- Video server
A video server is a computer based device (also called a 'host') dedicated to delivering video online. Unlike PCs or Macs, both being multi-application devices, a video server is designed for one purpose; provisioning video. A professional grade video server records, stores, and plays back multiple streams of video without any degradation in the video signal. Broadcast quality video servers often store hundreds of hours of MPEG-2 compressed video, play out three or more simultaneous streams of video, and offer quality interfaces such as SDI for digital video and XLR for balanced audio.
In the TV broadcast industry, a server is a used to store broadcast quality images and allows several users to edit stories using the images they contain simultaneously.
The video server can be used in a number of contexts, some of which include:
*News: providing short news video clips as part of a news website (such as CNN).
*Instruction: delivering course material in video format.
*Public Access: delivering city specific information to residents over a cable system.
*Surveillance: deliver real-time video images of protected sites.
*Entertainment: deliver film trailers or music videos.and many more.
IP Video Servers in Video Surveillance
In the surveillance context, an IP video server converts analog video signals into IP video streams. The IP video server can stream digitised video over IP networks in the same way that an
IP Camera can. Because an IP Video server uses IP protocols, it can stream video over any network that IP can use, including via a modem for access over a phone orISDN connection. With the use of a video server attached to an analog camera, the video from an existing surveillance system can be converted and networked into a new IP surveillance system.In the video security industry a video server is a device to which one or more video sources can be attached. Video servers are used to give existing analog systems network connectivity. Video servers are essentially transmission/ telemetry / monitoring devices. Viewing is done using a web browser or in some cases supplied software. These products also allow the upload of images to the internet or direct viewing from the internet. In order to upload to the internet an account with an ISP (internet service provider) may be required. Manufacturers of video servers [http://www.sourcesecurity.com/browse-all/video-servers/make.html] include well known names in the global security industry such as Sony, Honeywell Security, Bosch Security, Axis Communications and Videor Technical.
Contact your service provider regarding FTP (file transfer protocol) and static IP requirements. There are also [http://www.ipcamerasupply.com/index.php?cPath=510 video servers] that do not require static IP.
