Hello user_D26_002,
hard to identify the root cause of the issue, without System Report / Camera Report and the Support Team from MOBOTIX.
I would check first two things:
- Is the camera time up to date?
- Is the POE Class and POE Switch correct?
this Community report highlight the details:
But the best case is to get back to the MOBOTIX Support and provide the Camera report as mention in the linked article.
