INFORMATION
This equipment generates and uses radio frequency energy and if not installed
and used properly, that is, in strict accordance with the manufacture’s
instructions, may cause interference to radio and television reception. If does
so, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
･Reorient the receiving antenna;
･Relocate this equipment with respect to the receiver;
･Move this equipment away from the receiver;
CAUTION
To prevent electric shock, do not use the polarized plug of the AC
Power adapter with an extension cord, receptacle or other outle
t
unless the blades can be fully inserted to prevent blade exposure.
When the camera is used within an electromagnetic field, beat
interference(vertical, horizontal or diagonal stripes) may be
created in the video output. If this occurs, take measures on the
source of the electromagnetic waves to prevent the emissions
from affecting the video output.
Such measures are particularly necessary on systems with servo
motors, inverters and other equipment that tends to generate
electromagnetic waves.
Do not subject the camera to strong shocks, as this may result in
failure or breakage.
When the camera is used on system which subject the camera
connector to strong shocks, the camera connector may suffer
damage. If the camera is used on such systems, the connector
plug should be fastened to the camera with the optional camera
connector bracket.
WARNING
TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE
THIS APPLIANCE TO RAIN OR MOISTURE.
This equipment should be used with DC12V only.
Do not use any other power source.

２
･Plug this equipment into a different outlet so that this equipment
and receiver are on different branch circuits.
If necessary, the user should consult the dealer or an experienced
radio/television technician for additional suggestions.
Thank you for purchasing the TELI
CS8420Ci TV B/W camera featuring
compact and lightweight.
To take best advantage and gain the most service from your camera, read this
operation manual carefully and thoroughly.
1.FEATURES
* Compact and light weight
* Available External sync-operation
* Equipped with an electronic shutter for fast moving subjects for better
definition picture.
2.PRECAUTION
(1) This equipment should be used with DC12V only. To prevent electric
shocks and fire hazards, do not use any other power source.
(2) The CS8420Ci is designed to be used with CCIR monochrome television
signals. It cannot be used for playback with a television of a different
standard.
(3) Please handle the equipments carefully.
(4) Do not point your camera lens directly into sunlight or strong artificial
light. This might cause irreparable damage to the image sensor.
Also, be sure to use the lens cap when the camera is not in use.
(5) Do not expose the camera unit to high temperatures. For example, do not
place it near a stove for long periods, or in direct sunshine or in a car in
hot weather. Heat may cause some malfunction.
(6) Keep the camera clean. Dust can damage the camera and cause trouble in
moving parts.Take particular care to avoid the entry of sand or grit when
changing the camera lens.
(7) This camera is not protected with an anti-dust glass cover. Make sure to
put a lens or lens cap to protect the image pickup plane from dust and/or
scratch even when the camera is not in use. Before mounting a lens to the
camera, remove dust from the CCD image plane. Don't use any organic
solvent other than ethyl alcohol to remove dust or stain from the CCD
plane. To avoid condensation trouble, when you need to move the camera
from/into cold/hot room, it's advisable that you leave the camera lying
around at a new location for a while before starting to use it.
(8) Avoid jolting the equipments or exposing it to vibration.
(9) Never attempt to dismantle the equipments.
３
(10) Avoid folding or stretching the camera cable or other connection cable
between equipments.
(11) When the cabinet is dusty, clean by gently wiping with soft cloth. And
avoid the use of strong cleaning agents such as benzine or alcohol as they
maydamagethecabinet.

10 for GND.
(2) Video output
Composite CCIR video output (VS) is output from 4 (HOT) and 3 (GND).
(3) Input pulses for external sync
When required external sync-operation between other equipments, use it
her one of pulses for HD/VD, VS or SYNC. And input HD pulse from pin
number6-5 (GND) and VD from pin 7-12 (GND) for HD/VD external sync
operation. And input VS or SYNC from pin 7 and 12 (GND) for external sync
operation by VS or SYNC.
CAUTION
There are two video output which are from VIDEO OUT (BNC)
and DC IN/SYNC pin 4-3 (GND).
Do not use both of them same time, because it may occur double
termination with the video output, and the video output will be
half.

5.Operation
(1) After the connection equipments, turn the power switch for the video
monitor on at the first.
(2) Turn the power switch for the camera to ON, and make sure the image
appears on the monitor screen.
(3) Adjust the lens aperture for the proper image brightness.
(4) Adjust the focus ring on the lens for the sharpest picture looking at the
monitor.
6.SUPPLMENTALINFORMATIONS
(1) Illuminance for better picture
“illuminance” (also called “luminance”) is intensity or brightness of light,
expressed in lx or foot-candles (fc).
The CS8420Ci is designed to provide best pictures under the condition, of
a 1500 lx (130 fc) illuminance.
To obtain good pictures under very bright object, the use of an ND (neutral
density) filter is recommended.
IMPORTANT
To ensure maximum performance, be sure to keep the inside of
lens and inner part of camera module free from dust or
fingerprint.
CAUTION
If the lens (C-mount) size exceeds 100mm in diameter, 170mm in
length and 1000g in weight, both the camera and lens should be
secured.
Because the camera housing-strength is not enough to support
such a weight or stress, may cause damage it.
CAUTION
Don’t equip a lens to incline. And please use lens which have n
o
flaw and dust at mount hole, or the lens maybe don’t remove.

10.HOWTOFIXCAMERA
(1) Use tripod
If you use tripod, use camera mounting kit (optional) and fix camera.
(2) Use fixing holes on camera flange
When mounting your camera by using camera-mounting holes located at
the camera flange, (total 2 places), make sure to use M3 screws. Use
screws which don’t go inside the chassis deeper than 4mm, measured from
the bottom side. Any longer screws may damage the inner circuit board.

１４
(3) Use fixing holes on the bottom of camera
When mounting your camera by using camera-mounting holes located at
the bottom chassis, (total 4 places), make sure to use M3 screws. Use screws
which don’t go inside the chassis deeper than 3mm, measured from the
bottom side. Any longer screws may damage the inner circuit board.
* If you fix camera, we recommend to use both item (2) and (3).
11.APPEARANCES
CAUTION
If the screw is long, it touches with printed circuit board, and it
causes some trouble and accident.
