Recovering password on Dahua NVR

[JPmedia]

Want to add my other Dahua NVR5216 to the system, but I cannot remember the password I assigned to it when I initialized and updated it last year. Any ideas how to either recover the password or reset it?

Once again - after all, there was already a discussion about this last year.

Look for the 1 and 2 contacts and without power connect them with a jumper cable and then provide power and once the NVR powers up, remove the cable.

Unfortunately, the board on this NVR5216-16P-4KS2 is different. But I was able to get the answers to the security questions by contacting the seller. I was able to set a new password and do a factory reset.

I'm feeling a little under the weather today, and tired Now that it is reset, I will mess with it when I feel better

And there was already some discussion that if the NVR doesn't have an external reset button, it can presumably only be reset by connecting two pins on the motherboard.

That was a different NVR. The NVR I am wanting to use is a NVR5216-16P-4KS2E, so I believe it has the hard reset button. Does resetting the NVR put it back to the original firmware version? The original firmware version was in the 3's and I updated it in steps to version 4

No, normally the firmware version currently installed on it remains intact.

Before going for the reset button, try the local route first: connect a monitor and mouse to the NVR, click Forgot password on the login screen and see what it offers. If you set a reserved email or security questions when you initialized it last year, you can reset the admin password from there without losing any settings. The email option shows a QR code, and scanning it (the DMSS app has a password reset tool for this) gets a security code sent to that reserved email.

If you do end up using the hard reset, plan to redo the channels, recording schedules and network settings, since those get wiped even though the firmware stays. Also worth knowing: cameras the NVR initialized on its PoE ports usually got the same password as the NVR, so if they show up as wrong password after the reset, that is why, and they may need a reset too.
