Operating Environment 1 Introduction Important • The system requirements described above are the minimum configuration, assuming the following operating environment: Storage Server Viewer Maximum recording/playback data rate Overall recording frame rate Maximum number of cameras with motion detection *1 Maximum events processed *2 Estimated display frame rate *3 Total number of simultaneously displayable MPEG-4 and H.264 videos 80 Mbps 1280 fps or slower (640 fps or slower when recording audio) 10 20,000 events per day 1280 x 960: 40 fps *4 640 x 480: 80 fps *4 320 x 240: 320 fps 6 or less*5 *1 Number of cameras selected in [Motion Detection Using]>[Storage Server] for motion detection recording. *2 Total number of all types of events. *3 Assumes a standard resolution ([Image Quality] setting is [3]) and that the receive size and display size are the same. If the receive size and display size are different, performance may decrease due to an increase in processing load. *4 If multiple image sizes are combined on a system, the equivalent sizes are four 320 x 240 images for 640 x 480, and eight 320 x 240 images for 1280 x 960. For example: 1280 x 960 (10 fps)  equivalent to 80 fps (10 fps x 8) 640 x 480 (20 fps)  equivalent to 80 fps (20 fps x 4) 320 x 240 (160 fps)  160 fps (same as original)  Total of 320 fps (80 + 80 + 160) *5 The number of videos you can display at once depends on the amount of memory available. If there is not enough memory, you will not be able to display videos. • If you need to operate a high-reliability system (such as for 24-hour operation) in a system environment, we recommend that you use a server operating system on the computer that is used for the Storage Server. • When high-reliability operation is required (such as for 24-hour operation, and high frequency disk access) we strongly recommend that you use a high-reliability SAS hard disk. Using a low-reliability SATA hard disk may result in a disk error in a one to two year period. Therefore, you may need to check the disk for errors on a regular basis, using features such as scan disk. In such a case, recording performance may suffer during checking, due to the increased load on the disk. • With systems intended for users requiring high-reliability/H.264, when operating both the Storage Server and the Viewer on one computer, the operating environment must satisfy the requirements for both the Storage Server and the Viewer. However, to help ensure stable operation, we recommend that you use separate computers for the Storage Server and for the Viewer. 15
