Operation and Management Optimization of Motion Detection Recording (Index) 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. Tip z 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. z The full requested duration of post event recording may not be available due to data size and network delays. Motion Detection Setting for Each Camera Model VB-C500VD, VB-C500D, VB-C60, VB-C50i/VB-C50iR, VB-C50FSi, VB-C50Fi, VB150 Configure the Motion Detection settings on the Camera Server. Please see 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. See "Set Motion Detection Recording" ( P. 4-46) 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. 6-7
