Pan Tilt Zoom Cameras
PTZ Cameras are cameras that can be moved via a computer, DVR, or PTZ joystick. PTZ stands for Pan, Tilt, and Zoom. These cameras can be controlled to move left to right, up and down, and zoom in and out. All of this is done through the controller. These types of cameras are often found at gas stations and large retail stores. Typically the dome-type cameras you see either hanging from the ceiling or attached to the ceiling at a store is a PTZ camera. They can easily be used to follow an event or person as they move about. One distinct advantage PTZ cameras have is the ability to zoom. You can zoom in on someone's face, a license plate, a cash register, or virtually anything else.
