Connecting the Cables to the Camera
Before installation, connect the supplied cables to the camera as required for
your usage and wire them.
1 Remove the dome casing.
Loosen the four fixed screws of the dome casing using the supplied wrench
and lift the dome casing.
2 Pass the cables through the conduit hole on the bottom of the camera
unit.
When you route the cables from the side of the camera unit, see “Connecting
to the side conduit hole”.
3 Connect the cables to the connectors on the camera unit.
I/O cable: to EXT CTRL connector
BNC cable: to VIDEO OUT connector
Audio cable: to AUDIO IN connector
4 Pass the cables through the guides to secure the cables. (-4)
5 Pull the cables gently from the bottom of the camera unit to take in the
slack.
Connecting to the side conduit hole
The cables are set up at the factory to pass through the bottom conduit hole. If
you want to use the side conduit hole, perform the following steps:
Remove the conduit hole cover.
Disconnect the cables from the connectors, and pull them out from the
bottom conduit hole.
Insert the cables through the side conduit hole, and connect the cables to
their respective connectors.
Pass the cables through the guides to secure the cables. (-5)
Attach the conduit hole cover that was removed from the side conduit hole
to the bottom conduit hole.
Notes
If the bottom conduit hole is dirty, the conduit hole cover cannot be fixed
firmly. In this case, moisture may leak into the casing and this may cause
a malfunction. Wipe off the dust with a soft cloth, and fix the conduit hole
cover firmly.
Cover the joint part of the pipe/cover with silicon sealant, etc. to prevent
moisture from getting inside the casing.
When you install the camera on a wall lengthwise, position the side conduit
hole directly below to prevent moisture from getting inside the casing. (-1)
Use a pipe/plug with a thread length of 12 mm (
1
/
2
inch) or less so that it does
not damage the camera. (-2)
Installation
WARNING
If you attach the camera in the height such as the wall or the ceiling, etc.,
entrust the installation to an experienced contractor or installer.
If you install the camera at a height, ensure that the installation location and
its material are strong enough to withstand a weight of 15 kg (33 lb 11 oz) or
more, and then install the camera securely. If they are not strong enough, the
camera may fall and cause serious injury. If the ceiling is not strong enough,
the camera may fall and cause serious injury.
To prevent the camera from falling, make sure to attach the supplied wire rope.
If you attach the camera to the ceiling, check periodically, at least once a year,
to ensure that the connection has not loosened. If conditions warrant, make
this periodic check more frequently.
Deciding the Installation Location of the Camera
After deciding the direction in which the camera will shoot, make the required
hole (ø73 mm (2
7
/
8
inches)) for the connecting cables using the supplied
template. Then decide the four mounting hole positions to install the bracket.
Mounting screws
The supplied bracket is provided with eight ø4.5 mm (
3
/
16
inch) mounting holes.
Install the bracket on a ceiling or wall with screws through four mounting holes:
two 83.5 mm (3
9
/
32
inch)-pitched holes or four 85.7 mm (3
3
/
8
inch)-pitched
holes. The required mounting screws differ depending on the installation
location and its material. (Mounting screws are not supplied.)
Steel wall or ceiling: Use M4 bolts and nuts.
Wooden wall or ceiling: Use M4 tapping screws. The panel thickness must be
15 mm (
5
/
8
inch) or more.
Concrete wall: Use anchors, bolts and plugs suitable for concrete walls.
Junction box: Use screws to match the holes on the junction box.
WARNING
The required mounting screws differ depending on the installation location and
its material. If you do not secure the camera with the appropriate mounting
screws, the camera may fall off.
Installing the Camera
1 Install the supplied bracket on the ceiling or wall.
Refer to “Mounting screws” for screws to be used.
2 Fix the supplied wire rope to the camera unit and the ceiling or wall.
Fix the wire rope with the supplied Screw
M4 × 8 to the hole for the
wire rope on the bottom of the camera unit.
Fix the wire rope to the ceiling or wall.
When you install the camera on a wall, feed the cables through it. (
-1)
3 Attach the camera unit to the bracket with the supplied four screws.
The screws have a fall-prevention mechanism. The screws inserted into the
screw holes of the camera unit do not fall even if you turn the camera unit
upside down.
Insert the two holders to any two of the grooves on the bracket.
Turn the camera clockwise until the locating pins snap to the holes on the
holders. Then the four camera installation holes will align the projections on
the bracket accordingly. There are four projections with an angle of
90 degrees, so you can select one of four directions.
Then tighten the four camera unit mounting screws to attach the camera
unit to the bracket through the camera installation holes.
Note
If you cannot use screws on a ceiling or wall, or if you want to make the camera
less conspicuous, use the YT-ICB45 in-ceiling bracket (optional) with which you
can mount the camera on the ceiling.
For this model, install the camera to the position on the side brackets of
YT-ICB45. Refer to the Installation Instructions of YT-ICB45 for detail information.
Adjusting the Camera Direction and Coverage
1 Loosen the camera head fixing screw.
2 Adjust the camera to turn the lens in the desired direction.
3 Tighten the camera head fixing screw to fix the camera.
4 Slide the ZOOM/FOCUS switch to W/T to adjust the zoom.
The zoom indicator is displayed on the monitor.
5 Press the Easy Focus button to automatically adjust the focus.
6 Repeat steps 1 to 5 until the coverage and the focus are determined.
Notes
When you adjust the camera head angle without loosening camera head
fixing screw, an internal part may be damaged.
When the lens is not put in the slit of the camera head holder, the moving
range of the camera head is limited.
If the camera head is too heavy to be adjusted, loosen the camera head fixing
screw until it moves freely.
When adjusting the angle, be sure that the TOP mark on the camera head
section faces the ceiling. If the camera is installed with the TOP mark facing
the floor, the image appears upside down.
If you cannot achieve satisfactory focus with the Easy Focus button due to the
shooting environment, slide the ZOOM/FOCUS switch level to N/F to focus
manually. The focus indicator is displayed on the monitor.
Poor focus may also be caused by the dome case assembly. Readjust the
focus using the system menu.
For details, refer to the User Guide of the equipment.
Note
Do not turn the lens more than 360 degrees, as this may damage the wiring inside,
which may cause failure on video output.
Attaching the Dome Casing
Fix the dome casing and the camera unit.
Align four screw holes on the dome casing with that on the camera unit, and
tighten four screws with the supplied wrench to secure the dome casing.
Note
Make sure that the cord does not get caught between the dome casing and the
unit casing. Rotate the cord and adjust the position of the cord.
