AXIS Perimeter Defender
Troubleshooting
Although the target is in the scene it’s
not matching a conditional scenario, for
example not moving from one zone to
another in the zone crossing scenario.
Make sure the scenario is correctly
specied, including conditions.
No alarms are triggered in the
AXIS Perimeter Defender setup on the
conguration computer even though the
analysis is running and the overlay is
visible.
Poor detection. Make sure the mounting requirements
are met. See Mount the camera on page
12. Also make sure that the calibration is
precise enough and that the sensitivity
is high enough.
Performance troubleshooting
Problem Possible reason
Solution
OSD and analysis keeps switching on and
off.
CPU charge on the camera is too high.
Possible solutions:
• Make sure the stream of the
camera is not visualized in
unnecessary places because
every visualization of the
camera stream increase CPU
load.
• If recording on in-built
motion detection is activated
try to decrease the quality of
the recording to free up CPU.
• Deactivate recording on
in-built motion detection and
make sure in-built motion
detection is deactivated.
A target enters the sterile zone and
causes multiple alerts to be raised.
The duration of the post-alarm time is
too short.
Adjust the post-alarm time. Go to
AXIS Perimeter Defender Setup >
Outputs.
Contrast of the object against the
background in the scene is too low.
Make sure the mounting requirements are
met. See Mount the camera on page 12.
There is inadequate lighting in the scene
or the low light performance of the
camera is insufcient.
Make sure the mounting requirements are
met. See Mount the camera on page 12.
AXIS Perimeter Defender has the
sensitivity set too low.
Increase the sensitivity in the global
scenario parameters.
Camera has moved rendering the
calibration incorrect.
Redo the calibration.
The calibration is not precise enough.
Verify the calibration of the camera. Go
to AXIS Perimeter Defender Setup.
A potential target enters the sterile zone
but does not raise an alert – missed
detection.
Although the target is in the scene it is
not matching a conditional scenario e.g.
not moving from one zone to another in
the zone crossing scenario.
Make sure the scenario is correctly
specied, including conditions.
