Question about a Error Log, we are not sure what this means for the Fusion

Dear Stereolabs Team we have some more questions about the fusion:

We have several PC reboot functions in place when the fusion is aborted or errors occur regarding sensor crqashes; however, there is one more occurrence we don’t know what it means regarding fused data:

  • A fused data is not sent indefinitly
  • B fused data gets sent, the warnign was only temporary? If after this last message nothging more appears
  • C we dont know whats happening at all

if A & C is correct we would program a restart there as well, can you give us some feedback on this?

This log show what we mean:
To be exact the last entry after sending fused data

[2026-02-20 08:55:58 UTC][ZED][WARNING] Timeout detected on camera [Fusion] . The camera will be removed from the synchronization until new data is available.

Hi @pachermann
What version of the ZED SDK are you using?
The latest v5.2 does not emit the warning reported in your log.

Are you using Fusion with data over a network? Is it a WiFi or cabled network?

We are using the USB and some older 4.x SDK.

And we cannot update, it will not work on never versions with fusion.
We are stuck on this older versions.

Normally, this is a simple warning emitted when the network has a communication problem, for example, caused by congestion.
When the information is received again, the processing restarts automatically without a notification.

Are you facing problems after this warning message?

Oh this is interesting.

We are not sure, we are trying to handle every possible problem scenario and figure out if it needs a reboot.

If i understand you correctly, we can’t know if it still broadcasts the fused data to unity on the IP on the machine when this error appears.

Is that correct?

Since we can’t attend the museum permanently, wea re not there to check if this Msg means the experience is broken.

You can check the status of the Fusion at any time by using the getProcessMetrics and the getSenderState API functions:
