The frequency at which images are captured and stored by cameras depends largely on the type of camera being used. Digital cameras typically take pictures in rapid succession, storing each image as a file on an internal memory card or other storage device. Some digital cameras have burst shooting modes that enable them to capture multiple frames per second until the shutter button is released. Security cameras often take photographs at set intervals or when motion is detected within its field of view, while professional-grade equipment may be able to record hundreds of frames per second for high-speed analysis and slow motion playback.
