INTRODUCTION

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. Then 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). Through the GV-Video Gateway, the CPU loading of IP video devices is significantly minimized and the desired frame rates are reached as well as the bandwidth usage is greatly reduced.

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.

• 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
• Compatibility with a variety of third-party IP video devices
• Single-channel or multi-channel live view through IE browser
• Bandwidth monitoring
• Two-way audio communication (only for General Hosts)
• Solution for Mobile DVR (GV-Video Server, GV-Compact DVR) to obtain a public IP address
• Web interface for live image monitoring, multicast streaming and event log query

The server conforming to the minimum system requirements has the capacity to perform one of these:

• Receive up to 128 channels and transmit up to 300 channels with the image settings of 1280 x 1024 resolution, 15 fps and MPEG4/H.264 codec for each channel. OR
• Receive up to 128 channels and transmit up to 300 channels with the image settings of 640 x 480 resolution, 30 fps and MPEG4/H.264 codec for each channel.

The server conforming to the minimum system requirements has the capacity to perform one of these:

• Receive up to 128 channels and transmit up to 104 channels with the image settings of 1280 x 1024 resolution, 15 fps and JPEG codec for each channel. OR
• Receive up to 128 channels and transmit up to 184 channels with the image settings of 640 x 480 resolution, 30 fps and JEPG codec for each channel.

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

• One (1) Gigabit connection: Transmits up to 104 channels with the image settings of 1280 x 1024, 15 fps and JPEG codec for each channel.
• Two (2) Gigabit connections: Transmit up to 256 channels with the image settings of 1280 x 1024, 15 fps and JPEG codec for each channel.
• Three (3) Gigabit connections: Transmit up to 300 channels with the image settings of 1280 x 1024, 15 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.
