What is the significance of a camera's field of view (FOV)?

The significance of a camera's field of view (FOV) lies in its role in determining the extent of the area visible through the camera's lens. FOV is a crucial aspect of camera design that impacts how much of the scene gets captured. A wider FOV allows a camera to cover more area, which is particularly beneficial in surveillance and monitoring applications where observing broader environments is important.

Understanding FOV helps in selecting the right camera for specific installations. For instance, a camera with a narrow FOV may be suitable for a focused shot, such as capturing a person's face at a close range, while a wider FOV camera is ideal for monitoring larger spaces, like parking lots or open areas. This versatility in coverage enables users to minimize the number of cameras needed while ensuring key areas are monitored effectively.

Other factors mentioned, like resolution, distance of wireless transmission, and recording speed, do not directly relate to FOV. Instead, they pertain to different technical specifications and capabilities of the camera system. Hence, recognizing the FOV’s importance is essential for effective surveillance system design and application.
