The definitions of t he symbols used in this operation manual are:

When you do not adhere to or take notice of the “Danger” sign, it
may lead to a serious accident such as death or injury caused by fire
or electric shock.

When you do not adhere to o r take notice of the “Warning” sign, it
may cause severe damage such as a physical injury.

When you do not adhere to o r take notice of the “Caution” sign , it
may incur injury and cause damage to peripheral objects in the
immediate surroundings.

Cautions for Safety

The WAT-902HB series 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” below for protection
against accidents.

• Do not disassemble and/or modify the WAT-902HB series.

• Do not operate the WAT-902HB series with wet hands.

• Use a stabilized power adaptor designed for DC+12V±10%,

with a current capacity of more than 250mA for the
WAT-902HB series.

The recommended volta ge is DC+12V±10%

• Do not expose the WAT-902HB series to wetness or high

moisture conditions.

The WAT-902HB series is designed and approved for indoor use
only. The WAT-902HB series is not water-resistant or waterproof. If
the location of the camera is outdoors o r in an outdoor like
environment, we recommend that you use an outdoor camera
housing.

• Protect the WAT-902HB series from condensation.

Keep the WAT-902HB series dry at all times durin gstorage and
operation.

• Should the camera not work properly, switch off the power

immediately. Then, check the camera according to the“Probl ems
and Trouble shooting”s ection.

• Avoid the striking of hard objects or dropping the WAT-902HB
series.

The WAT-902HB series uses high quality e lectrical parts and
precision components.

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

Do not connect the WAT-902HB series with any monitor using a
video/power single tra nsmission terminal . The WAT-902HB series
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-902HB series in a position subject to
direct sunlight.

Sunlight shinning directly onto the WAT-902HB series lens can
cause damage to the CCD.

• Select a stable place for installation of the WAT-902HB series.

Always fix the camera securely. See【Mounting Holes】section.

• Do not move the WAT-902HB series with the cables
connected.

Before moving t he WAT-902HB series, always remove the v ideo
cable and power cable from the camera first.

• Avoid using the WAT-WAT-902HB series near any strong

electromagnetic field.

After installing i nto main equipment, if the WAT-9 02HB series is
exposed to electromagnetic waves causing the monitored image to
become distorted, we recommend the camera be shielded by
appropriate pr otective casing.

Problems and Trouble Shooting

If any of the following problems occur when using the WAT- WAT-902HB
series,

• An optimal picture cannot be obtained, after checking that all the cablesand

connections are correctly in place

• Smoke or any unusual odor emerges from theWAT -902HB series

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

• More than the recommended voltage or/and amperage has been applied to the

WAT-902HB series by mistake

• Anything unusual occurring to any equipment connected to the WAT-902HB
series.

Disconnect the camera immediatel y according to the following procedures:

①Switch off the main power supply to the camera.
②Remove the power and video cables connected to the WAT-902HB series.
③Contact the distributor or dealer from which the WAT-902HB series wa s

purchased.

Power Supply and Wiring

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

The wiring on the connector must b e exact.
Be careful not to touch the other terminals while wiring. Protect the wired portion
by using insulation tape. If the above care and attent ion is not adhered to,
damage to the WAT-902HB series and power adaptor may occur and may also
cause fire.

Mounting Holes

As shown in the figure on the right. The WAT-902HB series
provides four mounting holes(φ2.2mm), one in each corner of
the circuit bo ard. Fix the unit secure ly using M2 screws. Once
the board is secured proceed with the following steps below.

Set-up and Operation

1) Ens ure that the power to the WAT-902HB series and the peripheral equipment
is turned off before making any connections.

2) R emove the lens mount cap f rom the WAT-902HB series.

3) Wh en an auto iris lens is being used, connect the cable to ⑤TERMINAL FOR
AUTO-IRIS LENS.
※Do not connect a DC cont rol iris lens to this camera.

4) Connect the attached cable to ④POWER IN/VIDEO OUT. See the【Power
Supply and Wiring】section.

5) Connect a coaxial cable with 75Ω impedance, such as an RG-58/U or an
RG-6/U to the monitor. Select a monitor with the same television system as
the WAT-902HB series: EIA or CCIR. A monitor with more than 600TV lines is
recommended.

6) Turn on the power to the WAT-902HB series, monitor and all other allied
equipment. When a p icture cannot be obtained on the monitor, check and
follow the procedure mentioned in the【Problems and Trouble Shooting】
section.

7) After following the procedure below and the picture is still out of focus, open
the iris fully a nd loosen ③FOCUSING ADJUSTMENT SCREWS with the hex.
wrench and move the lens forwards until a clear picture is obtained.

Manual Lens

Adjust the focus and iris to the best position on
the lens.

Video Auto-iris Lens Adjust the f ocus on the lens.

8) S et the AGC mode by ⑦AGC SELECTION SWITCH.

Mode Range Effect

HI

5～50dB

・When minimum il lumination is more

important than the SN ratio
(Surveillance in a low light environment)

LO

5～32dB

・When SN ratio is more important than

minimum illumination.

・When adequate lig hting is present or a

stable lighting condition is availabl e.

Function Setting
