The FullHD mode can cover up to 2 lanes. Normally, setting recognition zone (see orange frame below) in lower half of camera view is sufficient and favours app performance. Best results are achieved when single row number plate width has fit the criteria. Greater width may affect performance. All the license Plate that are meeting the pixel criteria as below will be recognized in the selected area. · 130-300 pixels for regular EU plates · 80-300 pixels for US plates without stacked symbols (small ones) · 160-300 pixels for US plates with stacked symbols Color coded pixel counts are available in the settings section of Road AI. 2 INSTALLING AND POSITIONING CAMERA 2.1 Camera Installation NOTE: Refer to PNO-A9081RLP, PNV-A9081RLP, PNO-A9311RLP or PNB-A9001LP installation guide and follow the installation instructions. 2.2 Adjusting the Plate "Rotation" Angle For best results, check the angle of your plate compared to the horizontal angle and rotate the camera to less than 5° as shown below (Recommended Angle(s). Recommended Angle(s) 5°max NOTE: Refer to the "show plate grid" section available in Wisenet Road AI settings for assistance. 7 | LPR/ANPR Cameras Quick Reference Guide >5° 2. 3 LPR(ANPR)/ MMCR Specification LPR(ANPR) CAMERAS PNV-A9081RLP PNO-A9081RLP PNB-A9001LP (* with 50mm lens) PNO-A9311RLP LPR Usage Conditions Speed Description Lane Coverage Speed limit Min.

Field of View The below steps you will perform in the Wisenet camera configuration webpage · Configure camera so left and right are correct, not mirrored. · Set camera zoom to capture license plate · Adjust camera view angle so plate passes through the middle of the image. 1. Configuring Initial Camera Settings For proper operations, please, check and set properly: · Camera Date Time (+page 9) · IP settings (+page 10) · SD card storage (+page 13) · Camera exposure and focus (+pages 14~15) SSDR, WDR, DIS, Defog, AGC and anti-flickering features are good for human eye but affect computer vision performance and therefore setting these to the least possible effect or turning off strongly advised. 9 | LPR/ANPR Cameras Quick Reference Guide 3. 2 Configuring Initial Camera Settings (continued) [Date and Time] Date & Time A B 10 | LPR/ANPR Cameras Quick Reference Guide Choose AA Timezone and set Use daylight saving time as appropriate. Set B date and time or opt to synchronize with your PC or NTP server. NOTE: Wisenet Road AI app relies on these settings and if these are not set properly you may not see events in Wisenet Road AI app and events delivered to the outer systems may not contain proper timestamps. 3. 2 Configuring Initial Camera Settings (continued) [IP, DNS, Ports] IP & Port Proper IP, DNS and ports setting are important for: · NVR and other integrations · outside LAN access if required NOTE: Reboot the camera whenever IP address gets changed. 11 | LPR/ANPR Cameras Quick Reference Guide 3. 2 Configuring Initial Camera Settings (continued) [Go to App] Please go to App in camera open platform section. Open platform A To run the Wisenet RoadAI app, select the Open platform menu and click the AA Go App button in the Application name field. 12 | LPR/ANPR Cameras Quick Reference Guide 3. 2 Configuring Initial Camera Settings (continued) [Go to App] (Continued) Go to Wisenet Road AI application tab and select "Settings" from the pull down menu. A B C AA First, choose the Region. Choose the correct region that matches your country/region (Europe is set by default). For Europe/US region specify B the Preferred country/state to improve the ANPR accuracy. Save the settings. Click C Save settings. The application will restart for the selected region to take effect. After clicking Reload, wait for several seconds and reload the browser page. 13 | LPR/ANPR Cameras Quick Reference Guide 3. 2 Configuring Initial Camera Settings (continued) [microSD card] Your camera is supplied with micro SD card. B A SD-card is managed by the Wisenet RoadAI application and no user interaction needed. Please check the BA SD-Card status in the A ABOUT section of the Wisenet RoadAI app. Change the micro SD card if you see Error status. 14 | LPR/ANPR Cameras Quick Reference Guide 3. 2 Configuring Initial Camera Settings (continued) [Exposure adjustments] Use the recommended settings from the Wisenet Road AI application in most cases. But if you need to manually adjust here are the most common settings that affect the LPR performance.

