: Select it and then alarms will be triggered if someone crosses the pre-defined alarm
lines.
Motor Vehicle: Select it and then alarms will be triggered if a vehicle with four or more wheels
(eg. a car, bus or truck) crosses the pre-defined alarm lines.
Non-motor Vehicle: Select it and then alarms will be triggered if a vehicle with two wheels
(eg. a motorcycle or bicycle) crosses the pre-defined alarm lines.
All of the three types of objects can be selected simultaneously. Please select the detection
objects as needed. If no object/target is selected, alarms will not be triggered even if line
crossing detection is enabled.
