What is the function of a pan-tilt-zoom (PTZ) camera?

A pan-tilt-zoom (PTZ) camera is designed for remote control of the camera's movements, which includes the ability to pan (move horizontally), tilt (move vertically), and zoom in or out to focus on particular details within a scene. This functionality allows operators to monitor large areas more effectively compared to stationary cameras, as they can adjust the camera's position and focal length to respond to changing conditions or specific incidents.

The capability to control the movement remotely is particularly valuable in surveillance scenarios where situational awareness is crucial. Operators can track moving subjects, zoom in on points of interest, and cover wider areas without the need for multiple fixed cameras. This versatility makes PTZ cameras a popular choice in both security and monitoring applications, providing a dynamic viewing experience that enhances overall surveillance effectiveness.
