Glossary

Some cameras are fixed while others can move around. Those that can move around are called “PTZ cameras”, or “Pan-Tilt-Zoom Cameras”, as they can pan and tilt (move up and down and to the sides) and they can zoom in and out – mechanically. PTZ cameras usually rely on motors to move, in which case they make a bit of noise, or they can use magnetic mechanism, which is way too cool to be cheap enough to use.

PTZ cameras are the standard for room-system video conferencing endpoints, where people would like to control where the camera is pointed.

Usually, you can control a PTZ camera remotely when you are engaged in a video conference. This is acheived by using FECC (Far End Camera Control) technology.
