The GV-NVR (Network Video Recorder) records video and audio data over TCP/IP networks. With up to 32 channels of pure IP surveillance, the GV-NVR offers the same functions as GV-Series Surveillance System. With additional license, GV-NVR supports up to 32 channels of third-party IP devices. From monitoring features to video analytics as well as integration with LPR, POS/ATM and Access Control systems, it stands as one of the most comprehensive IP surveillance software in the security market.

Combined with GeoVision IP camera, the GV-NVR takes advantage of a better image quality thanks to the progressive scan technology and allows advanced video features such as Picture-In-Picture and Picture-And-Picture. Compatibility with a wide range of third party IP cameras through ONVIF and PSIA makes the GV-NVR the ultimate solution for pure IP surveillance environments.

Built upon comprehensive and easy-to-integrate hardware and supporting technologies, the GV-Surveillance and Video Management Platform is the core system platform that provides performance-optimized video monitoring and various advanced video analytics/control features to support many of enterprise's management functions. It is a scalable, extensible platform that can be customized and seamlessly integrated with other security system applications, such as:

  1. POS/ ATM/ EAS for loss prevention
  2. Access Control for building automation
  3. License Plate Recognition system for law enforcement, entrance control and revenue collection
  4. Megapixel IP devices for critical area and mobile object monitoring
  5. Central Monitoring stations for high profile security areas in commercial, industrial and residential markets

In addition the remote management WebCam and versatile storage system framework offer high scalability and extensibility for future integration with other functions or systems at remote sites.

To obtain the maximum frame rate possible, please see the GPU Decoding Specifications below.

1. For the users of 32-bit Windows, the memory limit of GV-NVR is 1.7 GB with 2 GB RAM. 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. GV-System has ended support for Windows XP and Vista.
3. For users of earlier versions of Windows, you need to install the DVR V8.7 patch file.
Software License
32 channels from GV-IP devices
32 channels from third-party IP devices
1 to 32 third-party IP cameras at an increment of 2
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.
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 H.265 MJPEG
Frame Rate Bit Rate Frame Rate Bit Rate Frame Rate Bit Rate
12MP 330 fps 14.47 Mbit/s N/A N/A 56 fps 65.98 Mbit/s
8MP 660 fps 14.13 Mbit/s N/A N/A 96 fps 58.52 Mbit/s
5MP 220 fps 8.5 Mbit/s 660 fps 6.73 Mbit/s 80 fps 30.4 Mbit/s
4MP 330 fps 10.4 Mbit/s 550 fps 7.74 Mbit/s 105 fps 40.53 Mbit/s
3MP 440 fps 9.83 Mbit/s 660 fps 5.35 Mbit/s 140 fps 38.67 Mbit/s
2MP 660 fps 12.59 Mbit/s N/A N/A 210 fps 44.93 Mbit/s
1.3MP 660 fps 6.16 Mbit/s N/A N/A 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.
GPU Decoding Specifications
A higher total frame rate can be achieved if your CPU or on-board VGA supports GPU decoding.
On-board VGA: GPU decoding is only supported when using the following Intel chipsets:
For H.264 Video Compression
• 2nd Generation Intel Core i3 / i5 / i7 Desktop Processors (Sandy Bridge) - only support 1 MP to 2 MP videos
• 3rd Generation Intel Core i3 / i5 / i7 Desktop Processors (Ivy Bridge)
• 4th Generation Intel Core i3 / i5 / i7 Desktop Processors (Haswell / Haswell Refresh)
• 6th Generation Intel Core i3 / i5 / i7 Desktop Processors (Skylake)

For H.265 Video Compression
• 6th Generation Intel Core i3 / i5 / i7 Desktop Processors (Skylake)
1. If you have both on-board VGA and external VGA installed, the on-board VGA must be connected to a monitor for H.264 / H.265 GPU decoding.
2. You can install multiple external graphics cards if needed.
Total frame rate and number of channels supported
Refer to the documents below to see the total frame rate and number of channels supported by GV-DVR when connected to GV-Fisheye cameras and H.265 cameras.
