3.9. Camera Mounting And Connections – Standard Lens.
Fit the camera mounting bracket onto the door arm as shown in fig 5c and 5d. Note that the
camera shown in fig 5c and 5d is not fitted for this operation.
Mount the standard lens and camera assembly (fig 5b) onto the camera mounting bracket as
shown in fig 5e and 5f. Rotate the lens and camera assembly anti-clockwise to locate in position.
The socket head screws are fixed in position and do not require tightening. Ensure that the
camera is in a horizontal position. To rotate the camera independently of the lens hold the lens
firmly in position, push the camera towards the lens and rotate it in the desired direction.
The camera power cable is secured to the rear of the camera by a security bracket. Do not
remove this bracket. Connect the camera power cable to the 12V DC camera supply socket on
the front of the door arm. See fig 11.
Connect the camera video cable from the front of the door arm to the ‘video out’ socket on the
back of the camera.
3.9.1. Camera and lens settings.
The camera and lens are pre-adjusted to give the best quality picture. The following settings have
been made.

The shutter switch on the rear of the camera must be set to OFF when using the standard
auto-iris lens.

The standard auto-iris lens has two adjustment screws on the lens body. The screw marked
ALC is set to A (fully clockwise). The screw marked LEVEL is set to L (fully
anticlockwise).
3.10. Camera Mounting & Connections – Zoom Lens.
The zoom lens is supplied as an option. It shares the camera and lens heat shield assembly used
with the standard lens. See fig 5g showing the zoom lens assembly and lens clamp.
3.10.1. Assembly of the zoom lens.
Disconnect the auto-iris plug from the camera and unscrew the camera from the standard lens. It
is not necessary to remove the 5mm spacer ring from the rear of the standard lens (see fig 5b).
Screw the camera onto the rear of the zoom lens assembly (see fig 5h).
Unscrew the lens heat shield assembly from the front of the standard lens. It is not necessary to
remove the 43-49mm step up ring from the front of the standard lens (see fig 5b).
Screw the lens heat shield assembly onto the front of the zoom lens assembly (see fig 5j).
3.10.2. Zoom lens mounting.
Note: The zoom lens and camera assembly must be removed from the door arm before opening
the door. The door slide mechanism is not designed to carry the extra weight of the zoom lens
assembly when the door arm is fully extended. The swing bolts which secure the door cannot be
swung clear of the door when the zoom lens mounting bracket is in position; only mount the
zoom lens bracket when the door is closed and the swing bolts are secured.
The zoom lens and camera assembly can be conveniently stored between tests by standing it on
its end as shown in fig 5p.
Secure the zoom lens and camera assembly to the zoom lens mounting bracket using the screw
fixing in the top of the ball joint. Remove the standard camera mounting bracket from the door
arm; see fig 5c and 5d. Mount the zoom lens and bracket onto the door assembly by sliding the
bracket onto the three fixing screws on the front of the door assembly; see fig 5k. The socket
head screws are fixed in position and do not require tightening.
