These units are high-speed switches that provide full-screen images from up to 16 cameras. Multiplexers can playback everything that happened on any one camera without interference from the other cameras on the system. Network camera - Cameras are attached through an Ethernet connection (or router) and power source, so you don't need a computer at each location you want monitored. Each camera has a built-in web server with IP address. To view the images on a PC, simply open a graphics-capable Web browser and type in the cameras specified, password optional Internet address. No terms are yet available for this letter. PING - Loosely translated, ping means ‘to get the attention of' or ‘to check for the presence of' another party online. Ping operates by sending a packet to a designated address and waiting for a response. The computer acronym was contrived to match the submariners' term for the sound of a returned sonar pulse.
