The GV-Recording Server is a video streaming server designed for large-scale video surveillance deployments. It can receive and record up to 128 channels from various IP video devices. Through an intuitive Web interface, each IP camera can be configured to record video continuously, upon motion detection, upon I/O trigger or according to a schedule.

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-Mobile Server, GV-Control Center (central monitoring system) and Multi View (viewing software). Using the GV-Recording Server, 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-Recording Server 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.

• Simultaneous receiving and recording up to 128 IP channels
• Distributing up to 300 IP channels of video to clients
• Video gateway between IP devices and receiving clients (GV-System, GV-Control Center, GV-GIS, GV-Mobile Server and Multi View)
• Support for third-party IP video devices (Sony, Axis, VIVOTEK, Panasonic, HikVision, Arecont Vision)
• Support for ONVIF, PSIA and RTSP protocols
• Different recording policies to set each channel to record continuously, upon motion detection, upon I/O trigger or by schedule (recording upon I/O trigger is only for GV-IP devices)
• Video playback using Remote ViewLog
• Web interface to remotely configure and monitor GV-Recording Server using Internet Explorer, Firefox, Google Chrome and Safari
• Passive and active connection methods with IP video devices (Passive connection only supported by GV-IP devices)
• Solution for Mobile DVR (GV-Video Server, GV-Compact DVR) to obtain a public IP address
• Bandwidth monitoring
• Two-way audio communication (only for GV-IP devices through active connection)
• Support for 31 languages

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 recommended hard disk requirements for 24 hours of recording are listed as below.

The server's transmitting capacity varies depending on the number of Gigabit connections. The numbers of Gigabit network cards required to receive 128 channels and transmit 300 channels are listed below according to the resolution of the source video.

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