1. It is recommended to use the internal GV-USB Dongle to have the Hardware Watchdog function which restarts the PC when Windows crashes or freezes.
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 resolutionH.264MJPEG
Frame RateBit RateFrame RateBit Rate
5MP (2560x1920)220 fps8.5 Mbit/s80 fps30.4 Mbit/s
4MP (2048x1944)330 fps10.4 Mbit/s105 fps40.53 Mbit/s
3MP (2048x1536)440 fps9.83 Mbit/s140 fps38.67 Mbit/s
2MP (1920x1080)660 fps12.59 Mbit/s210 fps44.93 Mbit/s
1.3MP (1280x1080)660 fps6.16 Mbit/s300 fps32.26 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.
