Post Alarm
Post alarm is the number of seconds the user wishes to record after an event alarm. The choices
are from 0 - 59 seconds.
Screen Rotation
Screen rotation is used to rotate the live image screens. User can set the amount of time in sec-
onds before the screen rotates to the next screen.
Day Light Savings
Day light savings allows the system to be set for daylight savings time. To set up daylight sav-
ings: 1). Select the day light savings check box. 2). Enter the months for the beginning and end
of daylight savings. At the beginning of daylight savings one hour moves forward and at the end
one hour moves backward. The system will mark the saved video table with a “D” during day-
light savings time.
Automatic Rebooting
This allows the user to specify a time to automatically reboot the system. User can select mul-
tiple days and time or single day and time for rebooting the system.
Overwrite Data
By checking this box the system will overwrite existing recorded data when all hard drive space
is used. The system will overwrite the first file and continue in order until the last VDB file is
overwritten. It then repeats the cycle. For information on VDB files, see create VDB in this sec-
tion. When the system begins to overwrite data, it changes the HDD usage bar to display over-
write and the slide indication starts over again.
Create VDB
The DVR uses a state of the art indexing system. When the DVR was manufactured, all data
drives were written with the VDB index. This index creates a fixed file for the system to fill with
recorded data. This file holds both the recorded video and index information. By utilizing the
VDB index, data drives will never get fragmented causing a loss of performance. To create VDB,
click the create VDB button. The VDB create window will open. Note: Extreme caution should
be used when using Create VDB as existing data can be lost. This is preset at the factory and
should not be changed except by an authorized service repairman. Incorrect usage could ren-
der your system inoperable. To add HDD contact your supplier.
