A surveillance camera and illuminator are covertly mounted in a partially rotatable bay window inner frame mounted within an electrical switch box. The bay window inner frame can thus be pivoted back and forth to orient the camera toward an entrance to a room in which the switch box is mounted. When the bay window inner frame is rotated to the desired position, a bay window switch box decor cover plate is mounted over the bay window inner frame, engaging it and locking it in the selected position by attachment of the cover plate to the switch box.
