Hello hobby friends,

I braced a DS-7732ni-i4/24p NVR at a bankruptcy auction
but I don't have a password so it needs to be reset.
I can see in SAPD and in IVMS4200 that he is active in the range 10.29.76.30
and my router has the range of 192.168.2.1.

How do I reflash it and put a new firmware on it.
There are several possibilities

1. If you want to make a password reset request, it is highly recommended to scan the QR code to download the Hik-Partner Pro app and follow the to make a request.

2, If you can't make the phone on which the Hik-Partner Pro app and the Hikvision device are installed on the same LAN, click here to reset the password as the video 4 Ways to Free You from Password Reset

With TFTP server and a serial cable or are there any other tips
That would be my choice of method.

You'd need an RS232 (not TTL serial) interface, probably with a null modem cable, to connect to the DB9 connector on the back panel.
And a normal tftp server such as this one :

And a serial terminal program such as PuTTY
