Do not clean the CCD with strong or abrasive detergents. Use lens tissue or a
cotton tipped applicator and ethanol.
.. Never face the camera towards the sun.
Permanent damage may occur when subjected to intense light. Whether the
camera is in use or not. Use cautiously when operating any electrical device.
Keep the camera out of the direction of spotlights and light reflecting objects.
.. Do not operate the camera beyond the specified temperature, humidity
or power source ratings.
Do not use the camera in an extreme environment where high temperature or high
humidity conditions exist. Use the camera under conditions where temperatures
are within -10Ž ~ + 50Ž , and humidity is below 80% relative humidity. The
input power source is 220V ~ 240V AC for AC230V model and DC12V/AC24V ±
20% for AC24V model camera.
.. Do not touch the CCD sensor with your fingers. If necessary, use soft
cloth moistened with alcohol to wipe off the dust.
.. When the camera is not in use, keep the cap on the lens to protect the
Qualified service personnel or system installers should make the installation. Check
the power is OFF before handling the power cable no matter AC main power or low
A. Main Power Model (100VAC-240VAC 50Hz) :
1. Connect the AC power cord (supplied as standard accessory) to the power cord
socket of the camera.
2. Connect the AC power cord to an electrical outlet of AC100V ~ AC240V
.. Connect the power cord firmly. The power cord should be long enough for
panning and tilting. If the cable is too short, the power cord plug may be pulled
off the camera when the camera pans or tilts.
.. Brown: Live, Reference line lock. Blue: Neutral.
.. This camera voltage could accept range rated is AC90V ~ AC253V. But
recommend range is AC100V ~ AC240C.
B. Dual Power Model (12VDC/24VAC).
The series model has an AC/DC compatible input terminal. DC12V or AC24V
power supply cable can be connected to this terminal. The camera detects
the power source automatically.
Recommended wire gauge size. Ö0.65mm(AWG22), Stranded wire

1. 12V DC Power Supply
Connect the power cable to the AC/DC compatible input terminal on the rear
panel of the camera. +12VDC should connect is the RED terminal. 0VDC
to the white terminal. Black terminal for Earth connection.
2. 24V AC Power Supply
Connect the power cable to the AC/DC compatible input terminal on rear
panel of the camera.
.. If the cable is too short, the power cable may be pulled off the camera
when the camera pans or tilts.

2. Connect the lens cable to the auto iris lens connector on the rear panel of
Caution for Mounting the Lens
The lens mount should be a CS –mount (1”-32UN) and the lens weight should
be less than 450g (0.99 lbs). IF the lens is heavier, both the lens and camera
should be secured by using the supporter.
H. Focus and Back Focal Adjustment
The following adjustment should be made by qualified service personnel or
1. Loosen the screw of back focus
adjust on the topside of front
2. Move the back focus adjust screw to
the desired position.
3. Fixing the screws on the back focal adjusting screw.
Do not fix the back focus screw too tight, otherwise the back focus
mechanize unit might be damaged. Finger tight only. When the
C-mount lens is mounted, do not rotate the ring Counter clockwise by
force after it. If the ring is rotated by force, the inner lens or CCD
image sensor may be damaged.
