Recording: Option - Swann DIGITAL VIDEO RECORDER Instruction Manual

Recording: Option

Overwrite: When enabled, the DVR will record over the files already stored on the hard
drive. The DVR will always record over the oldest files on your hard drive first. Using
the overwrite option is advisable, as the DVR will always be able to record events as
they happen. However, it does mean that you'll need to get important events off the
hard drive before they're overwritten.
Pre-Record: When enabled the DVR will record for a few seconds before an event
occurs. It is recommended to enable this when using motion detection as your primary
recording method.
Post-Record:
How long the DVR will continue to record after events have taken place.
It can be very useful - for example, if an intruder or potential target triggers the motion
detection but pauses in view. Having this enabled will get a much better look at them.
"Recording: Option"
The menu allows you to change aspects of how
the DVR will record footage such as -
• Whether the DVR will record a short video before events take
place
• How long the DVR will continue to record after events have taken
place
• How the DVR will store and divide long recordings into "packs"
• Whether the DVR will record over old footage to make room for
future events
Pack Duration: This is a measurement of how long the DVR will record for before
splitting the output file into discrete units. "Packs" are something like the chapter
numbers on a DVD - though the video is broken up into separate units, it will still
play through as one continuous movie (unless interrupted by the schedule or motion
detection turning the recording on or off). If you don't want to worry about setting pack
durations, you can leave the default value as it will make little difference to the day-to-
day running of the DVR.
