3R Max DVR Info and Ethernet FTP Telnet login

The 3R MAXDVR4000 is a 1U rackmount DVR with four composite inputs.

There is not much info out there about them, there are two IDE hard drives inside formatted with resizerfs, a Axis Video Controller serial and Ethernet port.

If there hard drives are no longer working, they can be removed and replaced with another pair of working drives.  The sizes do not have to match either.  The drives are formatted and file and folder structures are copied on to the new hard drives upon power up.  You may notice a file called 'Hdd_Image.tgz' copied on one or both drives, containing the default info.

Conducting a Wireshark trace on the Ethernet port, yielded a default static IP of 192.168.0.60, with a Telnet and FTP server.

Default login credentials are:
root
pass

Default front panel password is 0000
 

Files can be easily pulled from the unit using FTP and the unit work in a circular buffer mode.
