Motorized mechanisms in a PTZ (Pan-Tilt-Zoom) camera allow for zooming in and out through the use of a motor-driven lens system.
The zoom function in a PTZ camera is typically achieved through the movement of lens elements within the camera lens. These lens elements are controlled by motors which are able to adjust the focal length of the lens, thereby changing the magnification of the image being captured.
When the user commands the camera to zoom in, the motorized mechanism within the camera adjusts the lens elements to decrease the focal length, allowing the camera to capture a closer view of the subject. Conversely, when the user commands the camera to zoom out, the motors adjust the lens elements to increase the focal length, providing a wider view of the scene.
Overall, motorized mechanisms in a PTZ camera enable precise control over the zoom function, allowing users to capture detailed close-up shots or wide-angle views with ease.
