AXIS Cross Line Detection
AXIS Cross Line Detection
AXIS Cross Line Detection is a trip-wire application installable on Axis network cameras and encoders. The application detects
moving objects that cross a virtual line making it possible to automatically trigger an event. AXIS Cross Line Detection will
increase system efficiency by reducing bandwidth and storage needs and facilitate search of recorded events.
The Cross Line Detection can be uploaded and used in Axis products that support AXIS Application Platform. The Applications
feature allows you to upload third party applications. For a complete list of products that support Axis Application Platform
got to www.axis.com
Recommendations and limitations
Cross Line Detection should not be used in critical scenarios that may have life or death situations, nor should it be used to
alert law enforcement. Cross Line Detection should not be used to monitor an entire restricted area, however it can be used to
monitor an entry to a restricted area.
Cross Line Detection should only be installed in cameras that are not subject to excessive vibrations. Some conditions might
affect the reliability of detection such as weather conditions (snow or rain), excessive lighting conditions and if object
movement is too slow or fast.
It is not recommended to run Cross Line Detection at the same time as the camera’s included application Motion Detection or
another Application Package installed in the camera.
