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.

III. Countries/Regions that support ANPR

Currently, we have three kinds of LPR, including LPR1, LPR2 and LPR3. LPR1 is used in Asian region, LPR2 is for European region, and LPR3 is for Korea. It covers over 70 countries and regions.

LPR1:

LPR2:

CIS (former Soviet Union)

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.

[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”.

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

[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.

[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.

Step3: Detection Settings and LPR Message Post 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.

[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

3. List Management

Make a license plate list for your own NVR ANPR system.

Upload license plates and set them with different license type here. 10000 License plates can be added at most.

Kindly note that the list is exclusive for NVR, working with all LPR cameras you add. It won’t synchronize with the list on camera side.

There are two methods to add license plates:

(1) Add one by one.

Step1: Click the “Add” button.

Step2: Input the license plate and select license type.

Step3: Click OK and then the license plate will be added into the list.

(2) Batch upload by importing template.

Step1: Click Download Template button, select USB device folder and click OK to download Template.

Step2: Input all license type and license plate number as Template shows.

Step3: Click Import button, select the file and click OK to add all license plates into list.

4. Black/White/Visitor List Mode

We provide you three modes for better event management.

Black List Mode: Manage event for license plates in black list.

White List Mode: Manage event for license plates in white list.

Visitor Mode: Manage event for those license plates do not have license type.

Steps for settings:

Step1: Enable Black List Mode/White List Mode/Visitor Mode as your demand.

Step2: Set effective time for the mode to work.

Step3: Set actions you need including Audible Warning, Email Linkage, Event Popup, PTZ Action, Alarm Output and Trigger Channels Record.

Notes:

Do not forget to enable these modes, set effective time and record action for corresponded mode, so that you can get real-time video when license plate is detected (Effective time and record action is enabled by default.). You can refer to How to check ANPR record part for detailed record settings.

5. Professional LPR Liveview Interface

At the beginning, you need to switch the preview mode to ANPR mode.

There are two methods to enter live view ANPR Mode:

(1) Right click the mouse and select ANPR Mode as preview mode.

(2) Select ANPR Mode on live view bottom tool bar.

After entering ANPR mode, the real-time license plate information will be shown on the left of the interface once it get detected.

License plate information includes Plate Snapshot, Channel Name, License Plate Number, Detected Time and Plate Type.

Two License types:

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.

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

Notes:

• X = 10 + Pre Record Time

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

• Make sure that HDD is available on NVR and correct record settings is made, so that you can check the record on live view. Please refer to How to check ANPR record part for detailed record settings.

• Make sure that NVR can get the license plate information. Please set TCP as Post Type which is the default mode. It can be set in Camera web page -> Advanced Settings -> ANPR -> Settings interface.

6. Set/Check ANPR Record

Step3: Set Effective time and Trigger Channels Record action of your selected mode (Full effective time and trigger channel record are set by default).

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.

(2) Check recording

In Playback

Step1: Entering Playback -> Event Playback -> Smart Analysis interface.

Step2: Input corresponded information and click search button to search.

Step3: Click record to play the video searched out.
