DESCRIPTION
The EX40N High Impact Dome Night Vision
Camera has been engineered for day/night
surveillance in hostile environments. Compact
and good looking, the camera features armour-
tough construction for protection against
vandalism or 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 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 EX40N is available in several models
designed to meet specific needs.

INITIAL PREPARATIONS
Determine the operating voltage at the
installation site. The camera has been pre-
wired for 24V ac operation before shipment.
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 EX40N 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. Camera /LED 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 EX40N camera units are 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.

3. MOUNTING - CAMERA BASE
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 13 & 14
for further explanations.

10
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.

11
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.

12
Step 3.3 - For side wiring entry, feed the
power and video cables through a
½ NPT nipple (not supplied) or an
electrical conduit and connect them
as per Figure 3-1 on page 13.
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 14. Close the side hole with
the supplied ½ NPT plug.
Step 3.5 - Mount the camera base. A mounting
hole template has been provided on
page 26 for this procedure.
Step 3.6 - Seal all holes in the neoprene pad
and around the ½ NPT plug with
silicone to prevent moisture
penetration.

13
Feed the two cables through the ½ NPT nipple
and connect them to their appropriate connector
and terminal block. Tighten the nipple and seal
the opening with silicone.
