I. What is ANPR

ANPR(Automatic Number Plate Recognition) is a technology that uses optical character recognition on images to read vehicle registration plates. For Milesight, the ANPR algorithm is embedded in cameras, which allows the cameras to recognize, capture and upload license plate images all alone and intelligently.

Notes:

Installation Angle Considerations


To increase the accuracy of license plate recognition, be sure to install the LPR cameras properly to capture the license plates with the correct image size, lighting conditions and camera angle. The following highlights is the precautions of installation angle

A: Installing the camera in front of the vehicle (Recommended):

The captured image should be filled with a full width of the vehicle.

B: Installing the camera slightly to the side:

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.

IV. How to set ANPR with Milesight Network Cameras

1. Settings

Step1: Go to "Advanced Settings" → "LPR" → "Settings" after log in the web. Check the checkbox “Enable License Plate Recognition”, and you can draw the screen to select the areas interested. There will be shown in the blue box as below.

ANPR

[License]: A license will be automatically assigned to each device.

[License Status]: This column is used to display the status of the license, "Valid" or "Invalid".

ANPR

[Processing Resolution]: Default resolution selected is 1280*720. You can choose different resolution according to the network environment.

ANPR
ANPR

[Set LPR Detection Region]: You can set up to 4 ROI areas by drawing the screen. If you choose Normal Mode, it supports configuring the LPR detection regions for the current area. If you choose Advanced Mode(Only for PTZ series), it supports configuring different LPR detection regions for different PTZ presets(Only support Preset 1~4 so far).

Note:

• The optimal interval of Milesight LPR cameras to recognize license plates width is within 100-200 PX.

• For better performance, please choose the appropriate resolution in advance.

ANPR

[LPR Night Mode]: Achieve the best effect of LPR night recognition by adjusting different parameter levels. You can also schedule the Start Time and End Time, and adjusting the level according to the environment.

Step2: Schedule Settings. You can draw the schedule by clicking [Edit] button. And then click [Save] or [Reset] after finishing the setting.

ANPR
ANPR

Step3: Detection Settings and LPR Message Post Settings.

ANPR

[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.

ANPR

[License Plate Serial Format]: Formulate identification rules and automatically filter wrong license plate information to achieve more intelligent and accurate license plate recognition.

[Feature Identification]: Check Region, Direction, ROI_ID or All to enable Features Identification, it will display the corresponding information on the logs interface.

Note: Region detection only supports DACH region.

[LPR Message Post Settings]: Check the checkbox to enable LPR Message Post. It will push information to some third-party devices or software that are compatible with ours. Information can be pushed by RTSP, TCP or HTTP.

More information about LPR Message Post, please refer to Milesight-Troubleshooting-Integration between LPR Camera and NVR(VMS).

Step4: Don’t forget to click [Save] after finishing all settings.

2. List Management

Two License types:

ANPR

No License plates type will be shown if the license plate does not exist in Black/White list. However, you can right click the license plate information to quick add it to Black/White list or delete it from Black/White list.

ANPR

Besides, you can click the license plate information to check the latest X seconds (10s~20s) video.

ANPR
Notes:

• X = 10 + Pre Record Time

   You can set Pre Record Time in Storage -> Video Record -> Record Settings interface.

ANPR

Then NVR will record when license plate is detected.

Notes:

Generally, record action is triggered by event. If you just enable ANPR function without enabling Black List/White List/Visitor modes nor setting record action, it means you just enable the function while record action is not set. Then no record will be triggered. So it is necessary to do all above three steps if you want to trigger record action.
