On the recording: Option page, you may
set
• Whether the NVR will record a short
video before events take place,
• how long after events take place the
NVR will continue to record
• how the NVR will store and divide
long recording?
• Whether the NVR will continue to
record and cover the earliest
recording.
Overwrite: When enabled, the NVR will record over the files already stored on the hard drive. The NVR
will always record over the earliest files on your hard drive.
Pre-Record: While Pre-Record is enabled, the NVR will record a few seconds before an event occurs.
If you’re using Motion Detection (recommended) based recording as your primary recording method(s),
then it’s a really good idea to use Pre-Record.
Post-Record: How long after an event occurs that the NVR 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 of the event.
Pack Duration: Pack Duration is a measurement of how long the NVR will record 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.
