DESCRIPTION

The EX49 “No-Grip” High Impact Dome
Camera for a Vari Focal “Auto-Iri s” len s 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) mo unting 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 Direction al an d 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 Accordan ce 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 approxim ately 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 approxim ately 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 un der 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.

9

The mounting holes are configured for a single -ga ng
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 coul d be routed
into the electrical box at this time.

Step 3.1 - Feed the camera’ s po wer 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.

10

Use four (4) screws for double-gang b oxes 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 a s 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 th e lens
needs to be adjusted once the came ra’s viewing
angle has been finalized.

For the “Vari Focal” Auto-Iris Lens: Fo cal and
Zoom adjustments are shown in Figure 4-5 on
page 21.

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.

Vari Focal Lens Adjustments

• Loosen the lens set screws for focus/zoom

adjustments.

• The setscrew marked N ←→ ∞ is used for

image focus.

• The setscrew marked T←→ W is used for

telephoto or wide-angle settings.

• Re-tighten the setscrews after focus

adjustments have been completed.

22

Use a Neutral Density filter or Infra-Red Pass filter to cover

the lens during focusing to simulate low light conditio ns on
scene for correct 24-hour focusing. For camera with vari­focal lens, the camera should be focused with the lens ir is
fully opened to simulate the worst possible depth of field.
Using a Neutral Density filter or Infra-Red Pass filter will
ensure the iris is fully open for correct setup and
adjustment.

Note that statement above is applicable only for Day/Night

or IR version cameras.

5. CAMERA RE-ASSEMBLY

Make sure all wires are properly connected and
tightened into the terminal blocks, all holes are
sealed against moisture penetration, an d all
mounting screws are tight.

Step 5.1 - Check that the large “O” ri ng gasket

in the camera base has not been

dislodged or distorted.

Step 5.2 - Gently press the camera dome in

place. Move the retaining ring over

the dome.

Step 5.3 - Use the protruding set-screws in the

retaining ring to carefully rotate the

ring clockwise until it is slightly snug,

but not so tight that the ring cannot

rotate further.
Step 5.4 - Press firmly on the dome and rotate

the retaining ring until one of the

set-screws aligns with the

adhesive dot on the side of the

dome. Tighten all set-screws with

the supplied Allen key. Refer to

Figure 5-1 on page 25.
