Initial Setup
Before installing the V25 Camera, you must first:
• Disassemble the camera.
• Set up the camera for mounting on a wall or a ceiling.
Disassembling the Camera
To disassemble the camera:
1. Use the security hex key provided to remove the three #6-32 x 3/8 in. machine
screws securing the V25 front plate and dome to the base (see Camera
Components). Set aside the screws.
2. Use a Phillips screwdriver to remove the two #6-32 x 1/4 in. machine screws
that attach the camera gimbal to the gimbal support bracket.
Do not remove the camera carrier from the gimbal at this time. Also, do not
disconnect the wires from the camera.

Wall Mount Setup
When the V25 Camera is mounted on a wall, the camera carrier can be adjusted to
pan and tilt.
Once you have disassembled the camera, prepare the camera for mounting on a
wall:
1. Use a pair of side-cutters to remove the perforated square in the gimbal
support bracket (see Wall Mount Setup). Discard this square. This allows full
motion of the camera gimbal.
2. Use a Phillips screwdriver and two #6-32 x 1/4 in. machine screws to attach
the camera gimbal and camera carrier to the modified gimbal support bracket.
The V25 Camera is now set up for mounting on the wall. Proceed to Installation on
page 6.

Ceiling Mount Setup
When the V25 Camera is mounted on the ceiling, the camera carrier can be
adjusted to rotate and tilt.
Once you have disassembled the camera, prepare the camera for mounting on a
ceiling:
1. Remove both arms from the gimbal support bracket by holding the end of the
arm and bending it back and forth until it breaks off (see Figure 3). Do not
remove the center square from the gimbal support bracket.
2. Use a Phillips screwdriver to remove the two #6-32 x 1/4 in. machine screws
that attach the camera carrier to the gimbal.
3. Use side-cutters to remove the two perforated arms of the gimbal.
4. Attach the gimbal to the gimbal support bracket (see Figure 3) using one #6-32
x 3/8 in. machine screw and a #6 nylon washer (provided). Tighten the screw.
Caution The nylon washer must be mounted between the gimbal
and the gimbal support bracket to allow the gimbal to
rotate clockwise without binding.
5. Use two #6-32 x 1/4 in. machine screws to attach the camera carrier to the
gimbal.
Caution Line-lock cameras have an electrically isolated camera
carrier to prevent ground loop problems. Ensure the nylon
bushings and insulating washers are installed as shown in
Figure 3.
The V25 Camera is now ready for mounting on a ceiling. Proceed to Installation on
page 6.

Installation
The V25 Camera is designed to be flush mounted on a panel or in a standard deep
double-gang electrical box. The camera can be located indoors or outdoors, on a
wall or ceiling, in accordance with the current Electrical Code or any national wiring
rules that apply.
Follow the Initial Setup procedure before installing the V25 Camera.
Mounting the Camera on a Wall or Ceiling
To mount the V25 Camera on a wall or ceiling panel:
1. Mark and drill out mounting holes in the wall or ceiling panel (see Figure 4),
using the mounting template shown on page 21.
2. Insert the camera base into the mounting hole.
3. Secure the camera to the mounting panel using four #6-32 self-tapping screws
(not provided).
Note An optional V25 Backing Plate Kit is available to mount the V25
Camera in a removable ceiling panel as shown in Figure 4. Please
contact Silent Witness Sales for more information.

This camera is polarity independent for AC operation
(see Adjusting the Line Lock (Vertical Phase) for 24 VAC
Operation).
To ensure the vertical alignment is the same for all cameras,
make all power connections the same phase.

