Issue with Bounding Box Sync in Milestone XProtect System during playback

We have recently added a camera to Milestone XProtect system as a ONVIF conformant device with Metadata enabled.

In the Milestone Smart Client, the bounding box appears to synchronize properly with the video during live view.

However, during playback, we have noticed that the bounding box is not aligned with the video—specifically, it plays ahead of the video footage.

Please find the attached video for your reference.

Note: Both the camera and the system are time-synced.

  • Windows OS version: Windows Server 2019
  • Milestone Version: XProtect Corporate 2025 R2
