CA 2639527

A security camera system according to present invention embodiments includes a telephoto type lens with one or more factors of optical zoom. A set of prisms that steer incoming beams from the surrounding environment (to adjust the field of view) is disposed in front, of the lens. The security camera system preferably includes a wide angle staring mode that encompasses a large field of view, where the prisms are oriented to provide no steering effect. The security camera system further includes a high-resolution zoom mode, where the telephoto lens focuses on a region of interest and the prisms perform beam steering to adjust the field of view and enable the region of interest or an object to remain at the center of the security camera system view. Image processing techniques may be employed that consider the beam steering angle and the field of view to compensate for distortion effects.
