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.

DESCRIPTION

The REG-L1 license plate capture camera unit consists of
one IR-sensitive monochrome camera and one integrated
panel of Infrared LEDs. The license plate capture camera
produces optimum license plate images during day and night
settings in all-weather conditions. The camera has optical
filtering technology that help block out unwanted ambient light
such as headlamps or sunlight, thus ensuring no bloomed-out
or washed-out images of the license plates.

The REG-L1 camera you have purchased is designed and
configured to capture images of license plates under a wide
range of ambient light to weather conditions.

The all-weather housing with a covert acrylic window contains
all the electronics. Low voltage operation, low power
consumption, LED illuminator, and solid-state CCD
technology make this camera very reliable and efficient.
A voltage regulator circuit allows for DC or AC operation
between 12 and 24 VAC/VDC. It also provides protection
from voltage surges, transient spikes, and reversed 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.

PARTS LIST (items supplied with unit)

- Installation Instructions booklet

ITEMS REQUIRED FOR INSTALLATION (not

supplied with units)

• Mounting hardware

• Mounting tools

• Proper Power Supply

- 2 -

INITIAL PREPARATIONS

• Determine the operating voltage at the

installation site. The camera‘s Voltage Regulator
Board accepts both 12-24VDC and VAC input
without change to internal connections.

See Section 2, Input Power/Video Output

Connections.

• Determine the optimum location for the camera.

See Section 3, Mounting Specification.

• 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.

Note: To ensure the camera is working, you must

use a retro reflective license plate.

GUIDELINES

The installation of the REG-L1 camera is explained in
Sections 1 to 3.
It is important that these steps are followed and practice
proper installation procedures with proper safety
equipment.

3. MOUNTING SPECIFICATION

Caution: Install with appropriate screws to suit
mounting surface. Select a suitable location that is
protected from accidental damage, tampering and
environmental conditions exceeding the camera’s
specifications.
See page 13.

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.

• Secure all cabling.

The REG-L1 units have a recommended operation range
with specified optimal capture distance for each model as
shown below. Any number plate recognition installation
should also aim to control the traffic through a lane.

Model Range, ‘R’ Optimal

REG-L1-816 12 – 22 ft | 3.7 – 6.7 m 16 ft | 4.9 m
REG-L1-825 20 – 34 ft | 6.1 – 10.4 m 25 ft | 7.6 m
REG-L1-835 27 ft – 48 ft | 8.2 – 14.6 m 35 ft | 10.7 m
REG-L1-850 40 ft – 68 ft | 12.2 – 20.7 m 50 ft | 15.2 m

REG-L1-875 55 ft – 80 ft | 16.8 – 24.4 m 75 ft | 22.9 m
ranges (for use with number plates of size 12in x 6in (305mm x
152mm) – common in North America.

Model Range, ‘R’ Optimal

REG-L1-812 10 – 20 ft | 3 – 6 m 16 ft | 5 m
REG-L1-816 16 – 26 ft | 5 – 8 m 23 ft | 7 m
REG-L1-825 23 – 40 ft | 7 – 12 m 33 ft |10 m
REG-L1-835 34 – 60 ft | 11 – 18 m 50 ft | 15 m
REG-L1-850 56 – 82 ft | 17 – 25 m 72 ft | 22 m

REG-L1-875 72 – 100 ft | 22 – 30 m 92 ft | 28 m
ranges for use with number plates of size 20.6in x 4.4in (524mm
x 112mm) – common in the UK.

Distance*

Figure 3 REG-L1 Range Chart

* Optimal distance calculated to allow license
plates of 120 pixels wide. Most DVR application

- 7 -

can provide readable plates larger than 80
pixels depending on level of image compression
set on DVR.

The maximum angle of the unit to the car is 40º.
This is both horizontally and vertically. This
limits the amount of skew of the letters on the
number plate. If the letters are skewed too much
they will start to become unrecognizable and will
reduce automatic software recognition rates.

If the maximum range is exceeded the letters will
become smaller and be more difficult to read. At the
max range the width of the number plate covers
approximately 12% of the width of the screen.

Note: The ‘R’, Range is the distance from the
camera to the license plate. Working below max
range gives larger number plates and hence
more accurate recognition but less lane area to
be covered. If too close the license plate could
disappear from the Field-of-View, especially for
side-mounted plates.
