Design and specifications are subject to change without notice.

Always verify that the unit is operating properly before use. SONY WILL
NOT BE LIABLE FOR DAMAGES OF ANY KIND INCLUDING, BUT
NOT LIMITED TO, COMPENSATION OR REIMBURSEMENT ON
ACCOUNT OF THE LOSS OF PRESENT OR PROSPECTIVE
PROFITS DUE TO FAILURE OF THIS UNIT, EITHER DURING THE
WARRANTY PERIOD OR AFTER EXPIRATION OF THE
WARRANTY, OR FOR ANY OTHER REASON WHATSOEVER.

Some of the parts that make up this product (electrolytic condenser,
for example) need replacing regularly depending on their life
expectancies. The lives of parts differ according to the environment
or condition in which this product is used and the length of time it is
used, so we recommend regular checks.
Consult the dealer from whom you bought it for details.

After deciding the direction in which the camera will shoot, make the
required hole (ø 40 to 60 mm (ø 1 

5

/

8

 to 2 

3

/

8

 inches)) for the connecting

cables using the supplied template. Then decide the two mounting hole
positions to install the camera. (D)

The camera is provided with two ø 5 mm (

7

/

32

 inch) mounting holes. Install

the camera on a ceiling or wall with screws.
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.
Wood wall or ceiling: Use M4 tapping screws. The panel thickness must
be 15 mm (

5

/

8

 inch) or more.

Concrete wall: Use appropriate anchors, bolts and plugs for concrete walls.
Junction box: Use screws to match the holes on the junction box.

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.

Remove the dome casing. (E)

1

Pull out the screw cover and loosen the screw with a Phillips
screwdriver.

2

Turn the dome casing to the curved mark position on the camera unit,
and remove the dome casing from the camera unit. When the screw
is caught on the screw hole, pull up the screw.

Remove the slit cover.

Remove it expanding the slit cover. (F)

When installing on a ceiling or wall, fix the supplied wire rope to the
bottom of the camera and the ceiling (or wall). (G)

1

Fix the wire rope with the supplied shoulder screw to the hole for the
wire rope on the bottom of the camera.

2

Fix the wire rope to the ceiling or wall.

Install the camera on the ceiling or wall with the two screws. (G)

• If you want to install the camera at a height such as on a ceiling,

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 10
kg (22 lb 1 oz) or more, and then install the camera securely. If they
are not strong enough, the camera may fall and cause serious injury.

• To prevent the camera from falling, be sure to attach the supplied wire

rope.

• If you install the camera at a height, check periodically, at least once a

year, to ensure that the connection has not loosened. If conditions
warrant, perform this periodic check more frequently.

If you cannot use screws on a ceiling or wall, or if you want to hide the
camera to be less conspicuous, use the YT-ICB45 in-ceiling bracket
(optional) with which you can mount the camera on the ceiling.

H

Loosen the camera head fixing screw.

Adjust the camera to turn the lens in the desired direction.

Tighten the camera head fixing screw to fix the camera.

Loosen the lens ring fixing screw.

Turn the zoom ring to adjust the angle of view.

Turn the focus ring to adjust the focus.

Tighten the lens ring fixing screw to fix the zoom and the focus.

Repeat steps 1 to 7 until the coverage and the focus are determined.

• When you adjust the camera head angle without loosening camera

head fixing screw, an internal metallic part may be damaged.

• If the camera head is too heavy to be adjusted, loosen the camera

head fixing screw until it moves freely.

• When the lens is not put in the slit of the camera head holder, the

moving range of the camera head is limited.

• Do not turn the lens more than 360 degrees. As this may damage the

wiring inside.

• There are three screw holes for fixing the lens ring at 120 degree

intervals. If the lens ring fixing screw poses a problem for adjusting the
camera direction and coverage due to the direction of the camera
head, detach the screw and reattach it to another screw hole, then
adjust the camera direction and coverage again.

• 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.

Attach the slit cover. (I)

• The proper position of the slit cover is slightly apart from the camera

mount. Do not push in by force.

• If you cannot attach the slit cover because the barrier of the lens ring

fixing screw prevents it, attach the lens ring fixing screw to another
screw hole. There are three screw holes for the lens ring fixing screw
on the concentric circle.

Fix the dome casing and the camera unit. (J)

1

 Align the carved mark on the dome casing with that on the camera

unit, and turn the dome casing in the direction of the arrow.

2

 Secure the screw and put the screw cover.

K

Using a commercially available network cable (straight), connect the LAN
port of this unit to a hub in the network.

Using a commercially available network cable (cross), connect the LAN port
of this unit to the network connector of a computer.

There are three ways to supply the power source to this product, as follows.
• 12 V DC
• 24 V AC
• Power supply equipment pursuant to IEEE802.3af (PoE* system)

*PoE means Power over Ethernet.

If the power is supplied from the power input terminal and LAN port at the
same time, the power from the LAN port has priority over the other.

Connecting to 12 V DC or 24 V AC source (L)

Connect the AC power cord to the 12 V DC/24 V AC connector on the rear
and a 12 V DC or 24 V AC source.
• Use a 12 V DC or 24 V AC source isolated from 100 to 240 V AC. Each

usable voltage ranges are as follows.
12 V DC: 10.8 V to 13.2 V
24 V AC: 21.6 V to 26.4 V

• Use UL cable (VW-1 style 1007) for these connections.

The power supply equipment pursuant to IEEE802.3af supplies the power
through a LAN port. For details, refer to the Instruction Manual of the
equipment.
