Which of the following statements is true about PTZ controls?

PTZ controls are designed specifically to allow for remote control of camera functions such as direction (pan and tilt) and zoom capabilities. This functionality is essential for monitoring large areas or tracking moving objects effectively, as it enables an operator to adjust the camera’s position and focal length remotely without needing to physically access the camera.

The other options present various attributes that do not accurately represent PTZ controls. For instance, adjusting lighting levels pertains more to light management systems rather than camera control, while the idea that PTZ controls are only for wireless cameras is misleading since they can be used with both wired and wireless setups. Lastly, stating that PTZ controls require no electrical power is incorrect, as these systems depend on electrical power to function properly, including motors for movement and zooming. Overall, the ability to manipulate direction and zoom remotely is the defining characteristic of PTZ controls, making that statement the true assertion.
