Tried upgrading DS-2CD2335FWD-I and 2385 today.
Cameras work fine locally after upgrade, but seems to be some compatibility issue with Qnap NVR software (same both models):-
1) V5.5.3- doesn't connect using Hikvision or Onvif, the black screen shows video format as MJPEG rather than H.264
2) V5.5.0 downgrade- works fine
3) V5.5.2- fails, same as 1)
4) V5.5.0 downgrade- again, works fine
I did try enabling Onvif/ cgi settings as suspected these may have been cause, no effect.
Will try...
G1 V5.5.x Firmware with Qnap NVR- black screen?
