TROUBLE SHOOTING

How to install the application
You will have Wisenet RoadAI application pre-installed. In case you need to manually install the app (e.g. update app with the latest version) the installation package is required from Hanwha Teach-in website.

If you are upgrading the existing application it is recommended to stop the app before installing the newer version. Check the compatible firmware version and upgrade the camera if necessary. Check that you have one of the supported camera models: PNO-A9081RLP, PNV-A9081RLP, PNB-A9001LP Please keep in mind that the latest firmware version support could lag for a few weeks, so do not rush to upgrade the camera without confirmation of compatibility.

Applications restarts from time to time – is that normal?
Both your camera and the application have protective mechanisms to avoid crashes and stalling. Those watchdogs could restart the application. Please contact the support if the situation happens too often.
Check that built-in video-analytics are disabled, as they consume camera’s resources and affect application performance; micro SD-card health; camera’s firmware version is compatible.

Do I need an micro SD-card?
The micro SD-card is needed to store the images of the events.
Also, it is mandatory to have micro SD-card installed and operational to send data via HTTP(s) integration and store application’s logs.
Your camera have an micro SD-card(32Gb) pre-inserted. In case you need to change it, please select a compatible option (32Gb at least, class 10).

I do not see event’s images in the application
Please check the following:

  • Micro SD-card is inserted in the camera
  • Micro SD-card status is OPERATING in the About tab
  • Micro SD-card is class 10

Try to restart the camera to re-initialize the microSD-card if all the above are OK.

How to obtain logs?
In some cases additional information needed to check the issues with the application.
There are two types of logs: 1) in-camera, 2) in-application ones.
In-camera logs are accessible through camera configuration in System>Log section.
In-application logs could be downloaded via your browser after hitting this combination, while on the app’s page: Ctrl +Alt+ Shift+ L
Also, you can change the log-level (the amount of stored data) with Ctrl +Alt+ Shift+ , where is in range 1..7.
The default level is 4.
Please keep in mind that micro SD-card is needed to store and download logs.
Also, log-levels higher than 4 provide massive amounts of data, so would both increase the log size, micro SD-card usage and could affect application’s performance.

  • Alternative method to access logs if camera is hidden bedding the router is to use the following link
    http:///home/setup/opensdk/html/WisenetRoadAI/logs/WisenetRoadAI_logs.log?AppName=WisenetRoadAI

  • In some cases more details could be requested.
    Useful links to check application status:
    http:///home/setup/opensdk/html/WisenetRoadAI/IPCameraManifest.xml

  • The application configuration is stored here
    http:///stw-cgi/opensdk.cgi?msubmenu=metaframeschema&action=view

  • Check if integration with VMS (SSM, Milestone, Genetec) is enabled
    http:///home/setup/opensdk/html/WisenetRoadAI/metadata.log

  • Check the latest integration event
    http:///home/setup/opensdk/html/WisenetRoadAI/schema.log

  • Check the integration message schema
    http:///stw-cgi/debugcgi?msubmenu=data&action=view

  • Check internal camera debug information

How can I delete all Number Plates from the SD Card to have an empty database?
You can format the micro SD-card after removing it from a camera. That will remove stored images without removing the events from the database. Re- installing the app would clear the database. Also, you can import empty database in the About tab.

How many events can be stored?
The application stores up to 10.000 events in the camera. You can increase the number of events by saving them on the back-end side via different integration types available.

Bad recognition at night. How to fix that?
This might be result of:

  1. Improper focusing. Consider that the area with sharp details varies during daytime and nighttime. You can even configure two setups for day and night recognition with different focus.
  2. AGC (automatic gain control) is set to Normal or High, which results in noise and affects recognition performance.
  3. Shutter speed is low (slower than recommended 1/300)
  4. IR power is not configured properly (either vehicle is too far and IR is not enough or too close that plates are over-exposed; also closer to frame borders a vignette effect is strong). Consider using external IR for longer distances or higher vehicle speeds.
  5. Camera does not switch to the B/W mode during nighttime, as in case of high illumination it can stay in Color mode, but the conditions would be poor for plates reading and IR would not affect the image.
    Application does not recognize Make, Model and color at night. This is normal. With the help of IR, it can read only the plate numbers. Occasionally it gives the make and model but it may not be the exact match due to poor lighting conditions.

Do I need to activate the application after installation?
You do not need to activate the application in any way – you can install it on any of the supported camera models and use it right away.

Application does not recognize license plates, vehicle models

  • Check if the application is installed. Follow the installation guides to configure the whole setup properly.
  • Check whether the application is running.
  • Check the Image requirements in case you have a video in a preview, but do not have recognition.
  • Do you use a supported browser? Recommended browsers.
  • Use Plate Size checker and Freeze Frame tools in the settings tab to check if the plate size, roll angle, positioning are valid.
  • Change the application resolution to FullHD if plates are too big or to 4K if they are too small. Adjust plate’s size with camera’s zoom.
  • Make sure to start the application. It is recommended to use the ‘Enable Auto Start” function for convenience.
  • If you go in to the Wisent Road AI app with out actually starting the app, you only get a black screen with Wisenet Road AI.

Image requirements
Plates should fit the following restrictions for better recognition :

  • Clearly visible and readable by human
  • Plate roll angle is less than 5˚
  • Plate width should be in range of 130-350 pixels on a picture
  • Plate pitch and yaw angles are less than 30˚

Check for details in Installation Guide.

Recommended browsers
We recommend using Chrome, Firefox, Safari. Check details in the Installation Guide, section Camera Settings > Important note on web browsers

False recognitions: grass / asphalt / textures detected

  1. Configure the recognition area in the Settings tab to avoid appearance of unnecessary texture and limit it only to plates appearance zone.
  2. Use manual focusing in camera settings and adjust focus to provide a sharp picture of license plates in the area they appear.

False recognition: low picture quality
Try improving picture quality through camera settings: Sharpness, focus, exposure

False recognition: small objects detected
Change Area of Interest in the Settings tab to avoid detecting small plates. Use zoom or in-app resolution to adjust.

Can’t see video in browser

  1. Check whether you use supported browser if you are in the same network with camera.
  2. Port 6162 from camera should be forwarded through router to view video from remote network.

Recommended Settings does not apply
Some of the camera’s settings are interconnected. Try to reset Video setting to default and use Recommended Settings button, or just follow the Installation Guide to set the camera manually.

Region selection, resolution selection does not apply
Changing region and resolution will apply to GUI firstly. You need to restart the application in the Open Platform section of camera setting to fully apply changes.

Not all search results are displayed
The search results are currently limited by transmitting buffer size providing approximately 800 latest results. Please specify your search parameters to narrow down the result by using date/time filter or other vehicle criterias.

How can I integrate with Milestone/Genetec
Please use Hanwha Techwin’s AI plug-ins for your VMS to obtain vehicle recognition events from Wisenet RoadAI. No additional settings needed on the application side.

What happens if I reset camera
You will not lose the application setup or data if you reset camera keeping Network & OpenPlatform parameters. Otherwise, the application will be removed with only event images stored on the SD-card. The only way to obtain images is to remove card from the camera in that case.
We strongly recommend export application settings and database in the About tab prior reset or application reinstallation/update.
If you hard reset the camera through the physical reset button, you have to re-install the application.
