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 useful for surveillance, broadcasting, and videoconferencing. PTZ cameras can be controlled remotely, enabling operators to adjust the view as needed. These cameras are commonly used in various settings, including security systems, live event coverage, and traffic monitoring. Their versatility and ability to capture dynamic scenes make them a popular choice for both professional and personal use.
