Hi – as it says, I need to – apparently, – upgrade the Firmware to solve a camera problem where it is not recording audio.
How do I actually do this ? My NVR only has one USB port – where the mouse is plugged in........? if I plug in a USB stick with the .PAK file how am I meant to be able to control the UI to upgrade it?
It's Catch 22!
I feel I must be missing something but I have no idea what!
I just use a standard USB 2.0 splitter/hub so that I can have a mouse and thumb drive connected in parallel.
