Good day, there is a DVR SV Plus R704, it loads when connected, but the standard administrator password - 123456 is not suitable. There is root access via telnet.
In this connection, there is a question - is there a way to reset the DVR password through telnet access, or maybe some other way?
And is there any firmware on SV Plus R704 (original or from compatible models of DVR)?
