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.
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)
