I have the DS-KV6113-WPE1 (C) doorbell. It has been connected fine with my DS-7204HUHI-K1 / P DVR.

I’ve updated the firmware of the doorbell to add new features as it had a 2022 version.

However I cannot add it now to my dvr. It showed invalid parameter, I tried different things to resolve it but now it says user lock out.

The user and password is correct as I can connect fine with these credentials to the web interface of the doorbell. I waited hours, rebooted both devices but the problem remains.

Any suggestions?
