Introduction
This guide provides instructions on how to install a License Plate Recognition (LPR) system using the Avigilon HD
LPR Capture Kit.
For information on how to select an appropriate LPR camera model and mounting location, see Site Design on
the next page.
For information on how to install and position the HD LPR Capture Kit, see Installation on page11
For information on how to use the License Plate Recognition feature in the AvigilonControl Center™ (ACC), see

Introduction 6
Site Design
This section will help you select an appropriate LPR camera model, number of NVR servers, and mounting
location based on your video surveillance requirements. It is important to read this section before installing the
HD LPR Capture Kit to ensure LPR accuracy.
LPR Camera Selection
The target distance is the physical distance between the LPR camera and the license plate detection area.
Each HD LPR Capture Kit model is calibrated for a specific target distance. Refer to the table below to select the
appropriate kit:
Target Distance (ft [m]) Single Lane Dual Lanes
35 [11] 1L-HD-LP-35 N/A
50 [15] 1L-HD-LP-50 N/A
75 [23] 1L-HD-LP-75 N/A
100 [30] 1L-HD-LP-100 N/A
40 [12] N/A 2L-HD-LP-40
Required Number of Servers
The Avigilon HD LPR Capture Kit is designed to cover a single traffic lane of 10 ft (3m) or two adjacent traffic
lanes. The maximum number of lanes that can be monitored on a single server depends on the target vehicle
speed and the mounting height.
Speed (mph [km/h])
0-20 [0-32] 4 2
20-30 [32-50] 2 1
30-40 [50-65] 1 1
40-60 [65-100] 1 Not recommended
NOTE: The Avigilon LPR software should only be run on Avigilon HD NVR servers or machines with similar
specifications. For HDNVR servers, it is recommended that you use an additional processor to supplement the
processing requirements of the LPR.
Maximum number of lanes per NVR
(Recommended Overhead)
System Requirements
The Avigilon LPR software can only run on the following operating systems. Make sure the servers are using one
of these operating systems before you install the LPR software.

Selecting a Mounting Location
You must select a mounting location before you can install the HD LPR Capture Kit. It is important to mount the kit
in an appropriate location to optimize the LPR accuracy.
The kit can be mounted in the overhead or roadside position. The LPR camera can recognize vehicles traveling
at up to 100 km/h (60 mph) when mounted in the recommended overhead mounting height, but the maximum
detectable speed decreases to 65 km/h (40 mph) when mounted in the maximum overhead mounting height or
when mounted in the roadside position.
Overhead Mounting
In overhead mounting, the HD LPR Capture Kit is mounted directly above the vehicle path. Refer to the following
tables for recommended and maximum mounting heights for each HD LPR Capture Kit model and their
corresponding horizontal distances to the license plate detection area.
Overhead Recommended Mounting Height:
HD LPR Capture Kit Target Distance (ft [m])
1L-HD-LP-35 35 [11] 9 – 12 [2.8 – 3.6] 33 [10]
1L-HD-LP-50 50 [15] 13 – 17 [4.0– 5.2] 48 [14.5]
1L-HD-LP-75 75 [23] 19 – 26 [5.9 – 7.8] 72 [22]
1L-HD-LP-100 100 [30] 26 – 34 [7.9 – 10] 95 [29]
2L-HD-LP-40 40 [12] 10 – 14 [3.1 – 4.2] 38 [11.5]
Overhead Maximum Mounting Height:
HD LPR Capture Kit Target Distance (ft [m])
1L-HD-LP-35 35 [11] 18 [5.5] 30 [9.2]
1L-HD-LP-50 50 [15] 25 [7.5] 43 [13]
1L-HD-LP-75 75 [23] 38 [11] 65 [20]
1L-HD-LP-100 100 [30] 50 [15] 87 [26]

Roadside Mounting
If overhead mounting is not possible, then use roadside mounting. In roadside mounting, the HD LPR Capture Kit
is often pole-mounted on the side of the road. Refer to the following table for the maximum mounting height and
offset distance for each HD LPR Capture Kit model. Select the shortest target distance that results in a practical
mounting location.
NOTE: The dual lane kit (2L-HD-LP-40) should not be mounted in the roadside position.
