Hello. If anyone could help it would be greatly appreciated. I have a Hik vision system and I am looking to upgrade the firmware to the last released version. As my system is a few years old, I would imagine Hik Vision stopped supporting the NVR I have but I would not mind having the latest or last firmware update they released. I have looked around on the internet but to be honest I am confusing myself with the amount of info that's available. If anyone could point me in the right direction I would be most grateful. I have added a screen shot of my firmware which I hope will assist someone better qualified than me. Many thanks in advance.
