VMD Protect Period
Any VMD event can be protected from being overwritten. The protection period can be set as a
number of days or indenitely, ensuring the les are always available. The les will be automatically
overwritten after the congured period has expired.
Note:
Protecting images will reduce the hard disk capacity. This should be taken into account
when specifying hard disk requirements.
VMD Pulse Extension, Pre-Alarm Time and Alarm Duration
The pulse extension extends the trigger period to avoid double triggers of VMD occurring, i.e. If a
second incident of VMD is received, after the rst alarm is nished but within this period, the unit will
not create a new event.
Pre-Alarm Time
This is the period of time, prior to the VMD trigger, that will be included along with the VMD recording
for archive and protected. The unit places a ‘marker’ in the regular recording that acts as the start of
the pre-alarm recording. The number of images available will be dependant on the pre-alarm time set .
Note:
If recording is not enabled, there may not be any images on the disk. If pre-alarm recording
is required, ensure recording is enabled.
Alarm Duration
This is the minimum time period in seconds from the start of the VMD trigger that will be protected
from being overwritten. This time will include the VMD recording, the pulse extension and any post
alarm recording (if applicable). This does not include the pre-alarm images.
Relays
The relays on the unit can be congured to automatically trigger under certain conditions.
Cell Display
It is possible to select whether the Activity, VMD or both (VMD and Activity) cells are displayed on
the main monitor (Mon A). The option can also be disabled.
