SECTION 1
KC-2A CCD COLOR OBSERVATION CAMERA
1.1 PURPOSE
The KC-2A CCD color observation camera provides a low cost
solution to closed circuit television and security surveillance
applications. The KC-2A camera features:
•1/3” interline transfer CCD image sensor
•Supports standard CS- or C-mount lens
•Equipped with electronic iris
•Compatibility with video auto-iris lens
•Excellent picture quality
•Two-year warranty
This manual describes how to setup and operate the KC-2A
Camera.
1.2 SYSTEM INSTALLATION
Installation of the KC-2A camera must be performed by qualified
service personnel in accordance with all local and national
electrical and mechanical codes. Perform the following steps to
install the KC-2A camera.
A. Remove all components from the package and identify the
items that will be used during installation:
•KC-2A camera
•KO-500 camera stand
•KO-60 camera cable
Other items used during the installation that are NOT
supplied with the KC-2A camera may include:
•Camera lens
•Mounting hardware
•Observation monitor
Refer to Figure 1 for identification of the KC-2A camera.

B. Select a suitable location for the camera. Install the camera
stand or mounting bracket in the selected location using a
suitable fastener. The camera stand or mounting bracket
must be attached to a structural object, such as a wall stud
or ceiling rafter, that will support the weight of the camera
and mount.
C. The KC-2A camera has a threaded mounting hole on the
bottom and top of the camera housing to allow for bottom or
top mounting. The ¼"-20 UNC threaded mounting hole
attaches to the bolt on the camera stand or mounting
bracket.
NOTE: Do not aim or point the camera towards the sun or
into a strong light.
D. Attach a CS-mount lens directly to the front of the camera
lens mount. If a C-mount lens is used, the CS/C back focus
ring must be adjusted to the “C” setting.
E. If an auto-iris lens is used, connect the cable to the terminal
block for a video-type auto-iris lens.
F. Route the assembled cable from the monitor to the camera.
G. Plug the cable into the connector port labeled “MONITOR” on
the rear of the camera.
H. Plug the other end of the cable into the corresponding
camera connector port on the rear of the monitor.
I. Adjust the lens focus and iris controls for an optimum picture.
1.3 WHITE BALANCE ADJUSTMENT
This adjustment is used to place the white balance function of the
camera into the AUTO (Automatic) or MANU (Manual) mode. If
the switch is placed in the AUTO position, the camera will
automatically try to maintain white objects as white even if the
light color changes. If the switch is placed in the MANU position,
the user can adjust the R (Red) and B (Blue) controls until white
objects are seen as white on the monitor. The MANU position is
primarily used when viewing objects under colored lights.

1.4 MANUAL IRIS LENS ADJUSTMENT
When using the manual Iris lens, turn the iris to the OPEN
position and adjust the manual iris for the appropriate range.
Adjust during the brightest conditions, opening the lens without
saturating the picture. Set the EI switch to ON. Adjust the lens
opening for the minimum F-number yielding a good picture under
the brightest scene conditions.
The manual iris is used in indoor applications where lighting from
windows can considerably affect the light level of the room.
1.5 VIDEO-TYPE AUTO IRIS LENS INSTALLATION AND
ADJUSTMENT
The KC-2A camera supports video-type auto iris lenses to adjust
for changing light levels. Perform the following steps to install and
adjust a Video-type auto iris lens.
A. Thread the video-type auto iris lens on to the lens mount.
B. Connect the lens control wiring to the three-position terminal
block on the back of the camera. The following diagram
illustrates the Pin connections. Red, white, and black are the
most common colors used for wiring on video-type auto iris
lens.
A. Pin A. Name A. Wire Color
B. +B B. Voltage + B. Red
C. VI C. Video C. White
D. G D. Ground D. Black
C. Set the EI switch on the back of the camera to OFF.
D. Apply power to the camera.
E. Adjust the focus ring on the lens for an optimum picture. If a
picture is not visible, set the lens for proper exposure by
adjusting the ALC (automatic level control) and Level on the
lens. The ALC setting can range between AVG (average) or
PK (peak). A mid-range setting is appropriate for most
applications.
F. For ALC adjustments:

