I was given an older Dahua DHI-NVR5416-16P box which has kicked off my IP camera deployment at home.
I'm struggling to Google much info about this box as the model number is so similar to later revisions, but this is just '16P' with nothing extra (not AI/ANZ, EI, 4KS2 etc). Could anyone please point me in the right direction for documentation? Apologies as I've already tried to search in various forums and locations but it's hard to find the right information given the model # similarities.
I'm specifically interested in whether I have the latest firmware for this box and whether it can/should be upgraded. I'm aware that it's far from ideal running something this old, but should I be concerned about anything in particular eg. network security, missing features etc? It's hard to beat free and I'll probably upgrade in the short to medium term, but I'll hold onto it for now (unless there are serious issues with using it?)
Thanks!
