DESCRIPTION
The EX49 “No-Grip” High Impact Dome
Camera for a Vari Focal “Auto-Iris” lens 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
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.
The EX49 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 EX49 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. Lens Directional and Focus Adjustments
5. Camera Re-Assembly

1. DOME REMOVAL
The camera dome and its retaining ring must be
removed prior to mounting the camera or
adjusting the lens direction.
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 EX49 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.

3. MOUNTING - CAMERA BASE
Caution: The selected mounting location should
not place the camera in a situation where its
environmental specifications could be exceeded.
See page 30. 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.

10
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 29.
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 - Feed the camera’s power and video
cables through the foam gasket
hole.
Step 3.2 - Connect these cables to the power
and video cables that are routed
from their remote location into the
electrical box.
Step 3.3 - Mount the camera housing to the
electrical box. (Screws are not
supplied).
Refer to Figure 3-1-1, Figure 3-1-2
and Figure 3-1-3 on page 11, 12
and 13.

11
Use four (4) screws for double-gang boxes or
two (2) screws for ceiling boxes.

4. LENS: DIRECTIONAL, FOCUS, and
“AUTO-IRIS” ADJUSTMENTS
For optimum picture quality the camera lens
must be as close as possible to the dome’s
inside face, without touching.
The lens and inside dome clearance as well as
the camera’s directional adjustment can be
achieved through the use of the PTT adjustment
bracket attached to the housing base.
Refer to Figure 4-2, Figure 4-3, and Figure 4-4
on pages 17, 18, and 19 respectively.
The installer must determine whether the lens
needs to be adjusted once the camera’s viewing
angle has been finalized.
For the “Vari Focal” Auto-Iris Lens: Focal and
Zoom adjustments are shown in Figure 4-5 on
page 21.
