What is a common use for PTZ (Pan-Tilt-Zoom) cameras in CCTV systems?

PTZ (Pan-Tilt-Zoom) cameras are designed to provide flexible surveillance capabilities, allowing a single camera to cover a larger area by adjusting its position and zooming in on specific subjects or incidents as needed. This versatility is a key advantage of PTZ cameras, as they can rotate horizontally and vertically, as well as zoom in and out, making them particularly effective for monitoring expansive environments such as parking lots, large retail spaces, or public areas.

Utilizing a PTZ camera means that operators can manage coverage dynamically, focusing on areas that require attention without the need for multiple fixed cameras covering the same space. This capability not only enhances surveillance effectiveness but also simplifies the infrastructure required for monitoring large areas, thereby making it a common choice in CCTV systems. The other options, while potentially valued in different contexts, do not accurately reflect the primary function of PTZ cameras.
