Cross Line Detection - Interlogix TruVision 4 IP Series Configuration Manual

Cross line detection

This function can be used to detect people, vehicles and objects crossing a pre-defined
line or an area on-screen. The line crossing direction can be set as unidirectional or
bidirectional. Unidirectional is crossing the line from left to right or from right to left.
Bidirectional is crossing the line from both directions.
A series of linkage methods can be triggered if an object is detected crossing the line.
To define cross line detection:
1. From the menu toolbar, click
2. Check the Enable Cross Line Detection
3. Click Draw Area
4. Click the line and two red squares appear at each end. Drag one of the red squares
to define the arming area.
Select the direction as A<->B, A ->B, or B->A from the drop down menu (3):
A<->B: Only the arrow on the B side is displayed. When an object moves across the
plane in both directions, it is detected and alarms are triggered.
A->B: Only an object crossing the pre-defined line from the A to the B side can be
detected and trigger an alarm.
B->A: Only an object crossing the pre-defined line from the B to the A side can be
detected and trigger an alarm.
5. Set the sensitivity level (4) between 1 and 100.
6. If desired, select another line crossing area to configure from the dropdown menu.
Up to four line crossing areas can be configured.
7. Click Edit to set the arming schedule for the alarm input. See "Motion detection
alarms" on page 32 for more information.
