PTZ is an abbreviation for pan, tilt, and zoom and reflects the movement options of the camera, and a pan–tilt–zoom camera (PTZ camera) is a camera that is capable of remote directional and zoom control. A PTZ camera is not a still camera. Instead, it could move the camera and the lens, and that means a single camera can be used to monitor places that should be covered by multiple ones. You can save a lot of cost and time in purchasing and deploying the camera if a PTZ camera can handle the job. With its moveable lens, you will also be able to zoom the camera to see a specific area that you are interested in. To conclude, it’s “do more with less.”
