DESCRIPTION
The EX49N “No-Grip” High Impact Dome
Night Vision Camera has been engineered for
surveillance in hostile environments. Compact
and good looking, the camera features a smooth
“no-grip” housing for protection against theft and
vandalism.
An aluminum housing, CNC-machined from a
solid billet, with an impact resistant
polycarbonate dome and locking retaining ring,
make it extremely rugged and weather-tight.
For flexibility, the CCD Camera/LED Array can
be fully rotated using a unique “Pan-Tilt-Twist”
(PTT) mounting bracket.
A voltage regulator circuit allows for 12V DC or
24V AC operation, and a range in between, also
providing protection from voltage surge,
transient spikes, and reverse voltage.
The EX49N is available in several models
designed to meet specific needs.

INITIAL PREPARATIONS
Determine the operating voltage at the
installation site. The camera‘s Voltage
Regulator Board accepts either +12V DC or
24V AC input.
See Section 2, Input Power Connections.
Determine the optimum location for the
camera. Section 3, Mounting-Camera Base.
All cameras have been tested prior to
shipment. After the wiring has been
reconnected, it is advisable to check the
camera’s operation before installation.
ESD protection – Cameras and circuit boards
are sensitive electronic components. It is
recommended to wear a ground strap to
ground any static charge. (Alternative: touch a
grounded metal plate for at least a minute
before proceeding with any disassembly)
GUIDELINES
The installation of the EX49N camera is explained
in Sections 1 to 5 listed below. It is important that
these steps are followed in sequence:
1. Dome Removal
2. Input Power Connections
3. Mounting – Camera Base
4. Adjustments
5. Camera Re-Assembly

1. DOME REMOVAL
The camera’s dome and its retaining ring must
be removed prior to mounting the camera or
performing any wiring disconnections and re-
connections. The set-screws in the retaining ring
are not tightened in the factory and protrude by
1/8" (3mm) in order for the ring to be rotated.
Refer to Figure 1 - 1 on page 5.
Step 1.1 - Place the camera on a flat surface.
Step 1.2 - Press firmly on the dome with one
hand and rotate the retaining ring in
a counter-clockwise direction with
the other hand. Push against the
protruding set-screws with a finger
to rotate the ring. Do not use a
screwdriver or other metal device.
Step 1.3 - Remove the dome and the retaining
ring. Set them aside.

2. INPUT POWER CONNECTIONS
Attention: External Video Cable Systems Must
Be Properly Grounded In Accordance With The
National Electrical Code, ANSI/NFPA 70.
The EX49N Camera Unit is pre-connected with
an electrically isolated power board (VRB) for
24V AC or 12V DC operation, with no change to
the polarity of the wires.
The VRB connects to the Camera and LED
Array Power Board.
See Figure 2 – 1 on page 7 and Figure 2 – 2 on
page 8
NOTE:
For DC input, the input voltage range is
10.8V DC to 26.4V DC.
The recommended input current from the power
supply should be approximately 1 Amp.
For AC input, the input voltage range is
10.8V AC to 26.4V AC.
The recommended input current from the power
supply should be approximately 1 Amp.

3. MOUNTING - CAMERA BASE
IMPORTANT MOUNTING INSTRUCTIONS
WARNING: THIS APPARATUS MUST BE SECURELY
ATTACHED TO THE WALL OR CEILING IN ACCORDANCE
WITH INSTALLATION INSTRUCTIONS. FAILURE TO FOLLOW
INSTALLATION INSTRUCTIONS MAY RESULT IN INJURY
The selected mounting location should not place the
camera in a situation where its environmental
specifications could be exceeded. See page 25.
Caution: Ensure the selected location is protected from
falling objects, accidental contact with moving objects, and
unintentional interference from personnel. Follow all
applicable building codes.
The following installation guidelines must be
followed:
Installation should only be performed by skilled
personnel.
Locate the camera such that it cannot be easily
interfered with, either intentionally or
accidentally.
Select a mounting surface capable of supporting
the combined weight of the camera and
mounting hardware under all expected
conditions of vibration and temperature or
equivalent.

10
Secure all cabling.
Camera has been evaluated for wall/ceiling
mounting using #8 1¼” long, 12 TPI, wood
screws with Robertson heads secured into a 2x4
stud under ½” drywall
Camera has not been evaluated for safety
requirements using other mounting kits.
The mounting holes are configured for a single-gang
electrical box or a round ceiling electrical box. The
camera base can also be mounted to any flat
surface. See the template on page 23.
It would be advantageous if the power and video
wires from the remote source could be routed into
the electrical box at this time.
Step 3.1 - Connect the cables coming out of the
camera to the power and video cables that
are routed from their remote location into
the electrical box or equivalent.
Step 3.2 - Mount the camera housing to the electrical
box or surface. (Screws are not supplied).
Refer to Figure 3-1 on page 11.

Note:
Gasket Back Cover - Some products have a paper
backing on the gasket. Please remove it before
installation.
Mounting - It is recommended that the camera be
mounted to a flat non-porous surface for best
results. The mounting holes and the area around
the mounting screws should be sealed with silicone
to prevent water or moisture from entering into the
unit.
Conduits and Connectors - The conduits and
connectors connecting to the housing should be
sealed with silicone to prevent water and moisture
from entering into the unit.

4. ADJUSTMENTS
For optimum picture quality the camera lens
must be as close as possible to the dome’s
inside face, without touching. However, the foam
ring around the lens should be adjusted to seal
against the dome, minimizing any side light
interference, but without obstructing the field of
view.
The lens dome clearance and camera viewing
angles can be achieved through a combination
of adjustments available on the PTT bracket.
If the lens touches the dome, loosen the side
adjustment knobs and slide the Camera/LED
Array assembly away from the dome. See
Figure 4-2 on page 15. The Camera and PTT
bracket can also be rotated horizontally, see
Figure 4-3 on page 16. The camera picture can
be adjusted by twisting the PTT disc, see Figure
4-4 on page 17. The LED Array brightness has
been set at the factory before shipment. For
photocell sensitivity adjustments see Figure 2-2
on page 8.

Note: If light reflects from side walls or other adjacent
surface, some bright spots or halo may appear on the image.
Move lens away from the reflection surfaces in order to avoid
back reflection.
