Optimization of Motion Detection Recording (Index)
226
The Motion Detection recording is not suited to applications where high levels of reliability
are required. Therefore, it is recommended to use continuous recording for monitoring or
other purposes if consistently high levels of reliability are required. Canon accepts no
liability whatsoever for faults, etc. resulting from the use of the Motion Detection recording.
Frequent motion detection events result in high CPU load on your PC, and the recording
frame rate may be reduced or recording may be interrupted. If you have 10 or more motion
detection events per minute continuously, we recommend continuous recording.
Frame Rate indicates the number of frames for Motion Detection recording. Lowering this
value mitigates load on the Storage Sever.

Motion Detection Setting for Each Camera Model
VB-C60, VB-C50i/VB-C50iR, VB-C50FSi, VB-C50Fi, VB150
Configure the Motion Detection settings on the Camera Server.
Please refer to the Camera Server User’s Manual for details.
For the VB150, Video Input must be set to Single.
VB-C300
Configure the Motion Detection settings on the Storage Server.
Refer to “ Setting Motion Detection Recording ” (
➝
P. 124) for details on how to set the
Motion Detection parameters.
Typically, set the total frame rate to 150 fps (e.g., 30 fps with five cameras) with the display
resolution of QVGA.
Longer before event recording with insufficient memory may
lead to the use of disk-based virtual memory which will greatly
reduce performance. Shorter before event recording will
reduce memory usage.
The full requested duration of post event recording may not be
available due to data size and network delays.
