NOTE: This equipment has been tested and found to
comply with the limits for a digital device, pursuant to part
15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. As part of its’ normal operation this
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.
2) Route the composite cable between the camera and the
power supply in steel conduit piping over the entire run of
the cable up to and including connection to a deep conduit
base fitted under the camera and a conduit fitting adaptor in
the wall of the PSU box.
3) Contact BOSCH Service Center for further advice..

DESCRIPTION
The EX27 integrated camera is an all-weather
system that includes all of the best features of a
“plug and play” camera without compromise to
CCD optics and lens quality.
Full size “Vari Focal” auto-iris lenses are
integrated as standard equipment to ensure that
a picture is received under extreme outdoor
lighting conditions.
The EX27 is rugged, compact, power protected,
weather sealed, easily installed and designed for
use in industrial applications.
A voltage regulator circuit automatically allows
for 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 EX27 is available in several models to meet
individual requirements or specific needs.

INITIAL PREPARATIONS
Determine the operating voltage at the
installation site.
All cameras have been tested prior to
shipment.
Select a suitable location that is protected from
accidental damage, tampering, and
environmental conditions exceeding the camera’s
specifications.
Caution: The selected mounting location should
not place the camera in a situation where its
environmental specifications could be exceeded.
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 a ¼” bolt
and drywall butterfly type anchor or superior
connection.
GUIDELINES
Three basic requirements must be met before
the EX27 can be installed.
1. Voltage Setting
2. Camera Wiring & Settings
3. Video Auto-Iris, CS-mount Lens
Sections 1 to 3 will guide the installer through
these settings and adjustments.

1. VOLTAGE SETTING
The camera unit is pre-connected with an electrically
isolated power board for 24V ac or 12V dc operation
with no wiring change or wiring polarity. See diagram
below for wiring details.
Note: Input voltage is 10.5VDC to 40VDC for DC input.
The AC input range is 12VAC to 28VAC.

2. LENS SETTING
The following steps show the installer how to
access the camera board and the camera lens.
Step 2.1 - Disconnect the power source to the
camera and the video signal at the
BNC connector.
Step 2.2 - Remove the four cap screws with a
3mm Allen key. See Figure 2-1 on
page 9.
Step 2.3 - Carefully slide out the rear housing
from the main enclosure. Make sure
the gasket remains with the rear
section.
See Figure 2-2 on page 10.
Step 2.4 - Make any necessary adjustments as
per Figure 3-1 on page 13.
Step 2.5 - Carefully slide the rear section into
the main enclosure and tighten the
cap screws.
