Pan, tilt, and zoom cameras are some of the most versatile cameras on the market. They can pan (move left and right), tilt (move up and down), and zoom in or out. Additionally, PTZ domes can rotate 360 degrees and view an object directly below them.
A camera∆s motion is remotely controlled with a keyboard. Patrol movements can also often be programmed. These allows users to pan, tilt, and zoom into a specific area with just a push of a button. Preset patterns can also be triggered automatically even when the user is not near the keyboard. This is done by connecting devices such as magnetic door contacts, motion detectors, and panic buttons directly to the camera. When a certain device is triggered, the camera can move to look in a predetermined specific location.
