Abstract
A method and apparatus for detecting motion in a large area with a single imaging device, such as a camera. A fixed object is located in the area and a camera is panned across the area with the fixed object remaining in the field of view of the camera. Successive images are adjusted based on the position of the fixed object within the image and the adjusted images are compared to detect movement with an area of overlap between the images.