However, even at low setting AGC produces noise that can ruin license plate images, also lighter areas tend to bleach out. See illustrations to the left. AGC off, BW, IR on 16 | LPR/ANPR Cameras Quick Reference Guide Start with turning AGC off. See the illustration to the left. Set AGC to low to improve plates visibility unless only other methods are helpful. Adjust zoom so that real plate pixel width is at least 130px. Consider adjusting recognition zone to be closer to the centre of the frame to avoid the IR vignette effect. NOTE: Do not use WDR as it decreases the shutter speed and may lead to the blur of the vehicles on footage. 3.3 Focus A unique feature of this camera allows you to select the plate area and hit a button to perform a "Simple Focus" on this plate area. 1 From the Video & Audio menu, select Focus setup. 2 Click and drag to draw an area of focus where the license plate is displayed. 3 Click the Simple Focus button to initiate a focus operation on the user-specified area. 1 Focus setup NOTE: The focus setting of PNB-A9001LP is related to the lens type, and manual focus is activated when using a manual varifocal lens. 2 The area indicated is not stored. If you need to perform a new Simple Focus, please draw a new area on-screen. Set the focus to have plates in the proper pixel size. · 130-300 pixels for regular EU plates · 80-300 pixels for US plates without stacked symbols (small ones) · 160-300 pixels for US plates with stacked symbols 17 | LPR/ANPR Cameras Quick Reference Guide 3. 4 Pixel width of License/Number plate 1 1 Spread or move license/number plate (vehicles) across the scene and take snapshots using web viewer capturing feature (Live ; Capture); 1 1 1 18 | LPR/ANPR Cameras Quick Reference Guide 3. 4 Pixel width of License/Number plate (Continued) 2 Use Plate Grid tool in the Settings tab of WisenetRoadAI and Freeze Frame feature to check whether plate fits the allowed range. 3 You can add an image from the Wisenet Road AI ; Settings ; Freeze frame to show the actual settings. 3 3 19 | LPR/ANPR Cameras Quick Reference Guide 3. 5 Observing PROPER Installation SCENE REQUIREMENTS: HAN 0123 > 130px License/number plate is more than 130px in width License/number plate is readable <30° Vertical angle is less than 30° Fig. 1 Daytime Fig. 2 Night time <5° <5° Tilt angle is less than 5° <30° Horizontal angle is less than 30° · good proportion to the frame width · well illuminated · sufficient contrast · acceptable tilt angle 20 | LPR/ANPR Cameras Quick Reference Guide · good proportion to the frame width · perfect IR power · sufficient contrast · critical yet acceptable tilt angle 3. 5 Observing PROPER Installation (continued) POSSIBLE IR RESTRICTIONS: The license/number plate is quite close to the frame boundary. You may notice a vignette effect. The license/number plate is closer to the centre of the frame. The plate is illuminated much better. Pay special attention to IR vignette effect (see illustration on the left) when setting up recognition zone. The closer to the center the more even illumination is. Also, in this particular case the real pixel width of the license/number plate is critically small. The Automatic Gain Control effect will be illustrated in camera exposure settings section. 21 | LPR/ANPR Cameras Quick Reference Guide 3. 6 Examples of IMPROPER Installation Too small (less than 130px wide) Tilt angle exceeds 5° Focus and Shutter faults Depth of field is insufficient to cover foreground license plates. Adjust the lens settings. 22 | LPR/ANPR Cameras Quick Reference Guide Improper focus settings. Adjust the lens. Blurry image due to long exposure. Fix the shutter speed to obtain sharper picture. 3. 6 Examples of IMPROPER Installation (continued) Exposure faults Insufficient light. Adjust exposure settings or provide additional lighting. Too much light. Either adjust the iris or shutter speed. Night time: dim the IR or set AGC to Low. 23 | LPR/ANPR Cameras Quick Reference Guide For more information visit us at Hanwha-Security.com Head Office 6, Pangyo-ro 319beon-gil, Bundang-gu, Seongnam-si, Gyeonggi-do, 463-400 Rep. of KOREA Tel : +82.70.7147.8753 Fax : +82.31.8018.3740 http://hanwha-security.com © 2024 Hanwha Vision Co., Ltd.
