Appendix

A. Hard Disk Requirements
The total of recording frame rates that you can assign to a single hard disk is listed as below:

330 fps
12 MP
8 MP 660 fps
5 MP 220 fps
4 MP 330 fps
3 MP 440 fps
2 MP 660 fps
1.3 MP 660 fps
Note: The above data was determined using the bitrate listed above and hard disks with
average R/W speed above 110 MB/s.
B. Total Frame Rate and Max. No. of Channels Supported
Below are the total frame rates GV-Tower NVR/VMS System V2 (Rev. C) can support with
CPU usage of approximately 70% to ensure performance and stability. You could connect up
to 32 cameras to the system. See the below charts to calculate frame rate for connected IP
cameras.
For instance, if you connect 8 units of GV Fisheye 12 MP cameras to GV-Tower VMS System
V2 (Rev. C) supporting CPU Intel Core i5 Processor, you will receive 15 fps for each channel
(120 fps / 8 units = 15 fps).
