2. The Maximum License is a paid service.
Frame Rate Limit in a Single Hard Disk
Since the size of transmitted data from IP cameras may be quite large and reach beyond the transfer rate of a hard disk, you should note the total of recording frame rates that you can assign to a single hard disk, as listed below:
Video resolution H.264 MJPEG
Frame Rate Bit Rate Frame Rate Bit Rate
5MP (2560x1920) 220 fps 8.5 Mbit/s 80 fps 30.4 Mbit/s
4MP (2048x1944) 330 fps 10.4 Mbit/s 105 fps 40.53 Mbit/s
3MP (2048x1536) 440 fps 9.83 Mbit/s 140 fps 38.67 Mbit/s
2MP (1920x1080) 660 fps 12.59 Mbit/s 210 fps 44.93 Mbit/s
1.3MP (1280x1080) 660 fps 6.16 Mbit/s 300 fps 32.26 Mbit/s
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.
