What is a PTZ camera and how does it work?
A PTZ (Pan-Tilt-Zoom) camera is a type of surveillance camera that can be controlled remotely to pan, tilt, and zoom in on specific areas of interest. This allows users to capture high-quality images and videos of specific objects or individuals, even from a distance. PTZ cameras are commonly used in security and surveillance applications, such as monitoring public spaces, borders, and critical infrastructure.
PTZ cameras typically consist of a camera unit, a control unit, and a communication link. The camera unit is equipped with a motorized pan-tilt head that allows it to move horizontally and vertically, while the control unit sends commands to the camera unit to adjust its position and zoom level. The communication link can be wired or wireless, depending on the specific application and requirements.
