To work out the update rate per camera (the number of seconds before the camera is updated)
divide the number of cameras included in the standard record setting by the selected record rate
(PPS). For example, 16 cameras with a standard record setting of 6PPS will be:
Update Rate (seconds) = Number of cameras/PPS =16/6 = 2.67 Secs
To reduce the time between the camera being updated you will need to increase the record rate
(PPS), or switch to milliseconds where you will specify the time between each image. This will
result in an increase in the number of recorded images, however this will reduce the recording time
available on the internal hard drive.
Events Active
Select whether the alarms and activity are On or Off for day, night and weekend schedules.
Note:
If any of the cameras or zones have been changed so the individual settings (day, night,
weekend) are different to the other cameras within the group then the Events Active option
will display ‘Custom’ to show that the settings are different.
The Standard Record menu will change if the Schedule Rates option within the Record Options
menu is disabled. The day, night and weekend settings will be replaced with Rate setting which will
allow permanent xed rates to be set for the standard record rate and the event record rate.
Note:
This also applies to the Variable Record Schedule.
Event Mode
This allows exclusive or interleave recording to be selected within any of the operating modes (Day,
Night, Weekend) and used to adjust the record sequence when an alarm is received. The options for
event recording are:
Unchanged – This sets the record sequence to remain the same whether an alarm is present or not.
Exclusive – The unit will only record the alarm cameras.
Interleaved – This will set the unit to record the alarm cameras more frequently than non-alarm
cameras, by interleaving the two i.e. if camera 1 is in alarm the interleave recording would
be 1213141516…
Note:
By using event interleave, it is possible to keep the record rate constant but effectively
increase the speed of alarm or activity recording.
