How to get a stable UUID for an OnVif camera ?

[jfsmig]

Hi, everyone!

I am currently tinkering with an OnVif conformant cam (Reo6Link RLC-520) and I struggle to find a unique UUID for that device. I need something unique that would survive multiple DHCP leases.

No OnVif call seems to return the required information. The only potential UUID comes from the WS-discovery ProbeMatch reply.

1/ Is it that UUID the one I am expecting?
2/ What if I don't need the discovery, e.g.because I know the address and the netwrk doesn't support multicast for the discovery?

Thanks in advance!
Best regards

Hi, yes that UUID would survive multiple DHCP leases, but it will be regenerated if the device is factory defaulted. I don't know any way of getting this UUID without using WS-Discovery. Another ID (although not a UUID) that could be used is the serial number or hardware address that is returned by GetDeviceInfomation, see https://www.onvif.org/ver10/device/wsdl/devicemgmt.wsdl.

Thanks a lot, it confirms what I thought. The serial number I observe on my device is suspicious. I only have one camera to experiment with, so I cannot compare it. The L2 address could work, yes.
