Operation Manual

This Operation Manual covers safety, camera functions, installation and the
correct operating procedure for the WAT-232S. First, we ask you to read this
Operation Manual thoroughly, then install and operate the WAT-232S as advised.
In addition, for future reference, we also advise safekeeping of this manual.

Please contact the distributor or dealer from which the WAT-232S was
purchased, if you do not understand the installation, operation or safety
instructions laid out in this manual. Not understanding the contents of the
Operation Manual sufficiently may cause damage to the camera.

immediate surroundings.

Cautions for Safety

The WAT-232S is designed to be used safely; however, if not used safely, it may
lead to a physical accident caused by fire and electric shock. Therefore, please
keep and read the “Cautions for safety” for protection against accidents.

•

Do not disassemble and/or modify the WAT-232S.

•

Do not operate the WAT-232S with wet hands.

•

Use a stabilized power adaptor designed for DC+12V±±±±10%,
with a current capacity of more than 250mA for the WAT-232S

The recommended voltage is DC+12V±10%.

•

Do not expose the WAT-232S to wetness or high moisture
conditions.

The WAT-232S is designed and approved for indoor use only. The
WAT-232S 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-232S from condensation.

Keep the WAT-232S 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.

•

Avoid the striking of hard objects or dropping the WAT­232S.

The WAT-232S 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-232S with any monitor using a
video/power single transmission terminal. The WAT-232S 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-232S in a position subject to direct

sunlight.

Sunlight shinning directly onto the WAT-232S lens can cause
damage to the CCD.

•

Select a stable place for installation of the WAT-232S.

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-232S with the cables connected.
Before moving the WAT-232S, always remove the video cable and
power cable from the rear of the camera first.

•

Avoid using the WAT-232S near any strong electromagnetic
field.

After installing into main equipment, if the WAT-232S is exposed to
electromagnetic waves causing the monitored image to become
distorted, we recommend the camera be shielded by appropriate
protective casing.

Set-up and Operation

1) Ensure that the power to the WAT-232S and the peripheral equipment is
turned off before making any connections.

2) Remove the lens mount cap from the WAT-232S 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-232S
when an auto-iris lens is being used.

4) Connect ⑦VIDEO OUT on the WAT-232S 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 ⑩
Y/C OUT.

※The ⑩Y/C OUT can be used together with the ⑦VIDEO OUT.
※Select a monitor with the same television system as the WAT-232S NTSC

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

5) Insert the power plug of the power adaptor into ⑫POWER IN on the back
panel of the WAT-232S. Confirm that the power adaptor is not connected to
the power supply before insertion of the power plug into ⑫POWER IN.

6) Turn on the power to the WAT-232S, monitor and all other allied equipment.
When a picture cannot be obtained on the monitor, or a problem occurs,
check and follow the procedure mentioned in the【Problems and Trouble

Shooting】section.

BUTTON. The WAT-232S is manufactured using high-grade CCD devices
that are selected by tough standards by the manufacturer. However, it is
impossible to prevent the white blemishes from occurring after shipment
because the white blemish phenomena can be caused by cosmic rays. The
WAT-232S has a white blemish correction circuit to help control the white
blemish phenomena. Correct according to the following procedures, if white
blemishes are present.

[PROCEDURE]

1. Completely cover the lens to prevent light entering.

2. Press the ⑮WHITE BLEMISH CORRECTION BUTTON using a fine

stick.

3. After 5 seconds, the white blemishes are automatically detected, and
then recorded to the camera.

※Make sure that the lens is completely shielded from light before correction

of the white blemishes. If the lens is not covered properly and light can
enter into the lens on to the CCD face, the correction of the white blemish
may not be detected correctly.

■■■■Day/Night

WAT-232S has a day/night function that can change the day mode and night
mode by switching the IR-cut filter.

1) AUTO mode

In AUTO mode, DAY/NIGHT mode is automatically selected according to the
ambient luminance. In DAY mode, when the ambient luminance becomes dark
(the gain value of the AGC exceeds the set value), the camera becomes NIGHT
mode automatically. On the other hand, when the ambient luminance becomes
bright (the gain value of the AGC becomes less than the set value), DAY mode is
automatically selected. “Hunting (=continuous switching operation of day mode
and night mode)” does not occur easily because the gain value of the AGC at the
time of switching from day mode to night mode (A) is higher than the gain value
of the AGC at the time of switching from night mode to day mode (B).

The Day/Night switching point of the camera can be selected by ⑬FUNCTION
SWITCHES (2. D/N changing level selection switch). When sensitivity is more
important than the color image, set to LO(=OFF). When the color image is
preferred to a monochrome image, set to HI(=ON).

2) EXT mode

In EXT mode, DAY/NIGHT mode can change arbitrarily. The IR-cut filter can be
disabled (=night mode) by an applied voltage of 3 to 12V between the terminals
1 and 2 (current value: 0.7mA at 3V and 4.5mA at 12V). See the pin configuration
as follows.

correct when connecting the cables.
