Recording Quality
The DigiMux scheduling items on the Record menu, Night, Day, and Weekend, allow
you to select recording quality for normal and event recording. These menu items are
accessible when you select OFF for Preset Configuration. Recording quality is
associated with the compression of the image as it is stored on your drive. See
About
Image Quality on page 5 for an introduction to recording quality concepts.
There are five different record quality settings: Superior, High, Medium, Standard, and
Basic. Each of these quality settings is described in the following table:
NOTE: Record duration times are based on actual tests. Performance may vary
depending on specific installations and use. File sizes are averages and
actual file sizes may vary, depending on factors such as scene complexity.
Audio recording adds 8 KB per second to the file size.
QUALITY
SETTING
DESCRIPTION
Superior This setting provides the best quality video recording. Use this setting
if you are most concerned about details of the images and least
concerned about the record duration. The average file size is
28
KB NTSC (33 KB PAL).
Superior is used with the Best Quality preset configuration setting.
Best Quality is the default preset configuration setting.
High This setting provides acceptable image quality, but not as good as the
Superior setting. Use this setting for satisfactory recorded images and
increased record duration. The average file size is 19
KB NTSC
(22
KB PAL).
Medium,
Standard,
Basic
These settings do not provide a high level of detail in images recorded,
but recording duration is increased. Use one of these settings when
your concern is primarily extended recording duration, not image
detail. The average file sizes for these selections are:
• Medium, 15 KB NTSC (18 KB PAL)
Medium is used with the Standard preconfiguration setting
• Standard, 12 KB NTSC (14 KB PAL).
Standard is used with the Extended Record preconfiguration
setting.
• Basic, 10 KB NTSC (12 KB PAL)
