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)

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

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.
