DESCRIPTION
The EX40 Hi-Impact Dome Camera has been
engineered for surveillance in hostile
environments. Compact and good looking, the
camera features armour-tough construction for
protection against vandalism or against
accidental damage.
An aluminum housing, CNC-machined from a
billet, with an impact resistant polycarbonate
dome and locking retaining ring, make it
extremely rugged and weather-tight.
For viewing adjustment, the CCD Camera/Lens
Assembly 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.

INITIAL PREPARATIONS
Determine the operating voltage at the installation
site. The camera’s Voltage Regulator Board can
accept a 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 EX40 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

4
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 setscrews 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 setscrews 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 EX40 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.
See Figure 2 – 1 on page 7.
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

9
expected conditions of vibration and
temperature or equivalent.
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. See page 25 for the mounting hole
diagram. The housing can also be mounted to
any flat surface.
Step 3.1 - Once the mounting location has
been selected, determine if the
video and the power input wires
should enter the housing through
either the side or the bottom. For
ease of re-assembly, this step
should be performed in conjunction
with Section 2, Input Power
Connections.

10
Step 3.2 - For side wiring entry, feed the
power and video cables through a
½” NPT electrical conduit and
connect them as per Figure 3-1 on
page 11. Tighten the conduit into
the side of the base. Seal the wiring
conduit with silicone to prevent
moisture penetration.
Step 3.3 - For bottom wiring entry, feed the
wires through the hole in the base
and connect them as per Figure 3-2
on page 12. Close the side hole with
the supplied ½” NPT plug.
Step 3.4 - Mount the camera base. A mounting
hole template has been provided on
page 25 for this procedure.
Step 3.5 - Seal all holes in the neoprene pad
and around the ½” NPT plug with
silicone to prevent moisture
penetration.

11
Feed all cables through the electrical conduit
and connect them as shown.
NOTE: Make sure the BNC connector and all
other wires are tucked into an area of the
camera base where no damage can occur to
any electrical parts.

other wires are tucked into an area of the
camera base where no damage can occur to
any electrical parts.

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/lens
assembly away from the dome, see Figure 4-2
on page 16. The camera and PTT bracket can
also be rotated horizontally, see Figure 4-3 on
page 17. The camera alignment can be adjusted
by twisting the PTT disc, see Figure 4-4 on
page 18. Zoom and Focus adjustments can be
made as shown in Figure 4-5 on page 19.
Refer to Figure 4-1 on page 15 for an overview
of directional viewing.
