Record Schedule
The record rate and image size determine the amount of time cameras can be
recorded for and the update rate of each camera. Settings can be applied to
day, night, and weekend schedules. The D4 is capable of supporting a
standard record rate of up to 50/60PPS (PAL/NTSC).

Note: The Night and Weekend options are only displayed if a corresponding
Night and Weekend schedule has been configured in the Schedule menu
page.
Important Information: A record rate of 50/60PPS is achievable with 2
cameras; a single camera will record at a maximum of 25/30PPS.
Standard and Event PPS
Select a record rate in pictures per second (PPS) to be recorded across all
cameras. When a single camera is being recorded, the maximum record rate
is 25PPS for PAL and 30PPS for NTSC cameras. When multiple cameras are
recorded the maximum record rate is 18PPS.
The default record rate is 3PPS, this is the equivalent to a VCR in 48-hour
time-lapse mode. However, because there are only a maximum of 4 cameras
the update rate is faster than a 24-hour time-lapse mode recording 9 or 14
cameras.

To configure D4 to record only events, select the Standard PPS as 0PPS and
the Event PPS to a value you want the events to record at for example, 3PPS.
The D4 will then not record any cameras until activity or alarms are triggered,
it will then record the alarmed/activity camera interleaved with the other
cameras.
Note: Audio is not recorded when the record rate is at 0PPS.

Tip: To work out the update rate per camera - the number of seconds before
the camera is updated. Divide the number of cameras by the record rate
(PPS). For example, 4 cameras with a record rate of 3PPS will be:
Update Rate (seconds) = Number of cameras = 4 = 1.33 seconds
PPS
You can decrease the update rate by increasing the record rate (PPS), the
only drawback is that the recording time will also decrease.
