Ⅰ、About Milesight Radar AI LPR Camera

Milesight innovatively combines 3D Radar, AI, and LPR technologies to create a camera that can identify vehicles and read plates accurately and precisely, providing extra real-time data on vehicle position, direction, speed, etc. The all-in-one Radar AI LPR camera is easy to install as the 3D radar module is already integrated into the camera directly, realizing the hassle-free traffic flow monitoring solution.

Ⅱ、Installation Considerations

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

A. Recommended installing the camera in front of the vehicle:

It is recommended to mount the camera on a gantry or mounting bracket to ensure the camera captures the full view of the vehicle.

③: Detection distance of the radar module is up to 90m. Please ensure that the detection target is within the detection range.

Ⅲ、How to Set Radar AI LPR Camera

The following introduction is based on the LPR version: T_45.8.0.3-AP-r6. Devices can be updated to the latest version prior to setup. Firmware Download|The Latest Innovation|Milesight

Step1: Adjust the Zoom length of the lens.

It is recommended to adjust the zoom length to cover the road range to be detected, as shown below.

Then, adjust the detection sensitivity of the radar module; level 1~4 is available. The easier the target is to be detected. Users can adjust the detection sensitivity as needed to avoid some missing or false detection, such as false detection caused by rain hitting the radar board.

Figure 7 LPR - Speed Monitoring Page

[Installation Location]: Please fill in the installation position of the camera on the road. The range is -12 to 12 meters, and the default is 0.

If the camera is installed in the middle of the road, fill in 0, otherwise, fill in the corresponding offset distance. It should be noted that the installation position needs to be confirmed as a positive or negative number. With the center of the road as the zero point, if the camera is installed on the left side of the road, it is defined as a negative number, and if it is on the right side, it is defined as a positive number.

Taking the scene in Figure 7 as an example, the camera is installed in the middle of the road, so fill in 0.

[Installation Height]: Please fill in the installation height according to the actual installation height of the camera, and the range is 2 to 7 meters.

[Radar Tilt Angle]: Please fill in the Radar Tilt Angle according to the actual installation angle between the camera's field of view and the horizontal. The adjustable range of radar angle is 0-15°.

[Camera Direction]: Please fill in the angle between the direction of the camera installation and the road; the angel range is -30°~30°, and the default is 0°.

When the camera is parallel to the road, enter 0. Turn right is positive, and turn left is negative, as shown below.

Figure 10 Camera Direction

[Radar Test]: After completing the above configuration, you can click the test button. Then, the above configuration will be automatically saved, and the radar module will start to test with the maximum sensitivity and maximum detection range,which is not limited by the lane configuration. In this way, the user can flexibly adjust the configuration according to the position of the target in the coordinates to achieve the most matching configuration.

Therefore, please ensure that the position of the red line in the video is the actual horizontal distance from the red line to the radar in the scene, to facilitate better matching between the LPR data and Radar data.

Figure 12 Trigger Distance Settings

l Measure by the radar coordinate map. After setting the trigger line in the actual scene, first， fill in an estimated trigger distance. When the vehicle passes the trigger line, pause the radar coordinate map to locate the target position in the radar coordinate map, and then you can get the correct trigger distance.

Figure 14 Measure by Radar Coordinate Map

[Speed Unit]: Select the speed unit as km/h or mph to meet the needs of customers in different regions.

[Match Lanes and LPR Detection Regions]: Please match the LPR detection region and lane one by one according to the actual scene.

[Radar Message Post Settings]: It supports the compatibility of radar data with back-end software via TCP, such as Milesight VMS Enterprise.

After completing the Road & Installation Settings and Detection Settings, this information will be dynamically matched with the coordinate map in the lower left corner, and the detected target will also be dynamically displayed on the coordinate map, which is convenient for users to view the detection results in real-time.

Step5: Schedule Settings.

Set the effective time of traffic detection.

Step6: Traffic OSD Settings.

Customers can choose the information that needs to be displayed in Live Video and the display format, such as color, size, etc.

Figure 17 Traffic OSD Settings

[Show OSD]: Users can choose the information they want to display in Live Video, including Speed, Direction, Distance, Azimuth, and Vehicle Counting.

[Font Size]&[Font Color]: The font size and color of the OSD display, the default size is Medium;
When Speed, Direction, and Vehicle Counting are checked, the Live View interface is displayed as shown in the figure below:

Figure 18 Live Video Interface

[Counting Reset]: Click the "Reset" button to reset the vehicle count manually.

[Enable Auto Reset]: It automatically clears the vehicle count at regular intervals (Just reset the OSD count for Live Video). After it is enabled, the interface is shown in the figure below. Just follow the prompts to set it.

Step9: Alarm Action .

This part is the same as the regular alarm settings. For details, please refer to the Milesight Network Camera User Manual. Here are two examples of alarm actions for your reference.

l OSD Blink

You must enable the corresponding OSD first, as shown in Figure 19. And then when an alarm is triggered, the OSD information will flash and alarm, and you can also set the duration of the OSD Blink Time, which supports 1~10s.
