Installing the camera
Step 1: Connecting the cables
1. Connect the BNC cable to the BNC connector
(11).
2. Connect the power supply cable to the power
connector (12).
You can use 24 V AC or 12 V DC connection.
Caution
If using a DC supply, make sure the polarity is
correct. Incorrect connection may cause
malfunction and/or damage to the video
camera.
3. Guide the cables through the cable entry holes
(1).
Step 2: Mounting the camera
1. Place the template on the mounting surface
and mark the holes.
2. Drill two holes as marked.
3. Insert the wall plugs into the holes.
4. Fasten the unit with the screws provided.
Step 3: Adjusting the camera position
1. Hold the lens so that it does not rotate.
2. Loosen the locking ring (13) and panning
adjustment wheel (14).
Caution
Do not loosen the locking ring without holding
the lens in place. Otherwise the lens may rotate
with the locking ring and the cable may twist.
3. Turn the lens and axial ring (15) in the desired
direction.
Note
If the camera does not rotate smoothly, loosen
the locking ring completely. The locking ring has
an internal stop and will not come off.
Caution
Do not turn the lens more than 360° as this may
cause internal cables to disconnect or break.
4. Lightly tighten the locking ring (13) and panning
adjustment wheel (14)
Step 4: Adjusting zoom and focus
1. Loosen the zoom lever/locking screw (4) by
turning it counter-clockwise.
2. Rotate the zoom ring to achieve the desired
picture.
3. Loosen the focus lever/locking screw (5) by
turning it counter-clockwise.
4. Rotate the focus ring to adjust the focus.
5. If readjustment is necessary, repeat the steps
above.
6. Retighten the zoom lever/locking screw (4) and
the focus lever/locking screw (5).
Caution
Retighten the locking screws to prevent loss of
adjustment.
7. Hold the lens and tighten the locking ring (13)
and panning adjustment wheel (14).
Optional settings
• Adjust the brightness of the picture using the
LEVEL screw (6):
L = low, makes the picture darker
H =high, makes the picture brighter
• Adjust the phase difference between cameras
(use V Phase adjustment screw (7).
• Set DIP switches (8) to activate or deactivate
the following features:
• Backlight compensation (BLC)
• Automatic gain control (AGC).
Automatically adjusts the picture to suit
ambient brightness
• Line Lock (LL).
Sets camera synchronisation to internal
(OFF) or line lock (ON). Line lock is only
available with 24 V AC.
The DC/AES DIP switch is not in use.
Step 5: Attaching the dome to the unit
Note
Use a soft lint-free cloth to wipe the dome cover
clean and remove fingerprints.
1. Clean the joint surfaces of the unit.
2. Place the dome on the unit (see figure C).
3. Turn the dome clockwise and lock the cover in
place.
General guidelines
Operation and storage
• Avoid filming very bright objects (such as light
fittings) for an extended period.
• Do not operate or store the unit in the following
locations:
• Extremely hot or cold places.
• Close to sources of strong magnetism.
• Close to sources of powerful
electromagnetic radiation, such as radios or
TV transmitters.
• In humid or excessively dusty places.
• Where exposed to mechanical vibrations.
• Close to fluorescent lamps or objects
reflecting light.
• Under unstable or flickering light sources.
Cleaning
• Use a soft, dry cloth to remove fingerprints or
dust from the dome.
• If the dome is very dirty, use a small amount of
mild detergent on a damp cloth for cleaning.
Ensure the dome is dry before attaching the
dome to the unit.
Caution
Do not use volatile solvents such as alcohol,
benzene or thinners. These solvents may
damage the surface.
Transportation
Use the original packing material or materials of
equal quality.
CCD characteristics
The following conditions may be observed when
using a CCD camera. These are inherent of the
design and do not stem from any fault within the
camera itself.
• Vertical smear: This phenomenon occurs when
viewing a very bright object.
• Patterned noise: This is a fixed pattern which
may appear over the entire monitor screen
when the camera is operated at a high
temperature.
• Jagged picture: When viewing stripes, straight
lines, or similar patterns, the image on the
screen may appear jagged.
