1. Do not install the camera near electric or magnetic fields.
Install the camera away from TVs, radio transmitters, magnets,
electric motors, transformers, and audio speakers as the magnetic
fields generated from these devices will distort the video image.
2. Do not install the camera in a high temperature environment.
Install camera away from stoves or other heat generating devices
as the high temperature could cause deformation, discoloration or
other damage to the camera. Install the camera where the
temperature range will stay between -40 ~ 122 degree Fahrenheit.
3. Never face the camera towards the sun.
Never aim the camera at the sun or other extremely bright objects
whether it is in use or not.
4. 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.
5. Heater
Heater elements can be very hot! Heaters are located inside the
camera housing and will activate automatically while the
environment temperature is below 50 degrees Fahrenheit. Do not
touch the heater element while it’s active.

3. Mounting the base.
Attach the base to the wall or ceiling; fix the base by the 4 setscrews
provided in the accessory pack. The dome weight is approximately 3.7 lbs,
please make sure if the mounting is strong enough to support the weight.
If not, please reinforce the mounting according to the environment.
Note: The diameter of the screw hole is 4.7mm.
Caution: To prevent moisture leaking into the housing, apply an
appropriate gasket or sealant around the conduit connection.

5. Wire Connection
Connect the power supply cable (AC24V/DC12V), video output and
alarm output to the proper connectors shown as Figure 7.
The V. Phase adjustment screw is located on the termination board.
The vertical phase may require adjustment to synchronize the vertical
phase of the camera with other cameras in the system when it is to be used
in the line-lock sync mode. Make sure the vertical phase adjustment of
the camera does not match other cameras.
Note: The inner part of power plug is positive. The pigtail wire with the white
stripe is positive.

6. View Angle Adjustment
The camera can be rotated 360°horizontally, 140°vertically and 60°
3’rd axis view angles (as shown in Figure 8). Adjust the proper camera
view angle as needed. If a vari-focal lens is used, you may adjust the
focus and zoom of the lens to bring the object in focus. Be sure to
loosen the locking screws on the lens before you do the adjustments.

7. Reposition the adjustment stick (only for 3.6-9mm Vari-focal lens)
a) The default position of adjustment stick is shown as below:

b) While zooming In/Out with the adjustment stick, it may obstruct
other adjustments of Iris Level and Video Output.
c) In this case, you can gently take off the adjustment stick and place
it to the other hole at its right-hand side. This will allow you to adjust
zooming function smoothly.

Dip Switch Functions
Vari-Focal Lens
LL (Line-Lock) OFF/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.
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.
The default setting is ON.
AGC (Automatic Gain Control) OFF/ON
AGC ON: Signal strength sensitivity automatically adjusts to the high or
low light conditions. The default setting is ON.
AGC OFF: This setting should be turned switched to in an environment
with a constant light source.

11
BLC (Back Light Compensation) ON/OFF
When BLC is turned ON, the AGC, ES and IRIS operating points are
determined by averaging over the center area instead of the entire
field-of-view, so that a dimly-lit foreground object at center area can be
clearly distinguished from brightly-lit backgrounds.
Dip Switch Functions
BLC should not be used unless it is needed to compensate a subject with a
light behind it.
The default setting is OFF.
FL (Flickerless Function) ON/OFF
When picture flicker fiercely, turn FL on, then the camera will stabilize the
speed of electronic shutter at 1/100(PAL) or 1/120(NTSC) automatically,
and reduce the flicker immediately.
The default setting is OFF.
IRIS Level Adjustment
Brightness Level can be adjusted from the IRIS level VR.
Turn counterclockwise to L to get darker picture.
Turn clockwise to H to get brighter picture.
IRIS ALC Adjustment
To select light metering method – This settting adjusts the gain and iris level
simultaneously.
Turn the IRIS ALC Adjustment VR counterclockwise for Average
Metering.
Turn the IRIS ALC Adjustment VR clockwise for Peak Metering. Too
high of a setting will result in a noisy picture.
