Pelco Manual C680M-G (7/01) 17

RECORDING EXAMPLE
A company has a rear door that is not to be opened for any reason between 5 p.m. and 7
a.m. During the day, the area around this door is recorded continuously (scheduled record-
ing), but to conserve disk space, the area is only recorded at night if the door is opened
(event recording).
In this case, the recorder would be programmed for scheduled (continuous) recording from
7 a.m. to 5 p.m. and event recording from 5 p.m. to 7 a.m. (refer to
Camera Menu
in the
Programming
section).
SAVING VIDEO
When the hard disk drive is full, the DVR starts to overwrite the oldest data. Refer to Table
C to determine approximately how much data can be stored on the hard disk drive and
when you should back up your data. Data should be backed up on a regular basis to en-
sure that important video is not lost.
NOTE:

Turning off cameras does not save video for those cameras. All that does is

provide more disk space to record other cameras. When the hard disk drive is full, the

DVR will start overwriting the oldest video recorded.

To save video:
1. Connect a peripheral recording device, such as a VCR or video printer, to the PHOTO
PRINTER connector on the rear of the DVR.
2. Turn on the peripheral recording device. If the DVR is in the record mode, the video
also will be recorded on the peripheral device. If the DVR is in the playback mode, the
video will be recorded on the peripheral device.

The recording times in Table C depend on the file size for each recorded picture. The file
size can vary with the scene, amount of motion, and other factors. The figures in Table C
represent the average recording times and do not guarantee recording times in a particular
application.
NOTE:

Values indicating video storage capacity are estimates only. These estimates

are to be used as guidelines in determining proper hard drive requirements. Many

user selectable factors such as image quality, recording rate, image content/motion,

and video noise will all affect the total amount of video that can be stored on a hard

drive. These video storage duration estimates will vary based on actual use. These

estimates are not an implied or expressed guarantee of actual performance.
