The Pan Tilt Zoom dome surveillance camera or PTZ dome surveillance camera 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 model can do just that–Pan, Tilt, and Zoom.
What is Pan-Tilt-Zoom or PTZ? Panning is the ability of the camera to move about a horizontal plane; in other words the camera can turn from left to right and/or all the way around in a circle. Tilting refers to the cameras ability to move about a vertical plane, in other words the camera can move 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.
