ABSTRACT:
A surveillance system wherein a TV camera is pivotally mounted along its optical axis on or along a ceiling, and a mirror is pivotally mounted about an axis perpendicular to the optical axis to intercept the view of the camera. Then, by selected rotation of the camera and mirror about these axes, both pan and tilt functions are achieved in a very compact structure.
