Connection of the Input Power Cable

Be careful of the following items when connecting the cables.
• Turn OFF the power supply to all components before making connections.
To video
Signal Cable
To DC 12 V or
AC 24 V

Cautions
• If thin cables are used (i.e. with a high resistance), a significant voltage drop will occur when
the unit is at its maximum power consumption. Either use a thick cable to restrict the voltage
drop at the camera side to below 10%, or place the power supply near to the camera. If
voltage drop occurs during operation, the performance will be unstable.
• Do not allow input from both a DC 12 V and AC 24 V power supply at the same time.
• When using a DC 12 V power supply, ensure that the polarities of the cable are correct.
• The AC 24 V power supply should conform to the following:
For USA : Class 2 only
For Europe : Isolated power supply only
Note
Connecting multiple VN-C205 Cameras
In a system where more than 1 VN-C205 is used, turn on the power for a VN-C205 first, followed
by setting the camera until "2-3 Setting IP Address for this Camera Using the 'VN-C205U Setup
Tool' " is completed. Upon doing so, turn on a second camera and perform setting in the same
way. Perform the same procedure for subsequent cameras.
• Default IP address setting for all VN-C205 cameras is 198.168.0.2. When the power for multiple
cameras are turned on at one time under a single LAN environment, therefore, proper access
may not be established due to IP address redundancy. Do not turn on the power of more than
1 camera at the same time.
• When IP address redundancy occurs, ensure that only one VN-C205 exists under a single
LAN environment, and wait for some time (at least 10 minutes). In some cases, the power for
all network devices under the same LAN environment may have to be turned off and on again
to enable access to VN-C205.

DC 12 V or AC 24 V Input power cable
Connect the DC 12 V or the AC 24 V power
supply to the DC 12 V/AC 24 V terminals on
the terminal board. To prevent connection er-
rors or a cable disconnection, we recommend
the use of lug plates for the connections.
The following table shows the connection dis-
tances and connection cables provided that 2-
conductor VVF cables (vinyl-insulated vinyl
sheath cables) are used.

Connection for Adjustment of the
Camera
The MONITOR terminal is used when mak-
ing various adjustments to the camera at
installation.
The power to the camera body must be ON
when adjustments are performed.
2.
Adjusting the Lens and Camera
Angle
Camera angle, zoom and focus are
adjusted.
● Horizontal rotation
(adjustable range: 120°)
Loosen the horizontal LOCK screw.
Holding the both tilt lock screws, rotate
horizontally.
Tighten the horizontal LOCK screw.
● Vertical rotation
(adjustable range: +80°, –50°)
Loosen the tilt lock screws.
Holding the rotation levers, rotate
vertically.
Tighten the tilt lock screws.
● Image inclination
(adjustable range: ±15°)
Manipulate the rotation levers to adjust
the inclination of the image.
● Adjusting the iris level
This adjustment only needs to be made
when required.( page 10)
