A measure of effectiveness of a camera's deployment includes the camera's effectiveness in providing image information to computer-vision applications. In addition to, or in lieu of, measures based on the visual coverage provided by the deployment of multiple cameras, the effectiveness of the deployment includes measures based on the ability of one or more computer-vision applications to perform their intended functions using the image information provided by the deployed cameras. Of particular note, the deployment of the cameras includes consideration of the perspective information that is provided by the deployment.
