The Pan Tilt Zoom camera or PTZ is one of the most versatile dome cameras on the market today. Not only does it offer the standard electronic features of most other dome cameras, but the PTZ can do just that–Pan, Tilt, and Zoom.
In the video industry, Panning is the ability of the camera to about a horizontal plane, simply put turning from left to right and all the way around in a circle. Tilting refers to the cameras ability to move about a vertical axis, once again simply put up and down. With no walls, poles, or mounts to impede the view, a pan tilt zoom camera can easily maneuver its lens in any position equal or greater to that of an area covering 1/2 sphere.
