Which feature can enhance a PTZ camera's autofocus capabilities?

The feature that significantly enhances a PTZ camera's autofocus capabilities is laser focus. Laser focusing technology uses a laser beam to measure the distance to the subject, allowing for quick and precise focusing. This is particularly beneficial in environments where lighting conditions are variable or when tracking fast-moving subjects, as it provides a more accurate distance measurement compared to traditional autofocus methods that rely solely on contrast detection.

In contrast, while wide dynamic range, optical zoom, and low-light sensitivity are important features, they do not directly improve the autofocus mechanism. Wide dynamic range helps the camera handle scenes with both bright and dark areas, optical zoom allows users to zoom in on distant subjects without losing image quality, and low-light sensitivity enhances the camera's ability to capture images in poor lighting conditions. However, none of these features contribute to the autofocus speed and precision like laser focus does.
