Determining the Capacity of the Storage Server
You must determine the configuration of your Storage Server based on the recording and playback data volume per second
and the required hard disk capacity.
Recording / playback data volume per second and the audio data volume
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.
*The JPEG video frame rate is based on an [Image Quality] setting of [3].
Audio data requires a Storage Server of 64 Kbps, regardless of the type of camera.
Hint
See “System Information” (p. 109) for details on the recording/playback data volume per second during operation.
