Yes sir. Directly to the RS232 port. Hadn't considered the null modem cable as I've used a USB to RS232 cable before to access devices. Thanks for pointing out where I went wrong.

Null modem cable obtained. Pressing Ctrl+U does nothing inside of Putty. I assume because of the firmware was modified by Alibi from the stock firmware of Hikvision. Looking through the help segment I can see no mention of upgrade.

Are you seeing the bootup process now via the serial console?

Control-U needs to be pressed so it auto-repeats before the NVR is powered on.

I don't think that's likely, for the bootloader.
Also check out this tftp updater method of applying firmware without the need for authentication :

Yes, I can see the boot process. And perhaps that's where I'm going wrong, I was pessing Control+U after powering on the unit. I will give that a try tomorrow.
