PTZ cameras use lasers to measure the distance to the target, which allows for quick and accurate focusing. The laser range finder determines the precise distance between the camera and the subject, enabling the camera to adjust its focus optimally. This technology ensures that the camera can focus rapidly and accurately, even in challenging lighting conditions or when the target is moving. Axis Communications' technical specifications for PTZ cameras confirm that laser technology is employed to enhance focus performance by providing target distance information.
