For the users of 64-bit Windows, the memory limit of GV-NVR is 1.7 GB with 2 GB RAM and 3 GB with 4 GB RAM. If the high memory issue persists, the GV-NVR will become unstable. 2.To apply GPU decoding, the recommended RAM for 64-bit OS is 8 GB or more, for 32-bit OS is 4 GB. 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 MJPEG H.264 MPEG Frame Rate Bit Rate Frame Rate Bit Rate Frame Rate Bit Rate 2560x1920 (5M) 30 fps 102.26Mbit/s 240 fps 21.24Mbit/s - - 2560x1600 (4M) 60 fps 73.49Mbit/s 240 fps 15.28Mbit/s - - 2048x1536 (3M) 60 fps 64.73Mbit/s 480 fps 10.52Mbit/s - - 1600x1200 (2M) 120 fps 41.16Mbit/s 480 fps 9.16Mbit/s - - 1280x960 (1.3M) 200 fps 30.04Mbit/s 480 fps 5.77Mbit/s 480 fps 6.30Mbit/s 640x480 (VGA) 480 fps 11.42Mbit/s 640 fps 2.54Mbit/s 640 fps 3.27Mbit/s 320x240 (CIF) 480 fps 5.16Mbit/s 640 fps 0.75Mbit/s 640 fps 1.03Mbit/s Note: The above data was determined using the bit rate listed above and hard disks with average R/W speed above 80MB/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.
