Installation
Notes
 Do not grasp the camera head when carrying the camera.
 Do not turn the camera head manually. Doing so will likely result in the
camera malfunctioning.

Turn off the power of ceiling unit before installing or removing the camera to
the ceiling unit.
Installing the Camera on a Ceiling
You can view the image of this camera in the normal direction when the camera
is installed on the ceiling.
There are three ways to install the camera:

Install directly on a ceiling.
 Use the existing junction box.
 In places you cannot use screws on the ceiling or in case you do not want the
camera to stand out, use the optional in-ceiling bracket YT-ICB124.
For details, see the installation instructions of YT-ICB124.

Install the camera to a horizontal ceiling. If you have to install the camera to an
incline, make sure the incline is within ±15° to the horizontal level to ensure the
turning performance of the camera.
WARNING

If you attach the camera in a high location such as wall or ceiling, etc., entrust
the installation to an experienced contractor or installer.

If you install the camera in a high location, ensure that the ceiling is strong
enough to withstand the weight of the camera plus the ceiling brackets and
then install the camera securely. 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.
Before installation

After deciding the direction in which the camera will shoot, make the required
holes for the junction box, and connect the cables.
 Remove the cable cover to wire the cables from the side of the camera.
Installing directly on a ceiling
Using the supplied template, make a hole for the wiring (ø100 mm (4 inches)).
Determine the location of the three screw holes for attaching the ceiling unit. 
Using the existing junction box
/ )
1
8
Attach the ceiling bracket to the junction box in the ceiling.
Screws for this operation are not supplied.
Attach the ceiling bracket in a manner that the triangular mark faces the front
side of the camera.
Fixing screws
The ceiling unit has three holes (ø5 mm ( /

the ceiling unit on the ceiling.
Required screws (not supplied) vary in accordance with the location or material
of the installation.
For steel: Fix with M4 screws and nuts.
For wood: Fix with tapping screws (nominal diameter 4). A material thickness of
15 mm ( / inches) or more is necessary.
19
32
For a concrete wall: Fix with dry bit or plug bolts.
For a junction box: Fix with screws that accommodate the screw holes in the
junction box.
WARNING
Use the appropriate screws in accordance with the condition and material of the
location site. Otherwise, the ceiling unit may fall and cause serious injury.
How to install the ceiling unit 
1
Attach the provided wire rope to the ceiling or junction box.
Use screws (not supplied) that accommodate the screw holes in the ceiling or
junction box.
2
Connect the cables.
3
Fix the wire rope on the wire rope hole in the ceiling attachment side of the
ceiling unit, using the supplied screws (M4×10).
Notes

Make sure other cables are not caught in the wire rope when fixing the
wire rope.
 When drawing out cables from the side of the camera, draw them through
the groove in the ceiling attachment surface of the ceiling unit. ()
4
Attach the ceiling unit on the ceiling or ceiling bracket.
Attach the cable screws to the unit temporarily. Then securely tighten all screws.
Notes
 Use the supplied screws to attach the ceiling bracket.
Using other screws does not ensure proper attachment and may cause the
ceiling unit to fall.

Ensure that the cables are not caught between the ceiling unit and camera
when drawing out the cables from the side of the camera.
How to install the camera 
1
Draw out the built-in wire rope from the camera and hook it on the wire rope
attachment hook of the ceiling unit.
2
Align the marks and insert the camera into the ceiling unit until you hear a
click.
3
Push in the two LOCK buttons and ensure that the camera is properly
installed.
Note
If you cannot press the LOCK buttons or if the buttons protrude from the
ceiling unit, the camera is not properly installed. Insert the camera into the
ceiling unit fully and press the lock buttons again to check if the installation
is proper.
In order to lock the RELEASE button, install a RELEASE button protector.
Note
Torque the screws to 0.5 N•m (4.9kgf•cm) or less to tighten them.
Tightening the screws too much may cause damage to the RELEASE button
protector.
Removing the camera 
1
Remove the camera while pressing the two RELEASE buttons on both sides at
the same time.
If a RELEASE button protector is installed, remove it.
Note
Always hold the camera when you press the RELEASE buttons. This will
prevent any risk of the camera falling.
Connection
Connecting to the Network
Connect the LAN port of the camera unit to a router or hub in the network using
the network cable (straight, not supplied).
To connect to a computer
Connect the LAN port of the camera unit to the network connector of a
computer using the network cable (cross, not supplied).
Connecting the Power Source
The following two methods are available for connecting to a power source.

12 V DC
 24 V AC
Connecting to a 12 V DC or 24 V AC power source supply
Connect the 12 V DC or 24 V AC power supply system to the power input
terminal of the camera.

Use a 12 V DC or 24 V AC power source isolated commercial power supply.

The usable voltage range is as follows:
12 V DC: 10.8 to 13.2 V
24 V AC: 21.6 to 26.4 V

Use a UL cable (VW-1) for 12 V DC or 24 V AC connection.
