Viewer Estimated display frame rate *5 Total number of simultaneously displayable MPEG-4 and H.264 videos When using Intel i7 + GTX 660 For 1920 x 1080 display size: 30 fps (15 fps for H.264)*6 For 1280 x 720 display size: 40 fps For 1280 x 960 display size: 40 fps For 960 x 540 display size: 45 fps For 640 x 360 display size: 80 fps For 640 x 480 display size: 80 fps For 480 x 270 display size: 160 fps For 320 x 180 display size: 320 fps For 320 x 240 display size: 320 fps 6 or less *7 *1 If the volume per second of recording and playback data handled by one Storage Server is 80 Mbps or greater, you should review your recording requirements to ensure system stability. The following shows an estimate of the recording and playback data volume per second for various video formats. JPEG MPEG-4 H.264 320 × 240 810 fps 640 × 480 280 fps 1920 × 1080 50 fps 80 Mbps For standard resolution ([Video Quality] set to [3]), the JPEG video frame rates will result in an estimated data rate of 80 Mbps. Audio data requires a Storage Server of 64 Kbps, regardless of the type of camera. You can check the recording/playback data volume per second during operation on the [Storage Server] tab in RM Manager (P. 54). *2 The data size of recorded audio is calculated using a frame rate of 10 fps per camera. *3 Number of cameras selected in [Detect Motion Using] > [Storage Server] for motion detection recording. *4 Total number of all types of events. *5 Assumes a standard resolution ([Video 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. *6 When multiple video sizes are combined, they will be equivalent to the following: 1920 x 1080 will be equivalent to 14 320 x 240 size videos, 1280 x 720 will be equivalent to 8 320 x 240 size videos, 1280 x 960 will be equivalent to 8 320 x 240 size videos, 960 x 540 will be equivalent to 7 320 x 240 size videos, 640 x 360 will be equivalent to 5 320 x 240 size videos, 640 x 480 will be equivalent to 5 320 x 240 size videos, 480 x 270 will be equivalent to 2 320 x 240 size videos, 320 x 180 will be equivalent to 1 320 x 240 size videos. For example, the following combinations will result in a total equivalent of 320 x 240 at 320 fps. 1920 x 1080, 5 fps  320 x 240, 5 fps x 14 = 70 fps equivalent 1280 x 960, 5 fps  320 x 240, 5 fps x 8 = 40 fps equivalent 960 x 540, 8 fps 640 x 480, 8 fps  320 x 240, 8 fps x 7 = 56 fps equivalent  320 x 240, 8 fps x 5 = 40 fps equivalent 480 x 270, 25 fps  320 x 240, 25 fps x 2 = 50 fps equivalent 320 x 240, 64 fps Total: 320 x 240, 320 fps equivalent (70 + 40 + 56 + 40 + 50 + 64) *7 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. • In a system environment with a large number of cameras and connected viewers and where the number of events that may occur is also likely to be high, the Storage Server must come with the specifications that meet the needs of that environment for stable operation. • If you need to operate a high-reliability system (such as for 24hour 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. Before Use 1 19
