Hi there, I'm new to this and Hikvision equipment. My NVR is a DS-7608NI-K2 / 8P and if I'm reading it right, the firmware on it is V3.4.107 build 190927.
Attached to this are 8 x Hilook poe ip cameras, IPC-T250H 2.8mm, 5mp. I'm not sure what firmware they're on or how to update it either. Sorry...
