How high of a frame rate would a high security camera typically require?
A. It depends on several factors. Direction of motion within the view of the camera is one. If the subject is moving toward the camera (vertically within in the frame), less frames per second (fps) is needed if the motion is from left to right within the frame. The velocity of the motion is also important, and that is also relative to how close the object is to the camera. Some rules of thumb are 2 to 3 fps for parking lots with wide field of view, 5 fps for school hallways, 12 to 15 fps at cash registers. Typically, full motion video is not required for surveillance applications. Movies are 24 fps as a point of reference. The Cisco 4000 series supports 6 fps at 1280 x 720 (720p) and 30 fps at 1920 x 1080 (1080p) resolution.
