@wittaj @watchful_ip I have similar issue.
I got a DS-2CD3145F-IS (dome) few years ago which has 5.4.52 firmware on it. I am pretty sure it is hacked Chinese as the sticker on camera shows 5.5.0_170728 firmware.
I do not have NVR and use NAS storage for recording (I have 4 other Hikvisions than can record to NAS)
everything is fine with camera except it can not record either on SD card or into NAS. because of this I just put it away and did not use it. (obviously if you can not record, camera is useless)
is there a way to fix this issue with current firmware? if not if I put the original Chinese firmware or the one
@tazman did (screenshot in few post ago) will this fix the NAS recording storage issue?
I don't mind the Chinese language as long as it can work. (better than camera collecting dust in my closet!!!!)
