Pan-tilt-zoom (PTZ) refers to a type of camera that can move horizontally (pan), vertically (tilt), and zoom in or out. This functionality allows the camera to cover a wide area and focus on specific details, making it ideal for surveillance, broadcasting, and video conferencing. PTZ cameras are often used in security systems to monitor large spaces, such as parking lots or public events. They can be controlled remotely, enabling operators to adjust the camera's position and zoom level in real-time, enhancing their ability to capture important footage or observe activities from a distance.
