Which of the following best describes "covert cameras"?

Covert cameras are specifically designed to be hidden from view, allowing them to capture video surveillance without drawing attention. This discretion is crucial in various applications, such as security, monitoring, and investigative work, where observing behavior without the subjects' knowledge is important. The stealthy nature of covert cameras enables them to operate unnoticed, making them effective in capturing candid footage and ensuring surveillance remains unobtrusive.

In contrast, high-quality cameras for live events focus on delivering clear imagery and are typically set up in visible locations to cover a particular scene, making them not suited for covert purposes. Similarly, cameras that are easily visible to the public are the exact opposite of what covert cameras represent, as their visibility would diminish their effectiveness. Lastly, while cameras used primarily in homes may include a variety of designs, not all are covert, as many can be easily seen and recognized as security devices. Thus, the defining characteristic of covert cameras is their ability to remain hidden from those being observed.
