4. To specify the forbidden crossing direction, click Select origin and then click one of the zones.
5. Under Detect, select what type of objects to detect.
6. Under Duration parameters, if you don’t want a zone to be activated as soon as an object enters, set the Min presence
in for one or both zones.
7. If the zone is narrow and can be crossed in 1–2 seconds, and you still want alarms to trigger, select Narrow zone. This
setting can’t be combined with Min presence in zone. For more information, see Duration parameters on page 26.

Set up the conditional scenario
The conditional scenario is designed to trigger an alarm when an object enters a certain zone without rst passing through others.
Under Duration parameters, you can dene a minimum presence time for each of the zones in the scenario. If T
A
is the minimum
time in the authorized zone and T
B
in the intrusion zone, an alarm only triggers if the object:
• stays longer than T
B
in the intrusion zone without having entered the authorized zone rst.
• stays shorter than T
A
in the authorized zone, then enters and stays longer than T
B
in the intrusion zone.
No alarm triggers if the object:
• doesn’t enter or stays shorter than T
B
in the intrusion zone.
• stays longer than T
A
in the authorized zone, then enters the intrusion zone (regardless of how long the object stays).

Pair the cameras - PTZ Autotracking
In the setup for AXIS Perimeter Defender PTZ Autotracking, you must pair the xed camera and the PTZ camera with each other to
make sure a moving object is tracked in an efcient way by the PTZ camera.
If you performed an automatic calibration, you can Perform an automatic pairing on page 28 of the two cameras. Otherwise you
need to Perform a manual pairing on page 28.
