6. Loosen the pan and tilt adjustment screw on the bracket to turn the housing into the
desired position. Then tighten the screw (fig. 13).

Attention:
Please make sure that the lens used for the camera in the housing does
not have a convex mirror object lens. Otherwise, a „concentric circle“ will appear on
the image when the IR-LEDs are activated (fig. 16).
