My NVR is constantly beeping, I dont have the pattern/password to enter it.

I sent an email with QR code and XML from the SADP tool to support.eu@hikvision.com but I never got a reply.

In the meantime i turned it off because of the constant beeping, then I read it has to stay on.

Did they never reply because it didn't stay on or some other reason? That was a couple of weeks ago.
