1.3 Recording
The Ai150 Digital Recorder should now be fully operational and recording images from all
cameras. The default image retention period is 31 days.
1.4 Routine Checks
If the Ai150 is
not
recording, the message
STOP
will be displayed on top right of the video
monitor. This should only happen if no hard drive is fitted or if it is faulty.
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 a
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 on the hard drive in the Ai150 become over-written. The CD may be
checked by either by playing it on the Ai150 or on a PC.
1.5 Care of the Hard Drive
The hard drive is a delicate mechanical item that should be handled with care. Before
moving a Ai150 that has been powered up, remove power and
wait for 30 seconds for the
drive to stop spinning
. This is a precaution to avoid possible damage to the hard drive.
