2 Description

The EX36(N) Night Vision Camera has been designed with tilt
on its faceplate to allow corner mounting and t provide better
angle views in small rooms. The housing and faceplate consist
of tough materials to withstand damage in hostile environments
such as prison cells and psychiatric wards.
The smooth compact housing allows for tight installations
without exposed wiring or mounting screws, while separate
windows for the camera lens and LEDs result in a perfect
picture without light rebound.
A photocell circuit is used to provide automatic on/off infrared
operation.
The voltage regulator circuit allows for 12 VDC or 24 VAC
operation, and a range in between. This regulator also provides
protection from voltage surges, transient spikes, and reverse
voltage.

2.1 Unpacking

This electronic equipment should be unpacked and handled
with care. Check the parts list below and confirm that all items
are included. Inspect the equipment thoroughly to ensure that
nothing was damaged in transit.
Contact a Bosch Service Center if a problem is noted. Please
refer to Section 1.2 Bosch Contact Information, page 7 for
contact information in your area.

3.4 Mounting the Camera Housing

1. Select a suitable location that is protected from accidental
damage, tampering, and environmental conditions
exceeding the unit’s specifications.

CAUTION!

The selected mounting location should not place the unit in a
situation where its environmental specifications could be
exceeded.
Ensure that the location is protected from falling objects,
accidental contact with moving objects, and unintentional
interference from personnel. Follow all applicable building
codes.

2. Locate the unit so that it cannot be easily interfered with,
either intentionally or accidentally.

Bosch Security Systems, Inc. Instruction Manual F.01U.172.707 | 3.0 | 2011.02

14 en | Installation Corner-mount No-grip Camera

3. Select a mounting surface capable of supporting the
combined weight of the unit and mounting hardware to
anticipate all expected conditions of both temperature and
vibration.

4. Secure all cabling.

NOTICE!

If you are installing the camera on drywall, you must use #8
screws and #8 drywall nylon plugs or a superior connection.

5. Drill holes into the mounting surface. Depending on the
type of mounting surface (brick, wood, etc.), you may need
to pre-drill the holes for the mounting screws. Bosch
recommends that you use the housing as a drill template-­refer to Figure 3.5 for the location of the mounting holes in
the housing--to mark the location of the holes, and then
drill the holes. This way no burrs or debris will fall into the
housing.

6. Mount the housing using the supplied mounting screws.

7. Ensure that the power and video cables are not crimped or
stressed after the camera has been mounted.

3.5 Camera - Directional Adjustment

Both the camera and the LED array can be adjusted for
optimum picture quality. The camera lens can be tilted on its
axis via two adjustment screws on the mounting bracket. It can
also be moved closer to or farther from the viewing window.

1. Mount the Camera/LED Array Assembly into the housing.

2. Connect the video and power wires.

3. Check the picture for quality and directional alignment.

4. If you must adjust the camera’s viewing angle or picture
quality, remove the Camera/LED Array Assembly. Refer to
Figure 3.6.

5. Loosen both adjustment screws for tilt or horizontal
directional alignment.

6. Once optimal position is obtained, tighten the screws.

If you must adjust the power, follow these steps:

1. Ensure that the unit is “ON.”

2. Remove the rear cover for access to the LRB.

3. Cover the photocell to turn on the LEDs. (850nm LEDs will
have a slight red glow.)
– For photocell “On/Off” light-level adjustment, rotate

VR2. Clockwise is off and counter-clockwise is on.

– For IR power adjustment, rotate VR1. Clockwise is

high and counter-clockwise is low.

3.7 Lens Replacement

There is an extra 3.6 mm lens supplied with the unit and one
extra focusing hex key.
To replace the standard 2.5 mm lens with the supplied 3.6 mm
replacement, follow the steps below:

1. Open the front facia using the supplied hex key.

2. Remove the camera sub-assembly from the housing.
– For EX36MNXxxx models, use the supplied hex key to

loosen the set screw that fixes the lens to its holder.

– For EX36C7xxx models, use a Phillips screw driver to

loosen the screw that fixes the lens to its holder.

3. Thread the 2.5mm lens out. Thread the 3.6mm lens in.

4. Power up the whole sub-assembly.

5. Connect video to a monitor.

6. Adjust the back focus. Ensure that the focus is balanced on
both day and night mode. The camera can be forced to
night-mode by covering the photocell.

7. Tighten the lens.

8. Disconnect the power.

9. Mount the whole camera sub-assembly back into the
housing.

10. Adjust the camera sub-assembly mounting position so that
when you mount the sub-assembly to the housing, the lens
will not touch the window.

11. Close the front facia.

3.8 Camera Re-assembly

1. Ensure that all wires are properly connected, that all holes
are sealed against moisture penetration, and that all
mounting screws are tight.

2. Slide the square foam pad over the camera’s lens. Ensure
that the pad is as close to the faceplate viewing window as
possible and the photocell is not covered by the foam pad.
The foam pad is not symmetrical. Ensure that the LEDs are
not covered when installing the pad.

3. Re-attach the faceplate with the six tamper-resistant
screws. Tighten screws carefully, but do not overtighten.

4. Power up the camera and check its operation. Refer to
Figure 3.8 below.
