The GV-Video Gateway is a video streaming server designed for large-scale video surveillance deployments. It can receive up to 128 IP cameras from various IP video devices. In addition, it can simultaneously distribute up to 300 channels to its clients which include GV-System (DVR/NVR system), GV-GIS (geographic information system), GV-Control Center (central monitoring system), and Multi View (viewing software). Using the GV-Video Gateway, the desired frame rates can be reached while the CPU loading and the bandwidth usage of IP video devices are significantly reduced.

Note: The arrows in the diagram indicate the direction of the connections.

In some areas or countries, you may like to install 3G wireless Internet module (e.g. GPRS/UMTS) on the GV-Video Server or GV-Compact DVR but have the problem to obtain a public IP address from ISP. The Passive connection method of GV-Video Gateway can solve the public IP issue by accepting the connection request from the GV-Video Server or GV-Compact DVR, and then distribute the video streaming to clients.

It is also possible to view single-channel live images on the GV-Video Gateway server or multiple-channel live images on any PC through the GV-Video Gateway's Web interface.

It is required to insert the GV-USB Dongle to the server to enable the GV-Video Gateway software. The GV-USB Dongle supports connection with 128 IP channels and comes in two types, internal and external dongles. The dongle enables both GV-IP video devices and third-party IP devices.

• Video gateway between IP cameras and receiving clients (GV-System, GV-GIS, GV-Control Center, GV-IP Matrix and Multi View)
• Maximum video distribution for large IP camera counts (up to 128 IP cameras) and receiving clients (up to 300 IP cameras)
• Passive and Active connection methods with IP video devices (Passive connection only supported by GV-IP devices)
• Compatibility with a variety of third-party IP video devices (Sony, Axis, VIVOTEK, Panasonic, HikVision, Arecont Vision)
• Single-channel or multi-channel live view through IE browser
• Bandwidth monitoring
• Two-way audio communication (only for GV-IP devices through active connection)
• Solution for Mobile DVR (GV-Video Server, GV-Compact DVR) to obtain a public IP address
• Web interface to remotely configure and monitor GV-Video Gateway using Internet Explorer, Firefox, Google Chrome and Safari

Servers meeting the minimum system requirements have the capacity to receive up to 128 channels and transmit up to 300 channels with the image settings of 1280 x 1024 resolution, 30 fps and H264 / MPEG4 codec for each channel.

Servers meeting the optimal system requirements have the capacity to perform one of the following:

• Receive up to 128 channels and transmit up to 300 channels with the image settings of 1280 x 1024 resolution, 30 fps and JPEG codec for each channel. OR
• Receive up to 128 channels and transmit up to 128 channels with the image settings of 1920 x 1080 resolution, 30 fps and JPEG codec for each channel. OR
• Receive up to 128 channels and transmit up to 128 channels with the image settings of 2048 x 1536 resolution, 20 fps and JPEG codec for each channel. OR
• Receive up to 128 channels and transmit up to 300 channels with the image settings of 1280 x 1024 or 1920 x 1080 resolution, 30 fps and H.264/MPEG4 codec for each channel. OR
• Receive up to 128 channels and transmit up to 300 channels with the image settings of 2048 x 1536 resolution, 20 fps and H.264 codec for each channel.

The server's transmitting capacity varies depending on the number of Gigabit connections:

• One (1) Gigabit connection: Transmits up to 75 channels with the image settings of 1280 x 1024, 30 fps and JPEG codec for each channel.
• Two (2) Gigabit connections: Transmit up to 150 channels with the image settings of 1280 x 1024, 30 fps and JPEG codec for each channel.
• Three (3) Gigabit connections: Transmit up to 225 channels with the image settings of 1280 x 1024, 30 fps and JPEG codec for each channel.
• Four (4) Gigabit connections: Transmit up to 300 channels with the image settings of 1280 x 1024, 30 fps and JPEG codec for each channel.

The deployment of Gigabit connections for transmitting and receiving is suggested as illustrated below. Ensure to run every Gigabit connection on a different network to reduce the lag on any network connection.