5
AVG To slow the reaction of the lens to changing light,
set the range to the AVG setting to average the
video level from the camera. Use when there are
bright spots in the picture such as lights or glare
from the sun.
PK To increase the speed of the lens reaction to the
changing light, set the lens adjustment to PK so
the lens will adjust to the brightest or peak object
in the video. Use this setting if you want to see
the brightest object and not the background
objects.
G. For Level adjustments:
1. Adjust the level control for the best picture during the
day. A night adjustment may not provide the proper
setting for controlling the light during the day.
2. Set the back focus of the camera before the final
adjustment of the video level.
H. If the auto iris has a gain adjustment:
1. If the lens oscillates between open and closed under
bright lights, slowly turn the gain adjustment counter
clockwise until the oscillating stops.
2. Increase the light getting to the camera by adjusting the
level control and re-adjusting the gain control as
necessary.
3. Reset the level control as noted in step E.
1.6 BACK FOCUS ADJUSTMENT
For best results, perform back focus adjustments at night or
while using a #6 or #8 welder’s glass in front of the lens. The
focus of the camera will change slightly if the camera iris was
adjusted on a light scene, then changes to a dark scene.
However, the camera will remain in focus if the iris was focused
on a dark scene and the scene lightens.
A. The lens should be mounted on the camera, then apply
power.

6
B. If a picture is visible, focus on the picture. If the picture is not
visible, open the iris on the lens. Open the lens as wide as
possible by adjusting the iris ring on the lens for the brightest
picture or by placing the welder’s glass in front of the lens
and forcing the lens to automatically open.
C. When the iris is open to the widest point, re-adjust the focus
for a clear picture. It a clear picture is not possible, set the
focus ring to midrange.
D. Loosen the back focus lock screw.
E. Adjust the back focus ring for a clear picture.
F. Tighten the back focus lock screw.
G. Fine tune the focus with the focus ring on the lens.
H. Remove the welder’s glass from in front of the lens.
I. Adjust the iris of the lens for the best picture quality.
1.7 ZOOM LENS BACK FOCUS ADJUSTMENT
The objective of back focusing a zoom lens is similar to that of a
fixed focal length camera, except that the back focus is also
adjusted to maintain the focus when “zooming” the lens in and
out on a scene.
A. Choose an object at the farthest range that you wish to look
at with a zoom lens.
B. Make sure the iris of the lens is wide open. (Do this by
adjusting the camera at night or use a welder’s glass in front
of the lens.)
C. Adjust the focus to the stop on the far range.
D. Adjust the zoom on the lens to obtain the widest picture.
E. Loosen the back focus lock screw.
F. Adjust the back focus ring for the clearest picture.
G. Tighten the back focus lock screw.
H. Adjust the zoom on the lens to the far telephoto position.

7
I. Adjust the back focus ring for the clearest picture.
J. Adjust the zoom on the lens back to the widest picture.
K. Loosen the back focus screw.
L. Readjust the back focus for the clearest picture.
M. Tighten the back focus lock screw.
N. Repeat the previous steps, as many times as necessary, to
maintain a clear picture through the entire zoom range.

TROUBLESHOOTING AND MAINTENANCE
2.1 TROUBLESHOOTING
If problems occur, verify the installation of the camera with the
instructions in this manual and with other operating equipment.
Isolate the problem to the specific piece of equipment in the
system and refer to the equipment manual for further information.
Problem Possible Solution
No Video 1. Verify power to all pieces of equipment
in the system.
2. Verify that the power switches are in
the ON position.
3. Verify that the lens cap has been
removed from the lens or that the iris
of the lens is open.
Video, but no control 1. Power down the system for one
minute, then turn power back ON.
2.2 PREVENTIVE MAINTENANCE
Preventive maintenance allows detection and correction of minor
faults before they become serious and cause equipment failure.
Every three months, perform the following maintenance:
a) Inspect all connecting cables for deterioration or other
damage.
b) Clean components with a clean damp cloth.
c) Verify that all the mounting hardware is secure.
