5 Routine Checks
Although the system is intended for continuous un-attended operation, it is recommended that the user
regularly check that images from all cameras replay correctly. Any potential problems with the cameras
or recording system will then be detected as soon as possible, rather than continuing un-noticed until a
critical incident needs to be recalled from the system.
Similarly, when a CD has been created you should check that it plays back correctly, before the
images are over-recorded on the VDM. The CD may be checked by either by playing it on a VDM or on a
PC.
If a red “Critical Alert” message appears on the screen, this indicates to the user that a fault condition has
been automatically detected that could affect recording. The nature of the alert should be checked in the
events screen and appropriate action taken.
5.1 Critical Alerts
The VDM constantly monitors the hard drive, camera inputs and system so that detected fault conditions will
be reported to the user as soon as possible by means of a “critical alert” message on the screen. Alerts are
also added to the event list.
Press the EVENTS key to view the event list (pressing the DEFAULT key automatically scrolls to the most
recent events.
Viewing the list will cancel the alert message. However if the condition persists, the message will re-appear.
• FailTest
This alert indicates that the system self-test has failed.
o Press
ALT and SETUP to call up the System Information screen. The positions of any solid
blocks displayed on the “Self Test” row indicate various fault conditions.
o Try power cycling the VDC to see if the problem is fixed, or failing this.
o Try a power-on reset (See section Error! Reference source not found.).
o If the problem persists, contact your supplier.
• VidLoss
This alert means that video has been lost on one or more of the camera inputs.
o Make sure that the video loss setting in the menu (see section Error! Reference source
not found.) corresponds with cameras actually fitted.
o Check connections to all cameras.
o Check that each camera can be viewed in live, full screen mode.
o Swap a camera input that is working with the one that is not. Does the problem move with
the camera (i.e. faulty camera or cable) or stay with the input (possible faulty VDC)
o If a camera is suspected as being faulty, connect it directly to a monitor to test it.
• 1 Fail
This alert indicates that a hard drive is not working.
o Check that the drive drawer is correctly fitted
o Check the lock in the drive drawer is turned full counter-clockwise
o Check the
DISC ACTIVITY LED is flickering (see diagram in section Error! Reference
source not found.)
o Check that the green
FAN1 OK and FAN2 OK LEDs are lit.
o Check that the red
DISC POWER led it lit.
• 1 SMART This alert indicates that a hard drive may stop working soon
The SMART monitoring detects imminent failure of a hard drive, so if this warning occurs, the drive should
be changed at the earliest opportunity.
