TeleGuard^® 6 Channel Network Video WebServer

The Original Internet WebCam with full Pan, Tilt & Zoom functionality now in it's third generation 

Our TeleGuard® Video Webserver is a stand alone network video server connecting standard analogue video devices such as surveillance cameras to a computer network. Our TeleGuard® Video Webserver has HTTP server and JAVA software embedded for Browser operation. In addition our TeleGuard® Video Webserver has enhanced multi-channel features allowing fast and widespread transmission of live images from all of its 6 video inputs.

Video surveillance has been implemented by many industries to which the benefits of visual monitoring are paramount. By bridging analogue video systems to the digital world, our TeleGuard® Video WebServer is able to bring these benefits to a new arena: computer networks. The result, visual information previously confined to specialist viewing stations, can now be seen on a standard PC across the great expanse of wide-area, or even global, networks. Think about all those LANs, WANs, Intranets, Extranets, phone lines, ISDN lines and even the Internet, already in place and all able to transmit your video.

Using advanced image acquisition, compression and transmission hardware integrated into an all-in-one box solution, our TeleGuard® Video WebServer is able to deliver up to 15 high quality images every second over an Ethernet network to a desktop PC. Alternatively, in a gallery mode, our TeleGuard® Video WebServer can display all of the connected cameras simultaneously and update each camera at 2 images per second.

Our TeleGuard® Six Channel Video WebServer is designed to be simple yet powerful. This means no monitor, keyboard and mouse are required. Our TeleGuard® Video WebServer runs on a real-time multi-tasking operating system providing fully automated operation. A simple box with standard camera and network connections (optional ISDN or PSTN too); just plug in, switch on and go. There’s no costly specialist software to install to see the images either. All you need is a desktop computer running a browser package (we recommend Netscape Navigator or Microsoft Internet Explorer). Type in the address (URL) of the TeleGuard® Video WebServer and the images arrive.

Comprehensive administration utilities are included in the TeleGuard® Video WebServer, providing complete remote control of many video functions and, when fitted, pan-tilt units. Even the network configuration can be changed via the network. In fact, once installed there is no reason to ever attend the TeleGuard® Video WebServer in person again. And just for that little bit extra, our TeleGuard® Video WebServer has two user-operated outputs for activating lights, doors and barriers remotely.

Simply put, with our TeleGuard® Six Channel Video WebServer you can view your video cameras where you want, how you want and when you want.
