DESCRIPTION
The EX36N Night Vision Camera has been
designed with tilt on its faceplate to allow corner
mounting and provide better view angle 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 12V dc or
24V ac operation, and a range in between, also
providing protection from voltage surges,
transient spikes, and reverse voltage.

UNPACKING
Care should be taken when unpacking the shipped
unit. Check the parts list and confirm all items have
been located. Inspect the equipment thoroughly to
ensure nothing was damaged in transit.
Contact BOSCH Service Center if a problem is
noted, see the rear page of this booklet for contact
numbers.

for removal of faceplate mounting screws
ITEMS REQUIRED FOR INSTALLATION
(not supplied with unit)
- Mounting hardware
- Mounting tools

INITIAL PREPARATIONS
Determine the operating voltage at the
installation site.
Determine the optimum location for the
camera. Section 3, Mounting-Camera
Housing.
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.
GUIDELINES
The installation of the EX36N camera is
explained in Sections 1 to 6 listed below.
It is important that these steps are followed in
sequence:
1. Faceplate Removal
2. Input Power Connections
3. Mounting - Camera Housing
4. Camera Directional Adjustment
5. LED Directional and Power Adjustments
6. Camera Re-Assembly

1. FACEPLATE REMOVAL
The faceplate must be removed prior to the
installation process. This is necessary because
the mounting holes need to be accessed. The
lens may need to have its directional angle
changed.
Refer to Figure 1-1 on page 5.
Step 1.1 - Place the camera housing on a flat
surface.
Step 1.2 - Use the supplied “security” Allen
wrench to remove the six screws
holding the faceplate into the
Step 1.3 - Remove the square foam cushion
attached to the camera lens.
Step 1.4 - Ensure the polycarbonate windows

3. MOUNTING - CAMERA HOUSING
Select a suitable location that is protected from
accidental damage, tampering, and
environmental conditions exceeding the camera’s
specifications.
Caution:
not place the camera in a situation where its
environmental specifications could be exceeded.
See page 24
Caution:
protected from falling objects, accidental contact
with moving objects, and unintentional
interference from personnel. Follow all applicable
building codes.
The selected mounting location should
Ensure the selected location is
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
9
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.
The camera’s mounting holes are located on the
left and right side of the housing.
Refer to Figure 3-1 on page 11.
Depending on the type of mounting surface
(brick, wood, etc.), it may be necessary to predrill these holes for the mounting screws. It is
recommended that these holes be marked using
the housing as a drill template and then drilled
separately. This way no burrs or debris will fall
into the housing.
Ensure the power and video cables are not
crimped or stressed after the camera has been
mounted.

4. 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 or farther away from
the viewing window.
Mount the Camera/LED Array Assembly into the
housing. Connect the video and power wires.
Check the picture for quality and directional
alignment.
Remove the Camera/LED Array Assembly if an
adjustment is required to the camera’s viewing
angle or picture quality.
Refer to Figure 4-1 on page 13.
12
Loosen both adjustment screws for tilt or
horizontal directional alignment. This action may
require trial-and-error attempts to obtain perfect
picture alignment.
FIGURE 4 – 1

5. LED DIRECTIONAL AND POWER
ADJUSTMENTS
If the LEDs need to be adjusted for beam
spread, the Camera/LED Array Assembly does
not need to be removed from the housing. The
adjustment can be done by hand.
The EX3xN can be powered while making
adjustments, but make sure the power cable is
not pinched or chafed during this procedure.
Cover or adjust the photo-cell to turn the LEDs
“ON” (850nm LEDs will have a slight red glow
while 940nm LEDs are covert). Adjust the LED
power if they are too bright.
Refer to Figure 5-1 on page 15.
In some cases it may be necessary to bend the
LEDs slightly for better beam spread. Do not use
your fingers for this function. Use a flat wooden
object and gently push the outside row of LEDs
inwards or outwards. The camera should be
“ON” while this adjustment is in progress.
14
LED ARRAY - POWER ADJUSTMENTS
If adjustment is needed, remove the rear cover for
access to the LRB. The EX36N needs to be
powered-up while making the LED power
adjustments. Cover the photocell to turn the LEDs
“ON” (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.

6. CAMERA RE-ASSEMBLY
Make sure all wires are properly connected, all
holes are sealed against moisture penetration,
and all mounting screws are tight.
Step 6.1 - Slide the square foam pad over the
camera’s lens. Make sure 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. Make sure the LEDs
are not covered when installing the
pad.
Step 6.2 - Re-attach the faceplate with the six
tamper resistant screws. Tighten
carefully but do not over-tighten.
Step 6.3 - Power-up the camera and check its
operation.
Refer to Figure 6-1 on page 17.

Fuse Blows
Don’t know if LEDS are
“ON”
LEDs are not “ON”
PROBLEM
POSSIBLE SOLUTION
- Check fuse rating.
- Check for shorting between
the enclosure and the
input power.
850nm LEDs will have a
faint red glow when “ON”.
940nm LEDs are covert.
Aim the LEDs directly at an
IR sensitive camera to see
the lights or wait for the
LEDs to warm up (two
minutes).
- Cover the photo sensor to
activate power to the LEDs
( up to 30 seconds delay
for activation ).
- Adjust the photocell’s
variable resistor towards
the “ON” position.
- Adjust power to the LEDs.
- Measure input voltage
>12VDC
21
PROBLEM
LEDs are not turning
“OFF” when sufficient
ambient light is present
POSSIBLE SOLUTION
- Make sure the photo
sensor is not covered or
hidden behind any object.
- Adjust the photocell’s
variable resistor towards
the “OFF” position.
The LEDS will stay “ON”
or “OFF” if the adjustments
are at full turn.
