What is PTZ Camera?

PTZ Dome Security Camera
PTZ stands for Pan, Tilt, and Zoom. A PTZ dome security cameras differ from a fixed dome camera in that it can move left and right (pan) or up and down (tilt). These security cameras can also zoom in and out, making it very feature-rich. These domes require a keyboard and a receiver to operate PTZ functions. Most PTZ dome security cameras have receivers built in to them, however. Using the keyboard, PTZ domes can be programmed to view an area and/or can utilize alarm triggers to induce movement by the camera. A series of motions can be programmed by the user for the security cameras to follow. For example, PTZ security cameras can be programmed to sweep a parking lot every 10 minutes. Additionally, triggers such as motion detection or door contacts can alert the camera to reposition itself.

The total zoom capability of PTZ security cameras is actually a combination of digital zoom and optical zoom. Digital zoom uses electronics to zoom in and out while optical zoom uses lens motion. The total zoom of a camera can be calculated by multiplying the digital zoom by the optical zoom
