A camera that uses a ball-and-socket design is a _____.

A camera that uses a ball-and-socket design is known as a turret camera. The turret design allows for flexible positioning and easy adjustments in the camera's orientation. This design enables users to tilt the camera up and down as well as pan left or right, while maintaining a more streamlined and aesthetic appearance compared to other camera types.

In contrast, dome cameras typically have a dome-shaped protective casing and may not offer the same range of motion. Box cameras are fixed in position and primarily used in applications where specific angles need to be monitored without the need for adjustment. PTZ (Pan-Tilt-Zoom) cameras, while they do feature movement capabilities, are distinct in that they allow for control over both pan and tilt functions, as well as zoom capabilities, from a remote location. The bullet point of focus here is the specific mention of "ball-and-socket design," which is characteristic of turret cameras, allowing for their unique versatility in positioning.
