Video Cable
1. It is recommended to use a monitor
whose resolution is at least equal to
that of the camera.
2. The maximum extensible coaxial
cable length between the camera
and the monitor is shown in the
table.
Cautions:
1. Connect to 12 V DC (10.8 V - 16 V) or 24 V AC (19.5 V - 28 V) class 2 power supply
only. Be sure to connect the grounding lead to the GND terminal when the power is
supplied from a 24 V AC power source.
2. To prevent fire or electric shock hazard, use a UL listed cable (VW-1, style 1007) for
the Input Terminal.
!6 Day/Night Input Terminal (DAY/NIGHT IN/GND)
This terminal is used for connecting the camera to an external day/night detecting sen-
sor.
!7 AC Inlet Socket
Plug the power cord (supplied as a standard accessory) into this socket and connect it
to an AC outlet.
!8 AC/DC Compatible Input Terminal
(DC 12 V IN/AC 24 V IN)
This terminal is for connecting the 12 V DC or 24 V AC power supply cord.
Note: Do not exceed the ratings of the voltage or current when connecting the external
device.
CONNECTIONS
A. WV-CP470 (120 V AC 60 Hz)
Plug the AC power cord (supplied as standard accessory) into the AC inlet socket and con-
nect it to a 120 V AC 60 Hz outlet.
Notes:
• Connect the power cord firmly.
• The power cord should be long enough for panning and tilting.
If the cable is too short, the power cord plug may be pulled off the camera when the
camera pans or tilts.
B. WV-CP474 (12 V DC/24 V AC)
The WV-CP474 has an AC/DC compatible input terminal. The 12 V DC or 24 V AC power
supply cord can be connected to this terminal. The camera detects the power source auto-
matically.

Alarm Connections
1. Connect an external sensor to the DAY/NIGHT terminal.
2. Connect an external device such as a buzzer or lamp to the ALARM terminal.
• The alarm output terminal is an open collector terminal with a capacity of 16 V DC, 100
mA or less.
OFF: Open contact
ON: 100 mA or less
• Color/black-and-white input terminal with a capacity of 5 V DC pull-up input, 0.2 mA or
more.
OFF: Open contact
ON: Closed contact
Notes:
• Use a relay unit if the voltage or current of the connected device exceeds the ratings.
• To validate the Day/Night function, set BW mode to EXT on the special menu.
