how to downgrade the DS-2CD2T87G2H-LI firmware from version 5.7.13_230504 to 5.7.11_221009 (ONVIF not working on NVR devices using firmware 5.7.13_230504)
Have you tried just upgrading to this newer firmware version - V5.7.13-SP2_230706
It looks from the release note like it fixes several issues and might resolve the ONVIF issue you have been seeing.
What exactly is the ONVIF issue? Are you trying to connect the Hik camera to a 3rd-party ONVIF NVR? Does the Hikvision camera no longer have the option to enable ONVIF under the network settings when running the v5.7.13 firmware?
Hi @Dan
I already try to upgrade to newer firmware version - V5.7.13-SP2_230706
I try to connect the Hik camera to a 3rd-party ONVIF NVR ( Dahua NVR5232).
The NVR only support Onvif Digest Authentication to the firmware version 5.7.11_221009.