2. Install a male BNC connector on the video cable coming from the video
monitor or CCTV system.
3. Connect the video cable to the female BNC connector and cable coming from
the base of the V25 Camera.
4. Connect the AC or DC power wires to the red and black wires coming from
the base of the V25 Camera, as shown in Figure 5.
WARNING! The use of CSA Certified/UL Listed Class 2
power adapters is required to ensure
compliance with electrical safety standards.
Caution For outdoor installations, or any installation where water
may be a problem, ensure that all electrical connections are
covered to prevent short circuits or contamination.
Aiming and Focusing
To aim the V25 Camera:
1. Turn on the camera power and monitor the video signal. Adjust the camera
carrier to the desired view.
Note The TOP (of picture) label must be on the top of the lens mount
to ensure the video image is upright.
2. If necessary, turn the lens to adjust the focus (see Figure 6).
Cameras with a 12 mm lens may need the lens rotated approximately 1/4 of a
turn counterclockwise to allow for the magnification properties of the dome.
Hold the front plate and dome in position to check the focus.
3. Hold the front plate and dome in place to ensure that it does not interfere with
the camera or block the camera view. If the enclosure cover does interfere
with the camera, slide the camera support bracket away from the camera lens
(toward the terminal board).
If vibration is a significant factor, use Loctite™ Serviceable Threadlocker (or
equivalent) to secure all camera adjustments.

Changing the Quick Change Lens
Some V25 Cameras have a quick change lens mount, designed to provide a fast and
easy way to change the camera lens. To change the quick change lens:
1. Remove the quick change lens:
a. Turn the lens holder 45° counterclockwise (see Figure 6).
b. Pull the lens holder out of the lens mount.
2. Install a new quick change lens:
a. Insert the lens holder into the lens mount. Align the locking lugs on the
lens holder with the grooves in the quick change lens mount (see Figure 6).
b. Turn the lens holder 45°clockwise to lock the lens holder in the lens
mount.
c. If necessary, turn the lens to adjust the focus.
Note Lenses are pre-focused at the factory but may require a final
adjustment after installation.

Adjusting the Line Lock (Vertical Phase) for 24 VAC
Operation
In multiple camera installations, wire all cameras to the same phase. This will ensure
that the vertical phase of all cameras are aligned. Phase adjustment may be necessary
to prevent picture roll when switching between cameras.
Note If the phase cannot be adjusted to prevent picture roll, reverse
the power polarity.
To adjust the vertical phase:
While switching between the two cameras, turn the Line-lock adjustment screw
(see Figure 7) on one camera until there is no vertical roll.
Adjusting the Backlight Compensation
The backlight compensation (BLC) adjusts the electronic shutter speed of the
camera based on the light levels in specific areas of the scene. This adjustment
provides better image quality for scenes that are unevenly lit.
To adjust the BLC, set the BLC switch to ON (see Figure 8). Center window
weighted.
Installing the Front Plate and Dome
Secure the front plate and dome to the base with the three #6-32 5/8 in. security
machine screws, using the hex key provided.
Routine Maintenance
Use regular liquid cleaners to remove most dirt and grime from the dome.
Caution Do not use harsh or abrasive cleaners which can scratch
the polycarbonate dome and reduce visibility of the
camera.
If the camera view is obstructed by scratches, remove the front plate and rotate it
120° to find an unscratched part of the dome.

15
Replacing the Dome
If the polycarbonate dome is damaged or scratched beyond use, contact your
distributor or salesperson to order a V25 Dome Replacement Kit.
To replace the V25 dome:
1. Use the security hex key (provided) to remove the three #6-32 5/8 in. machine
screws securing the V25 plate and dome to the base (see Figure 9). Put aside.
2. Use a Phillips screwdriver to remove the three #6-32 1/4 in. machine screws
that attach the dome retainer plate to the front plate.
3. Remove the damaged dome and replace it with the new dome and gasket. The
gasket should be between the dome and the V25 base (see Figure 9).
4. Use a Phillips screwdriver to attach the dome retainer plate to the V25 front
plate with the three #6-32 1/4 in. machine screws you removed in step 2.
5. Use the security hex key to replace the three #6-32 x 3/8 in. machine screws
to attach the front plate and dome to the base.
