The higher the record quality, the higher the bit rate and the size of the event files. The
default setting is Very High for maximum video quality, but can be lowered to Standard
or High to increase the compression rate and reduce the required storage space (see
Figure 3-8).
Settings: Standard, High, and Very High [default]
FPS (Record Frames Per Second)
Sets the number of frames per second the DVM will record. The higher the setting, the
better the video quality, and the larger the size of the event files.
Settings: 5FPS, 10FPS, 15FPS, 30FPS [default]

File size varies with the Record Quality, FPS settings, and video content.
Consult the table above to determine which settings are best for your
application. The data above was extrapolated from 1 minute video file
samples, and were focused on a stationary background. This is intended as a
general guideline and actual compressed video size will vary based on subject
matter.
Event Audio
The Event Audio setting determines how audio will be recorded to your DVM. If
“Enabled” , audio is recorded both during the recorded event and during the configured
pre-event buffer time. If “ Enabled (w/o Pre-Event) ”, audio will be recorded during the
event but not recorded during pre-event. If “Disabled” , no audio will be recorded. If the
Pre-Event Buffer Time is set for 0, Pre-Event Audio is turned off.
Settings: Enabled [default], Disabled, Enabled (w/o Pre-Event)
Pre-Event Buffer Time
This option allows you to set the amount of time for the pre-event buffer, in 6 second
increments. If enabled, the DVM will buffer the last 6-30 seconds of video prior to the
start of the recorded event so that it can be recorded as part of the event. A setting of
“0 second” disables the pre-event function and removes the “Enabled (w/o Pre-Event)”
audio setting from the Event Audio dropdown menu.
Settings: 0, 6, 12, 18, 24, 30 seconds [default]
