Abstract
An improvement in a photoelectric intrusion detector unit of the type designed to resemble a duplex electrical outlet. An angled mirror and a collimating lens are supported on a common mount which is rotatable about an axis of rotation which is angularly displaced from the optical axis of the lens but passes through its focal point. The optical axis of the lens describes a conical surface about the axis of rotation.
