CCRR can still be a China region device. My 7816 NVRs are China region and have RR in the serial number.
It can be quite hard to tell for sure what the hardware signature block holds.
One of the best indications is the '-NI' suffix in your model number. That suggests 'International'.
*edit*
But you've linked to the wrong firmware for your model.

Hey, a good result!
I'll bet you breathed a sigh of relief.
If your previous NVR firmware didn't have it - check out the 'Forgot password' link on the web GUI login page.
A good feature - worth taking a few minutes to complete those Security Q&As.
