Overwrite: When enabled, the DVR will record over the les
already stored on the hard drive. The DVR will always record
over the oldest les on your hard drive rst.
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 o the HDD
before they’re overwritten.
Pre-Record: While Pre-Record is enabled, the DVR will record
a few seconds before an event occurs. It’s a little like making
the DVR psychic (but not really - it’s actually just caching a few
seconds of video which it adds to event recordings as they
occur).
If you’re using Motion Detection (recommended) and/or
Alarm based recording as your primary recording method(s),
then it’s a really good idea to use Pre-Record - sometimes, if
an event is fast enough, it might have left view before the DVR
can trigger a recording. With Pre-Record, there’s almost no
chance you’ll miss it.
Post-Record: How long after an event occurs that the DVR
will continue to record. It can be very useful - for example, if
an intruder or potential target triggers the motion detection
but pauses in view; having post-record enabled will get a
much better look at them. 30 seconds is the recommended
length for the post-record setting, but it can be set higher (the
options are 1, 2, 5 or 10 minutes) depending on your unique
circumstances.
Pack Duration: Pack Duration is a measurement of how long
the DVR will record for before splitting the output le 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 o). If you don’t want to worry about setting
Pack Durations, you can leave it on the default value; it will
make little dierence to the day-to-day running of the DVR.
Recording: Option
The Recording: Option menu lets you
change some aspects of how the DVR
will record footage, such as:
• whether the DVR will record a short
video before events take place,
• how long after events take place the
DVR will continue to record for,
• how the DVR will store and divide
long recordings into “packs” and
• whether the DVR will record over
old footage to make room for new
events.
