Alarm Setup
Pre-alarm
Pre-alarm images can be recorded for a pre-set time prior to an alarm. Select the
number of minutes or seconds (30 min 59 sec maximum).
Note: Pre-Alarm Recording only occurs if standard recording is taking place.
Post-alarm
Post-alarm images can be recorded for a pre-set time after an alarm. Select the
number of minutes or seconds (30 min 59 sec maximum).
Auto copy
Alarms can be automatically copied to an external Zip® or Jaz® disk.
Global alarm contact
A global alarm contact is used to force all cameras into an alarm condition.
This could be used if one alarm needs to trigger all cameras, or as a panic alarm
operated manually. Options are direct, using the AUX input, or using a specific
contact on an alarm module.
Alarm display
By default, the last alarmed camera is not displayed on the main monitor.
Select ‘Yes’ to display cameras with alarms.
Total video storage
The figure displayed shows the total amount of internal and external disk capacity
available for video storage in GB (Gigabytes).
Earliest recording
The earliest recording displays the date and time of the first image on the disk.
Note: If an event partition is set (in the System Options menu) then the earliest
recording could be an event that is older than the first standard recording.

Recording events only
Digital Sprite 2 can be configured to record cameras with activity or alarm events
only, which can increase the amount of time the hard disk can record for before
being overwritten.
To configure Digital Sprite 2 for event only recording:
1. Set the Standard PPS to 00.
2. Set the Event PPS to the desired record rate when an event is detected.
3. Select the ‘Events active’ option as either Both, Alarms, or Activity as required.
4. Select ‘Event mode’ option as Exclusive to re c o r d only cameras with alarms or activity.
Only activity or alarm events will now be recorded. Note that pre-alarm/activity is
not possible in this configuration.
