device can generate radio frequency energy and if not
installed and used in accordance with the installation
manual may cause interference to radio communications.
However, there is no guarantee that interference will not
occur on a particular installation. If the device does cause
interference to radio or television reception the user is
encouraged to try to correct the interference by one or more
of the following measures:
1) Fit Ferrite beads on all cable to and from the power
supply box, within the box walls.

DESCRIPTION
The EX7/8 Ceiling or Wall Mount Camera features one
or two CCD sensors to view “coming and going” images.
This is ideal for use in prison corridors, school hallways
and underground parking garages. The camera is
extremely durable due to its welded metal housing
shape and polycarbonate viewing windows. The EX7/8
is also weatherproof, making it perfect for outdoor use.
Cameras are available in monochrome & color.
Voltage regulator circuits automatically allow 12V dc or
24V ac operation without any wiring changes. Its’ wider
voltage range also provides protection from voltage
surge, transient spikes, and reverse voltage.
The difference between the EX7 and the EX8 is the EX7
Camera is a single sensor version and the EX8 is a dual
sensors version.

INITIAL PREPARATIONS
•Determine the operating voltage at the installation
site. The camera‘s Voltage Regulator Board
accepts both 12VDC and 24VAC input without
change to internal connections.
See Section 2, Input Power Connections.
•Determine the optimum location for the camera.
See Section 3, Mounting-Camera Housing.
•The factory default is set for ceiling mount. For
unique designation wall mount, see section 4.
•All cameras have been tested prior to shipment.
The factory default is set for ceiling mount. After
the wiring has been reconnected, it is advisable to
check the camera’s operation before installation.
GUIDELINES
Four requirements must be met before the EX7/8 can
be installed. The sections listed below will aid the
installer in setting up the camera for these requirements.

1. CAMERA HOUSING – INTERNAL MODULES,
LOCATIONS and ACCESS
Step 1.1 - Remove the four security screws holding the
welded housing to the chassis assembly. Use the
supplied Allen key.
Step 1.2 - Carefully separate the housing from the chassis
assembly, ensuring the wires are not displaced
and the camera lens is not damaged.

2. INPUT POWER / VIDEO OUTPUT CONNECTIONS
The camera unit is pre-connected with an electrically
isolated power boards for 24VAC or 12VDC operation
with no wiring change or wiring polarity. See Figure 2-1
for wiring details.
Note:
Input voltage is 10.5VDC to 40VDC for DC input.
The AC input range is 12VAC to 28VAC.
NOTE: Section 3 explains the camera’s mounting
procedure. It would be advantageous to the installer if
the power and video wires from their remote source
could be routed into the electrical box at this time. This
would make the connections to the camera easier
during the mounting process.

3. MOUNTING – CAMERA HOUSING
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. Installations on drywall must use #8 screws
and #8 drywall nylon plugs or a superior connection.
•Secure all cabling.
The mounting holes are configured for a single-gang
electrical box or a ceiling electrical box. See Section 7 for
the mounting template.

Step 3.1 Feed the camera’s power & video cables through
the foam gasket at the bottom of the camera
chassis.
Step 3.2 Connect these cables to the power & video cables
that have been routed from their remote location
into the electrical box.
Step 3.3 Mount the camera housing to the electrical box
and ceiling as shown in Figure 3-1 below.

4. CAMERA LENS – SETTINGS and ADJUSTMENTS
For optimum picture quality, the lens should be as close
as possible to the inside face of the viewing window, without
touching.
For unique designation wall mount, rotate the camera to
desire location.
Power should be applied when performing the following
adjustments.
4.1 Lens Clearance and Tilt Adjustments
Step 4.1.1 - Loosen the screws which secure the camera’s
“slide and tilt” bracket.
Step 4.1.2 -Slide the bracket to its new location, tilt the lens
and re-tighten the screws. See Figures 4-1 .

4.2 Vari Focal and “Auto-Iris” Control Adjustments
Step 4.2.1 - Loosen the lens set screws for focus/zoom
adjustments. See Figure 4-2
Step 4.2.2 - The set screw marked N ←→ ∞is used for
image focus.
Step 4.2.3 - The set screw marked T←→ W is used for
telephoto or wide-angle settings.
Step 4.2.4 - Re-tighten the set screws after focus
adjustments have been completed.
Step 4.2.5 - Locate the “Auto-Iris” adjustment controls as
shown in Figure 4-3 and adjust as per Table
A.

Use a Neutral Density filter or Infra-Red Pass filter to cover
the lens during focusing to simulate low light conditions on
scene for correct 24-hour focusing. For camera with vari-
focal lens, the camera should be focused with the lens iris
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, and all mounting screws are tight.
Step 5.1 -Gently press the camera housing in place. Ensure
the lens is not touching the inside of the viewing
window.
Step 5.2 -Tighten the housing in place with the four security
screws and the supplied Allen key.
Step 5.3 -Wipe the viewing window with a soft cloth to
remove any smudges or dirt.
Step 5.4 -Check the camera for proper operation.

Connections
Check the input power
connections at the terminal
block, ensuring no wires are
loose.
The supply range is:
12 – 28VAC OR
10.5 – 40VDC.
Measure the voltage at the
terminal block.
Determine if the wiring polarity
at the “Video Connector”
terminal block is correct.
Check BNC connector.
If still no video, connect the
camera directly to the monitor.
Check the video signal. If okay,
the problem is with the
interconnections.
If still no video, contact BOSCH
Service Center. See rear page
