1. Handle the camera with care.
Be careful when handling the camera, do not drop it or subject
it to strong shock or vibration to prevent any damages to it. Do
not disassemble it or place it on an unstable base.
2. Do not install the camera near electric or magnetic fields.
Installed the camera away from TV, radio transmitter, magnet,
electric motor, transformer, audio speakers because the
magnetic fields generate from above devices will distort the
video image.
3.Do not install the camera in the high temperature environment.
Installed the camera away from stoves, or other heat generating
devices as the high temperature could cause deformation,
discoloration or other damages of the camera.
Install the camera at where the temperature range will stay
between -35℃~ +50℃for DC12V, -45℃~+50℃for AC24V
.
4. Never face the camera toward the sun.
Never aim the camera at the sun or other extremely bright objects
whether it is in use or not.
5.Cleaning
Do not touch the surface of CCD sensor by hand directly. Use a soft
cloth to remove the dirt from the camera body. Use lens tissue or a
cotton tipped applicator and ethanol to clean the CCD sensor and the
camera lens. When the camera is not in use, put the cover cap on the
lens mount.

1. Using the supplied screws, mount the bracket base on the desired
location.
2. Connect the BNC connector of the camera to a monitor or other video
device through a 75 ohm type coaxial cable with BNC female connector
at cable extension.
3. Connect the AC24V or DC12V regulated power source of the camera
(power jack) to the power-in jack with 2mm plug. For DC12V power
source, please make sure the power plug is center+ outer-for heater
normal operation.
4. Our factory settings is for you to get the best image within about 3~5
meters (for veri-focal lens f=3.5~8mm) or 5~10 meters (for veri-focal
lens f=9~22mm) . If it is out of focus, or any other adjustment is required,
follow the procedures below.
a. Remove the fixing screw in the front,which hold the sun shield
cover. Remove the sun shield cover.
b. Twist open and carefully remove the housing cover.
(Please pay attention to prevent damage to the “O”-Ring seal.)
c. Loosen the focal lens and focus locking screws.
d. Adjust the lens to bring the subject into focus.
(Caution: Heater elements could be hot! When camera power is on,
use caution when adjusting the camera.)
e. Retighten the screws.
f. Please refer to the Settings section for the details of the other

g. When all the adjustments and settings are completed, overlaying the
cover gently. Be careful not to damage to the “O”-Ring and camera
components.
h. To reassemble the sun shield, match the hole on the sun shield to
the back fixing plate of camera, Fix the screw on the front fixing plate.
Make sure the wider side of the fixing plate holdsthe edge of the
camera well.
5. Attach the camera onto the mounting bracket.
6. Loosen the swivel screw and point the camera to the desired direction.
7. Tighten the swivel screw. To strengthen the fixing power of the swivel
screw, tighten the set-screw with the set-screw wrench. (supplied)
Notes:
(A) Make wiring connections only after it has been determined that
power has been disconnected.
(A) There is a desiccant pack attached to the housing base under the
camera which is designed to absorb any moisture trapped inside the
housing during adjustment. To avoid excessive moisture build up,
it is recommended that the camera not be installed in rainy or
excessively damp conditions. It is also advisable to limit the
number of times the housing cover is removed. The desiccant pack
can be replaced if condensation develops inside the housing.

Control Switches

??The 4 control switches are also located on the side circuit board, the
switches in orders are for Flickerless, Back Light Comp, Auto Gain
Control and Line Lock.
FL(Flickerless)Normal/On
When picture flicker fiercely, turn FL on, then the camera will stabilize the
speed of electronic shutter at 1/100(NTSC) or 1/120(PAL) automatically,
and reduce the flicker immediately. The default setting is Normal.
BLC (Back Light Compensation)Normal/On
When BLC is turned on, the AGC, ES and IRIS operating point is
determined by averaging over the center area instead of entire field-of-view,
so that a dimly-lit foreground object at center area can be clearly
distinguished from brightly-lit backgrounds.
BLC should not be used unless it is needed to compensate for back-lit. The
default setting is Normal.

AGC (Automatic Gain Control)Off/On
AGC ON: The sensitivity increases automatically when light is low.
AGC OFF: A-low-noise picture is obtained under a low light condition.
The default setting is On.
LL (Line-Lock)Off/On
To select the sync mode between Internal Sync.(LL off) and Line-Lock
(LL on).
Set the line-lock off, the camera will synchronize to the internal time base.
Set the line-lock on, the camera’s vertical synchronization can be driven by
the AC signal in the power lines.
The default setting is Off
Note: Line-Lock sync mode operation is possible only when used with an
AC power source; it’s not possible with a DC power source.
