Installation Angle Considerations

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

1. Installing the camera in front of the vehicle (Recommended):

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

2. 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. The Youtube video in the link below has actual installation suggestions for LPR Camera, which can be used as a reference.https://youtu.be/u88gNAdrJnM

3.Countries/Regions that support ANPR

Backed up by strong R&D strength and accumulated expertise in LPR applications, Milesight Intelligent Traffic solution can be well applied to broad regions and countries worldwide. We've now covered a wide range of areas including:

4. How to set ANPR with Milesight Network Cameras

The following introduction is based on the latest version of LPR T_61.8.0.4;

Before setting it up, you can update your device to the latest version.

You can download the latest firmware in the link below：

http://www.milesight.com/support/download 

4.1General

Step1: Go to “Traffic” -> “LPR”，after log in the web.

Check the “Enable LPR” checkbox, and you can draw the screen to select the interested areas. There will be shown in the blue box below.  

[Country / Region]: Select a country within the appropriate region.

[LPR Image Mode]: In order to recognize the attributes of vehicles 

and license plates in different environments, [LPR Image Mode] can be enabled, a special exposure mechanism for license plate recognition that can effectively suppress the exposure of car lights at night for night license plate recognition.

Achieve the best effect of LPR night recognition by adjusting different parameter levels.When LPR picture mode is enabled, backlight, exposure and day/night switching parameters will be set to special values.Minimum shutter for each level: 1- 1/250, 2- 1/500, 3- 1/750, 4- 1/1000, 5- 1/2000.

The picture below shows the night recognition effect after turning on the LPR Image Mode. 

Note：

For PE platforms (devices with the model suffix PE), [LPR Image Mode] is enabled by default and does not require configuration, so there is no Image Settings option under General.

Step2: Detection Region

[Set LPR Detection Region]: You can set up to 4 ROI areas by drawing the 

screen. It is recommended to draw the ROI detection area at the center of the screen to ensure the recognition of the vehicle after it fully enters the screen and the integrity of the vehicle screenshot. 

Notes

• The optimal license plates width for recognition is within 100-200 pixels. 

• In order to obtain better performance,the lens can be properly zoomed in 

so that the vehicle is in the center of the camera's field of view to ensure 

clear recognition of the license plate. 

Step3: Detection Settings

[Detection Mode]: If you choose the “Plate Priority”, the camera will first capture the license plate information of the vehicle entering the screen.If you select the “Vehicle Priority”, the camera will first locate the target vehicle and then recognize the license plate to avoid some false detection.

Note:

1. Vehicle priority mode can identify vehicles without license plates.

2. Vehicle priority: Adopt the "vehicle priority" vehicle identification method, mainly based on the appearance characteristics of the vehicle for automatic identification, such as model, body color, vehicle logo, etc., this method can be applied to many different types of vehicles;

3. License plate priority: The vehicle identification method of "license plate priority" is adopted, and the automatic identification is mainly based on the license plate information on the vehicle, so the accuracy of license plate recognition is high.

[Detection Trigger]: If you choose “Always”, camera will always detect the license plate. If you choose “Alarm input”, camera will only detect the license plates when Alarm Input is being triggered.

Alarm Input trigger can be used in entrance & exit management for gate control, parking lot management and other scenarios. The Alarm input interface of the LPR is usually connected to the Ground loop coil. When a vehicle passes by, the Ground loop coil will be triggered and transmit a signal to the Alarm input interface of the LPR Camera, thereby triggering the IPC to recognize the license plate information.

[Repeat Plate Checktime]: Set the time interval for repeatedly reading license plates to effectively avoid duplicate identification of parking vehicles.

[License Plate Serial Format]: License Plate Serial Format function supports formulating identification rules and can automatically do further processing, filter license plates in non-compliant formats to achieve more intelligent and accurate license plate recognition.

Through the License Plate Serial Format, you can set special rules to filter out the corresponding license plates, and only the license plates that meet the rules will be automatically displayed and displayed on the real-time view interface.

For example, we can set the number of license plate characters to 7 characters, and the format is "A*****". When we enable "Filter number of characters", only license plates that match the 7 characters of the license plate and start with a letter will be pushed and displayed.

Note: PE platform models support 30 license plate rules.(For PC platform devices, 10 are supported).

[Attributes Identification]: Check Plate Color, Vehicle Type, Vehicle Color, Vehicle Brand, Detection Region, Direction, Country, Region or All to enable Attributes Identification, it will display the corresponding information on the logs interface.

Step4: Schedule settings

Set the effective time of license plate recognition.

Step5: LPR Message Post Settings

For PC platform, 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 transmitted by RTSP, TCP, HTTP.

For PE platform, this function has been separated into a separate module named Data Transmission. At the same time, MQTT and Metadata are added to the data push type.

Note：

1. If you need to add LPR Camera to Milesight NVR/CMS/VMS Enterprise, you must select the TCP type to transmit data to the back-end software and enable Original mode in Data Settings.

2. If you add LPR Camera to MS NVR/CMS/VMS Enterprise through mapping, then TCP ports also need to be mapped.

3. If your LPR Camera’s firmware version is later than 61.8.0.3-r10 and model suffix has -E, you can enable Automatic Retransmission which allows for automatic re-upload of LPR data during network reconnection after disconnection. The resumed data include regular LPR and Traffic events, ensuring the integrity of device data and meeting data security requirements.

SD card insertion is necessary for this feature to work

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

Step6: Don’t forget to click “Save” after finishing all settings.

4.2Advanced

In the interface, you can set display information on snapshot of license plate recognition and also customize the file name of snapshots which are uploaded via FTP or Email or stored on local LPR Picture File Path.

[Snapshot OSD]:Set the screenshot OSD options.

Each time when an item is checked, the list will add the item row, including the item name and sorting operation.  You can click

Notes

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

• In order to obtain better performance,the lens can be properly zoomed in 

so that the vehicle is in the center of the camera's field of view to ensure clear recognition of the license plate.
