When an event is triggered it is automatically interleaved with the non-event
cameras, i.e. if camera 1 has an event, the recording sequence would be
121314121314 rather than the standard sequence of 12341234, effectively
increasing the record speed of camera 1.
Tip: By using event interleave, it is possible to keep the record rate constant but
effectively increase the speed of alarm or activity recording.
Recorded file size
The file or image size affects the quality of the images recorded to disk. A larger
file size has superior picture quality, but will fill the hard disk faster, so less time
will be recorded before the images will be overwritten.
The file size can be set between 6 and 45KB. The table below shows the image
quality at typical file sizes:
Approximate image quality
VHS
S-VHS
S-VHS+
Note: The equivalent image quality is representative in most circumstances,
however, camera views with large amounts of image detail may require the file
size to be increased to obtain a similar image quality.
Maximum recording time
The maximum recording time is the number of days and hours before the images
are overwritten. The maximum record time is calculated automatically when
the standard or event record rate is highlighted and changed.
Tip: Reducing the file size (KB) or record rate (PPS) can increase the maximum
recording time.
Main storage (protected%)
The total video storage in Gigabytes (GB) is displayed along with the percentage
of video storage which is protected (will not be overwritten). Note that the
calculations for recording time assume there is no protected video. Video that is
protected will need to be manually unprotected in the 'Record Options' before it
can be used for recording again.
Earliest recording
The earliest recording displays the date and time of the first image on the disk.
