Panasonic WV-CW974 Mode D'emploi page 9

• In a motor vehicle, on a boat, or other areas subject
to strong vibration (This camera is not designed for
use in a vehicle.)
• Near an air conditioner outlet or any areas subject to
sudden changes in temperature. (Such conditions
can cause clouding and condensation formation on
the dome cover.)
Remove the protective sheet from the dome cover
after the installation work is complete.
Wiring power to the camera
The camera does not have a power switch. During the
electrical work, configure the power supply to the
camera so it can be turned on and off.
Noise interference considerations
When using a power line that is greater than 120 V AC
and wiring that is longer than 1 meter, wiring should be
routed using a separate metal conduit. (The metal
conduit must be earth grounded.)
Important:
• Before setting up the camera for a configuration
where the camera's RS485 data port is used for
camera control (pan, tilt, etc.) by the system
controller, the camera's DIP switches must be
configured to specify the unit number and
communication parameters. (page 13)
If DIP switch setting is not performed, the
system controller control will not be possible
and camera setup will have to be performed
again. Be sure to check the DIP switch settings
before setting up the camera.
Note: If you need to connect a ground, be sure to do it
before you connect the main power. Also, when removing
the ground, be sure to disconnect the main power.
Beware of high humidity.
If the camera is installed when humidity is very high,
moisture may collect in the camera and cause the
dome to become foggy. If the dome becomes foggy,
remove it when the humidity is low and eliminate the
moisture inside the camera, and then replace the
dome. (page 6, 7)
About the heater
The camera comes with a built-in heater so it can be
used in cold regions. The heater automatically turns on
when the internal temperature goes below 10 °C {50
°F}. However, snow and frost that collect on the dome
cover may not melt if the temperature falls below -40
°C {-40 °F}. Care needs to be taken regarding the
ambient and internal temperature when using the
camera in cold regions.
About effects on image quality
The camera does not have a wiper. If the camera is
installed in the following conditions image quality may
deteriorate or the image may be invisible.
(1) In the rain
The picture may be hard to see if the wind blows
rain onto the dome cover while it is raining.
(2) In the snow
When it snows, snow may collect on the dome
cover and block some of the picture. (The amount
of snow that collects on the dome cover depends
on the quality and amount of the snow.)
(3) Effects of dust and automobile exhaust
Airborne dust and automobile exhaust, from the
location where the camera is installed, may cause
dirt to build up on the dome cover and reduce the
quality of the picture.
Important hints to help with the installation
• A self-cleaning function is activated (PAN/TILT/
ZOOM/FOCUS) when the camera is turned on.
• There is a limit to the number of devices that can be
put together in one configuration. Check the ratings
and outer dimensions before hooking up the
devices.
