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
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 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. Directional Adjustment
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 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 also connects to the Camera and to
the Line Lock Board (if available).
See Figure 2 – 1 on page 7.
NOTE:
For DC input, the input voltage range is
10.5V DC to 40V DC.
The recommended input current from the power
supply should be approximately 1 Amp.
For AC input, the input voltage range is
12V AC to 28V AC.
The recommended input current from the power
supply should be approximately 1 Amp.

NOTE: Section 3 explains the camera’s
mounting procedure.
At this time, it would be advantageous to the
installer if the power input wires and the
video output wires are disconnected from
their respective connections on the VRB.
These wires can then be routed through
either the side or the bottom holes of the
housing, depending on the needs of the
installation. In this way, the wires need only
to be removed from their source one time
only.
See Figures 3-1 and 3-2 on pages 14 & 15
for further explanations.

3. MOUNTING - CAMERA BASE
The selected mounting location should not place
the camera in a situation where its environmental
specifications could be exceeded. See page 28.
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:
•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.
•Secure all cabling.
•Installations on drywall must use #8 screws
and #8 drywall nylon plugs or a superior
connection.

12
The mounting holes are configured for a single-
gang electrical box or a round ceiling electrical
box. See page 26 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.
Step 3.2 - Disconnect the Input Power wires
from the terminal block on the
Voltage Regulator Board (VRB).
Unplug the BNC section of the
Video Output cable.

13
Step 3.3 - For side wiring entry, feed the
power and video cables through the
supplied ¼ NPT nipple and connect
them as per Figure 3-1 on page 14.
Tighten the nipple into the side of
the base. Seal the wiring conduit
with silicone to prevent moisture
penetration.
Step 3.4 - For bottom wiring entry, feed the
wires through the hole in the base
and connect them as per Figure 3-2
on page 15. Close the side hole with
the supplied ¼ NPT plug.
Step 3.5 - Mount the camera base. A mounting
hole template has been provided on
page 30 for this procedure.
Step 3.6 - Seal all holes in the neoprene pad
and around the ¼ NPT plug with
silicone to prevent moisture
penetration.

14
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.
