This page is about GANZ DVRs (Digital Video Recorder) systems (model numbers coming soon) used for CCTV systems. The storage device used for storing the video footage is a standard Seagate IDE Hard Disk, and inputs from cameras are delivered through BNC connecters, in a composite format.

Remote Access

The DVR has an onboard ethernet controller, which allows it to be connected to a TCP/IP computer network. One of the advantages of doing this is so users can remotely access the live video stream via Microsoft Windows based software, or through the DVR's built in web server. The web server allows the user to receive the stream, through a Java applet embedded into the page.

The Microsoft Windows based software, entitled "Video Server E", can be downloaded here: Click here

Common Faults

You may find that the hard disk size reported on the DVR suddenly significantly decreases, from say 160GB to 7GB. This fault can be easily remedied using the following method to repartition the HDD (please note, all stored footage will be lost):
  • Remove the cover off the DVR
  • Unplug and remove the Hard Disk drive
  • Go to a computer running Windows XP (or above), shut it down and remove the case
  • Plug the hard disk into the computer
  • Power up, and make sure your BIOS reports the new disk.
  • When Windows has booted, go to start, run and type cmd
  • Type diskpart
  • select disk 1 (disk number may be different depending on how many drives connected etc)
  • create partition primary
  • Check for error messages, if none, then it has worked
  • Shut down the computer, remove the HDD and replace it in the DVR
  • Turn on the DVR, make sure the power is not interuppted, it should now format the partition you created.
  • It should now report the correct disk size.
Linux users can use the diskpart or fdisk tool to perform the same task.
DOS users may not be able to use the fdisk tool, as it only supports a maximum of 137GB, this is not a problem if the disk size is under 137GB
