may incur injury and cause damage to peripheral objects in the
immediate surroundings.

The WAT-221S/231S is designed to be used safely; however, it may lead to
a physical accident caused by fire and electric shock if not used correctly.
Therefore, please keep and read the “Cautions for safety” for protection
against accidents.

•

Do not disassemble and/or modify the WAT-221S/231S.

•

Do not operate the WAT-221S/231S with wet hands.

•

Use a stabilized power adaptor designed for DC+12V±±±±
10%, with a current capacity of more than 250mA for the

War ning

221S/231S.

The recommended voltage is DC+12V±10%

•

Do not expose the WAT-221S/231S to wetness or high
moisture conditions.

The WAT-221S/231S is designed and approved for indoor use
only. The WAT-221S/231S is not water-resistant or waterproof.
If the location of the camera is outdoors or in an outdoor like
environment, we recommend that you use an outdoor camera
housing.

•

Protect the WAT-221S/231S from condensation.

Keep the WAT-221S/231S dry at all times during storage and
operation.

•

Should the camera not work properly, switch off the power
immediately. Then check the camera according to the
“Problems and Trouble shooting” section.

•

Cau tion

Avoid the striking of hard objects or dropping the WAT­221S/231S.

The WAT-221S/231S uses high quality electrical parts and
precision components.

•

Do not connect any power supply directly to the video out
terminal of the unit.

Do not connect the WAT-221S/231S with any monitor using a
video/power single transmission terminal. The WAT-221S/
231S is not designed for use with this type of equipment. We
also advise you to read the operation manual of the monitor
you plan to use before any connections are made.

•

Do not install the WAT-221S/231S in a position subject to
direct sunlight.

Sunlight shinning directly onto the WAT-221S/231S lens can
cause damage to the CCD.

•

Select a stable place for installation of the WAT-221S/
231S.

Use a support of durable strength around an installation
position on a ceiling or wall when a camera stand or tripod is
used.

•

Do not move the WAT-221S/231S with the cables con­nected.

Before moving the WAT-221S/231S, always remove the video
cable and power cable from the rear of the camera first.

Problems and Trouble Shooting

If any of the following problems occur when using the WAT-221S/
231S,

•

An optimal picture cannot be obtained, after checking that all the cables
and connections are correctly in place

•

Smoke or any unusual odor emerges from the WAT-221S/231S.

•

An object becomes embedded or a quantity of liquid seeps into the camera
housing

•

•

Disconnect the camera immediately according to the following procedures:

More than the recommended voltage or/and amperage has been applied
to the WAT-221S/231S by mistake

An yt hing unusu al occ urrin g t o any equ ipment c onnecte d t o th e
WAT-221S/231S.

①Switch off the main power supply to the camera.
②Remove the power and video cables connected to the WAT-221S/231S.
③Contact the distributor or dealer from which the WAT-221S/231S was

purchased.

Power Supply

Use a stabilized power adaptor designed for DC+12V±10%, with a current
capacity of more than 250mA.
Use the optional DC plug if the shape or polarity of the DC plug of the power
adaptor to be used is not compatible with the camera (See the drawing on
the right below).

War ning

Cau tion

The wiring on the connector must be exact.
Be careful no to touch the other terminal while wiring.
Protect the wiring portion by using insulation tape
after wiring. If the above care and attention is not
adhered to, damage to the WAT-221S/231S and
power adaptor may occur and may also cause fire.

Auto-iris Lens

Before connecting the auto-iris lens, please make sure that the pin
configuration is correct by checking with the following table. If the
configuration of your iris connector is different from the following, the plug
and pins will need to be rewired.

Set-up and Operation

1) Ensure that the power to the WAT-221S/231S and the peripheral
equipment is turned off before making any connections.

2) Remove the lens mount cap from the WAT-221S/231S and attach the
CS-mount lens. Use the optional C-mount adaptor (34CMA-R) when a
C-mount lens is used.

3) Connect the iris control cable to ⑤AUTO-IRIS SOCKET on the WAT-
221S/231S when an auto-iris lens is being used.

4) Connect ⑩VIDEO OUT on the WAT-221S/231S with the monitor, using
a coaxial cable with 75Ω impedance, such as an RG-58/U or an RG-6/U.
If the monitor has an S-terminal, high resolution imaging is possible by
connecting with ⑪Y/C OUT.

※The ⑪Y/C OUT can be used together with the ⑩VIDEO OUT.
※Select a monitor with the same television system as the WAT-221S/

231S NTSC or PAL. A monitor with more than 500TV lines is
recommended.
