What is a key characteristic of the Box Camera?

The key characteristic of a Box Camera is the presence of a changeable lens. This feature allows for greater flexibility and adaptability, enabling users to select different lenses based on the specific requirements of their application. By using interchangeable lenses, operators can optimize the camera's performance for various scenarios, such as different focal lengths or field of views, which enhances the overall functionality and versatility of the camera system.

In many setups, having the option to change lenses can significantly improve image quality and capture ability according to the shooting environment, leading to better surveillance outcomes. The ability to customize the optical components according to specific needs is a significant advantage for professionals who require more than what a fixed-lens camera provides.
