System Design Maximum System Configuration The following table describes the maximum system configuration supported by this software. Number of Storage Server Groups Number of Storage Servers Number of cameras Number of simultaneously connected Viewers Number of cameras that can be used by a Viewer Number of camera video that can be simultaneously displayed by a Viewer RM Manager 16 16 (1 for each Storage Server Group) 512 units (Maximum number of cameras that can be added to one Storage Server Group is 64 when using RM-64) 12 units 512 units (same as the max. number of cameras) 64 units 1 Determining the Capacity of the Storage Server Refer to "Operating Environment" (P. 14), and configure a system that meets the requirements. Determine the capacity of the storage server based on factors such as the number of recording cameras, video size, video quality, and recording times. Hard disk capacity requirements It is assumed that you use continuous recording at a fixed frame rate (number of frames per second), video size and quality. The size of the recording data varies depending on the camera configuration (video quality and video size settings). Also, the video data size used for calculating the recording data size may vary from the actual video. You can determine hard disk capacity requirements using the Required Disk Space Calculator available on the Canon website. Determine the following factors beforehand when calculating the hard disk capacity. • Number of cameras • Video size, video quality, and frame rate of each camera • Daily duration of recording Note • You can also use the Data Size and Bit Rate Estimates table found on the RM-64/25/9's CD-ROM to perform calculations. Instructions on how to perform the calculations are also included in the table. • The Data Size and Bit Rate Estimates table can also be found on the Canon website. Calculating Network Bandwidth You need to consider the network bandwidth if you want to use a network camera for both recording and live view. You must calculate the network bandwidth both for the Storage Server and the Viewer. For example, calculate the bandwidth as follows if you use one Storage Server (320 x 240 1 fps) and two Viewers (320 x 240 5 fps): (When usingVB-H41) • Bandwidth for recording 10.8 (KB/frame) x 1 (frames/sec.) x 8 (bits) = 86.4 Kbps • Bandwidth for live view (per Viewer) 10.8 (KB/frame) x 5 (frames/sec.) x 8 (bits) = 432 Kbps 28
