What type of camera can be remotely controlled to change its field-of-view?

• A. Pan-Tilt-Zoom (PTZ) camera
• B. Fixed camera
• C. Dome camera
• D. Infrared camera

Answer: (A)

The ability to remotely change what you see hinges on having motors that move the camera’s orientation and its magnification. A Pan-Tilt-Zoom camera is built to do exactly that: it can pan (rotate horizontally), tilt (move vertically), and zoom (adjust magnification) from a remote operator or software. This combination lets you sweep wide areas, focus on a specific detail, or track a moving subject without physically touching the camera. Fixed cameras do not move or zoom, so their field of view is constant. Dome cameras describe the housing style and can be fixed or PTZ, but the key feature that enables changing the view remotely is the pan-tilt-zoom capability. Infrared cameras refer to imaging in the infrared spectrum and don’t imply any particular control over the field of view.
