Note: The data above was determined using the bit rate listed above and hard disks with average R/W speed above 110 MB/s.
The frame rate limit is based on the resolution of video sources. The higher video resolutions, the lower frame rates you can assign to a single hard disk.
In other words, the higher frame rates you wish to record, the more hard disks you need to install. For the information of recording frame rates, you may
consult the user’s manual of the IP camera that you wish to connect to.
