Set Sensor Event Recording
If the before and after event fields are set to 0 seconds, video
will still be recorded while the sensor is activated.
Longer pre-event recording will increase memory usage.
Longer pre-event recording with insufficient memory may
greatly reduce performance when the disk-based virtual
memory runs short.
Note
The frame rate specified is the frame rate that the Storage
Server will attempt to record, and may not be the actual frame
rate used for recording video. Factors such as the number of
Viewers, the number of Camera Servers used, network traffic
and load on the Camera Server and the Storage Server may
reduce the actual frame rate recorded.
While the resolution is set to MEPG-4, the frame rate drop-
down menu is gray out. However, the video is recorded at the
frame rate specified in the VB-C60 setting page at that point.
Note
Record for before event - enter a number of seconds for the amount of recording
time before the event occurs (up to a maximum of 30 seconds).
Record for after event - enter a number of seconds for the amount of recording
time after the event has transpired (up to a maximum of 999 seconds).
Click OK to save the new settings and close the dialog.
Click Cancel to discard the new settings.

If Continuous Recording is also set, Record for before event is
not available.
If Record for before event is set, it will take approximately 10
seconds after event occurrence until its display in the viewer.
