Milesight LPR Quick Start Manual

LPR Quick Start Guide
LPR/ANPR is a technology that uses optical character recognition on images to read vehicle registration
plates. To ensure an accurate recognition result, here are some tips to help install and use Milesight LPR
cameras.

Installation Angle

To increase the accuracy of license plate recognition, the LPR cameras should be installed properly to capture
the license plates with the correct camera angle：
Proper Installation Position for Full Plate Images:
The captured image should contain full width of the vehicle.
Proper Installation Angle for Accurate Capturing:
To avoid capturing unnecessary contents in the image, the camera should be installed in a higher position
(Vertical angle is less than 30°; Horizontal angle is no more than 30°; Tile angle is less than 5°) to capture the
front part of the vehicle.

Parameter Configuration

Please configure these LPR settings and adjust for proper image quality to ensure the normal working of the
LPR function.

Set Detection Region (ROI):

You can draw the screen to set up to 4 areas to detect vehicle plates. For PTZ series cameras, you can also set
detection areas for different specific preset positions.

Choose Detect County/Region (only for LPR1):

Before using LPR function, please
select country/region to use the related detection algorithm.

Detection Settings:

[Detection Trigger]: If you choose " Always" , camera will always detect the license plate. If you choose
"Alarm input", camera will only detect the license plate when Alarm Input is being triggered.
[Confidence Level]: You can set the confidence level from 1 to 10. When the confidence level of the license
plate is higher than the set confidence level, it will push the license plate image to the logs interface.
[Repeat Plate Checktime]: Set the time interval for repeatedly reading license plates to effectively avoid
duplicate identification of parking vehicles.
