1.5 Installing GV-VMS

Before You Start

For optimal performance of your system, it is important to follow these recommendations

before installing the GV-VMS:

• It is strongly recommended to use separate hard disks. One is for installing Windows

OS and GV-VMS software, and the other is for storing recorded files and system logs.

• When formatting the hard disks, select NTFS as the file system.

• GV-VMS is a multi-channel video recording system. With normal use of the system, the

drive containing video files will become fragmented. This is because GV-VMS

constantly stores video files of multi channels simultaneously, and video files will be

scattered all over the drive. It is not necessary to regularly perform disk defragmentation.

Since GV-VMS software and video files are stored on separated hard disks, the

performance of GV-VMS will not be affected.

• 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:

Frame rate limit in a single hard disk

H.264 MJPEG

Video Resolution

Frame Rate Bit Rate Frame Rate Bit Rate

1.3 MP (1280 x 1024) 660 fps 5.05 Mbit/s 300 fps 32.26 Mbit/s

2 MP (1920 x 1080) 660 fps 7.01 Mbit/s 210 fps 44.93 Mbit/s

3 MP (2048 x 1536) 440 fps 10.48 Mbit/s 140 fps 38.67 Mbit/s

4 MP (2048 x 1944) 330 fps 11.65 Mbit/s 105 fps 40.53 Mbit/s

5 MP (2560 x 1920) 220 fps 16.48 Mbit/s 80 fps 30.4 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.
