[KBA-78744] Legacy motion detection might stop working for Axis cameras after upgrading to Security Center 5.6
This article explains why, after upgrading to Security Center 5.6, recording might stop working for Axis cameras that are using legacy motion detection.
Legacy motion detection on video units stops working for Axis cameras that were enrolled in Security Center 5.5 and earlier, and then upgraded to Security Center 5.6 GA -5.6 SR4 CU5 (inclusive).
The affected cameras stop recording video triggered by motion detection events and a black timeline is displayed in the monitoring tile. This issue occurs even if sufficient motion is being detected by the camera.
A coding defect.
In Config Tool, reconnect the affected cameras.
IMPORTANT: After an Archiver restart, this problem might reoccur.
