Troubleshooting 188
11. Problem:
The unit does not record video even though it is configured to do so, or video that was
recorded by the unit cannot be accessed by any of the client applications.
Solutions:
• In the
System Diagnostics screen (or the System screen), check the HD Size and HD
Model. If the size is 0 or the model is incorrect, there may be an internal hard-drive
problem. Contact your vendor.
Additional information: System Statistics, page 174
• Ensure that the unit time and the time zone are correct.
Additional information: Setting the Unit Time, page 57
• In the
System Diagnostics screen, check the System Clock status. If the status is
“Error,” try resetting the clock manually. If that does not solve the problem, contact
technical support.
Additional information: System Statistics, page 174; Setting the Unit Time, page 57
• Ensure that daylight savings time is configured in the same way on the PC from
which you are connecting to the MVG 400 and on the MVG 400.
Additional information: Setting the Unit Time, page 57
• If you have configured the unit for event-triggered recording, ensure that at least one
sensor is selected as a trigger, that the selected sensors are functioning properly, and
that one or more of the sensors detected events during the time period from which
you attempted to view recorded video.

12. Problem:
The unit is connected to a LAN but cannot be accessed through the LAN.
Solutions:
• Ensure that the Ethernet (network) cable is fully inserted into the Ethernet (Out)
connector on the rear panel of the MVG 400 unit.
Additional information: Connecting the MVG 400 to an External Network, page 26
• Check whether the LEDs on the rear panel of the unit (in the upper-right corner) are
blinking. If they are not, replace the Ethernet cable.
• Ensure the short Ethernet cable connecting the video gateway component of the
MVG 400 to the unit’s router is properly inserted into both connectors (the top-most
Ethernet connector on the right and the connecter Ethernet connector immediately
below it).
• If both Ethernet cables are functional and properly inserted into their connectors but
the LEDs on the rear panel of the unit are not blinking, contact technical support.
