kensplace 0 Posted November 9, 2006 A matrix basically is used for larger systems, or where you need lots of flexibility. It allows you to have multiple camera inputs and switch any camera to a monitor, usually there are more than one monitor outputs, so you can view more than one cam (on different monitors). Some include telemetry, so whatever cam is selected can be controlled by the keyboard (panned / tilted / zoomed, and also operation of wash/wipes/lamps etc). Other features can include alarms etc. Usually you would split up a very large system into smaller blocks, say 16 cams going into a matrix, with a couple of monitor outputs (say a main one and a spot one) controlled by one keyboard/joystick. It saves having a keyboard for every camera, and means you can route pretty much any cam to any output you require. They will be designed (or should be!) for expandability, so you can grow the system as and when required, and usually cost a pretty penny, but are robust and should last a long time.
