Oh, i've already this version from 2017 installed on it, Thanks anyway.
Thanks for your advice about the Swiss cheese, LOL. I will replace it as soon as I can find a newer one.
HI, I've also recently instaled an old DH-NVR7416-16p and would like to update it to a newest version. Do you still have the most recent firmware by any chance or do you know where I can get it ?
Thanks in advance for your help.
