A convenience store needs a camera to cover the entrance. Identification is needed at 80 pixels per face. Given that the scene is 2 m (6 ft 7 in) wide, which of these resolutions is the minimum one needed?
To achieve identification at 80 pixels per face for a scene that is 2 meters (6 feet 7 inches) wide, a minimum resolution of 1280 x 720 is needed. This calculation ensures that each face captured in the frame meets the pixel density requirement for clear identification purposes.
