I'm looking to update this old recorder see picture it's not been updated in about 10 years the firmware is 2015 on it, if somebody could point me in the right direction to update it.
Thanks.
I have a dahua nvr see pic, which I bought from AliExpress a while ago, it works well but it's on v3 firmware I would like to put it on version 4 on but every time I try and update it gets to about 50 to 60% then fails..
