Mounting the Lens

Note:Before you mount the lens, loosen the screw on the side of the camera, and rotate the
ring clockwise until it stops.
If the ring is not at the end, the inner glass or CCD image sensor may be damaged.
1. Attach the supplied C-mount
adapter when using a C-mount
lens.
2. Jump to step 3 if the lens has focus
adjusting mechanism. Loosen the
flange-back screw, and rotate the
adjusting ring down until it stops on
the side of the camera.
3. Mount the lens.
4. Connect the lens cable to the auto
iris connector on the side of the camera.

Flange-back Adjustment

The adjustment is required only when a lens without focus-adjusting mechanism is mounted,
or when a lens with adjusting mechanism is mounted and focus that is more accurate is
needed.
1. Loosen the flange-back fixing screw on the flange-back adjusting ring.
2. Turn the flange-back adjusting ring to obtain a focused point while watching the monitor
screen.
3. Tighten the flange-back fixing screw on the flange-back adjusting ring.
Caution: Tightening the screw by force will cause damage to the screw or deviation of
focus.
Note: The object may be out of focus when using a source of near-infrared light than
using the visible light.

Caution for Mounting the Lens

Follow the indication shown in the figure for the protrusion between a lens and the camera
body. This camera wears mount for use with the CS-mount lens at the factory shipment.
Use the supplied C-mount adapter when using the C-mount lens.
The lens less than 450 g(0.99 lbs) can be mounted on the camera. If the lens is heavier,
both the lens and camera should be
secured by the supporter.
C-mount: Less than 13 mm (1/2”)
CS-mount: Less than 8 mm (5/16”)
MOUNTING LENS/FOCUS ADJUSTMENT
•Mounting from the Top
Remove the mount adapter from the bottom of the camera by removing the two fixing
screws. Attach the mount adapter to the top as shown in the figure, then mount the
camera on the mounting bracket.
Cation:
Be sure to use two original fixing
screws for the mount adapter.
Longer screws may damage the inner
components. Or shorter screws may
cause the camera drop.

Installation of Auto Iris Lens Connector

Install the lens connector (YFE4191J100) when using a video drive ALC lens.
(1) Cut the iris control cable at the edge of the lens connector to remove the existing lens
connector and then remove the outer cable cover as shown in the figure below.
The pin assignment of the lens connector is as follows:
Pin 1: Power source; +9 V DC, 50 mA max.
Pin 2: Not used
Pin 3: Video signal; 0.7 V[p-p]/40 kΩ
Pin 4: Shield, ground
(2) Solder the lens cable to the pins of the
supplied connector.

■Connections
Precaution:
The following connections should be made by qualified service personnel or system
installers in accordance with NEC 725-51.
Note: For the WV-CP474E Colour CCTV Camera, do not use a transformer larger than
10VA.

• Power supply connection

Recommended wire gauge sizes for 24 V AC line.
Cautions:
1. CONNECT THIS TO 24 V AC CLASS 2 POWER SUPPLY ONLY. Be sure to connect
the grounding lead to the GND terminal.
2. To prevent fire or electric shock hazard, use a UL listed cable (VW-1, style 1007) for
the Input Terminal.
3. The connections should comply with National Electrical Code (NEC).
CONNECTIONS

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.

Cautions:
1. Shrinking the cable-entry seal is a one-time procedure. Do not shrink the cable-entry
seal until it has been ascertained that the unit is functioning.
2. CONNECT THIS TO 24 V AC CLASS 2 POWER SUPPLY ONLY. Be sure to connect
the grounding lead to the GND terminal.
3. To prevent fire or electric shock hazard, use a UL listed cable (VW-1, style 1007) for
the Input Terminal.
4. The connections should comply with National electrical Code (NEC).
