How to install the application?
You need the installation package. Please follow the link for the latest version on the app. Download Link
Check the compatible firmware version and upgrade the camera if necessary.
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 urgent need
Follow the Installation Guide, section ANPR Application > Application Installation
Where can I get the activation key?
Please contact your distributor for the new installations.
If you are going to re-install the application, reset camera, please store the activation key before doing that. Here is the way to do that:
-log in to the camera
-follow the link in your browser
http://<camera IP>/stw-cgi/opensdk.cgi?msubmenu=manifest&action=view&AppID=NumberOkEdgeHanwha
-look for <LIBRARY_ACTIVATION_KEY> section and store the key from there
You can use it on the same camera every time
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 ANPR performance; SD-card health; camera’s firmware version is compatible
Do I need an SD-card?
The Sd-card is needed to store the images of the events. Also, it is mandatory to have SD-card installed and operational to send data via HTTP integration. You do not need a lot of storage capacity, as the application will use several hundreds of megabytes depending on the image scene.
I do not see event’s images in the application
Please check the following:
-SD-card is installed in the camera
-SD-card is activated and formatted to VFAT
-SD-card is class 10 and provide the necessary speed to operate by the camera and the application
Do I need to configure any reactions?
Please configure reactions only when you actually need them. Like, sending data to NVR or barrier management through built-in relay.
“Save to SD-card” reaction would force the app to store images into an additional folder on the SD-card which is only accessible if you remove the card from the camera. Use this reaction only when you do not have access to the installation point and you plan to eject the data from time to time physically.
How to obtain logs?
In some cases additional information needed to check the issues with the application.
There are two types of logs: in-camera, 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 + <number>
where <number> is in range 1..7
The default level is 4.
Please keep in mind that 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, SD-card usage and could affect application’s performance.
Port 6162 is required to download the logs, if this not accessible via a remote connection use below method
From v 5.1.23 on wards, logs can also be accessed via:
HTTP://<Camera IP>:port/home/setup/opensdk/html/NumberOkEdgeHanwha/logs/NumberOkEdgeHanwha_logs.log?AppName=NumberOkEdgeHanwha
How to add a camera to NumberOk Meta?
How can I delete all Number Plates for the SD Card to have an empty Camera?
You can format the SD-card, but that will only remove stored images without removing the events from the database.
Re-installing the app would clear the database.
How many events can be stored?
The application stores up to 1000 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:
- 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
- AGC (automatic gain control) is set to Normal or High, which results in noise and affects recognition performance
- shutter speed is low (slower than recommended 1/700 or event than 1/200 which can be used for slow vehicles)
- 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.
- Camera does not switch to the B/W mode during nighttime, as in case of high illumination it can stay in Colour mode, but the conditions would be poor for plates reading and IR would not affect the image
How to activate the application?
The activation key is needed for application launch. Activation process step by step is covered in Installation Guide, section ANPR Application > Application Setup > Activation
Please make sure to use one of the Recommended browsers.
Also, browser cache should be cleared after the activation process (Ctrl+F5)
SD-card installation
Follow your camera manual for SD-card installation steps. Use instructions in the Installation Guide, section Camera Settings > SD card for SD-card configuration
We recommend to stop the application during SD-card installation and formatting.
Application does not recognise licence plates
Check if the application is installed. Follow those guides How to install the application and I would like to try your solution
Check whether the application is running.
Check the activation status in the application's Settings tab.
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
Image requirements
Plates should fit the following restrictions for better recognition :
-clearly visible and readable by human
-plate width should be in range of 130-400 pixels on a picture
-plate roll angle is less than 5˚
-plate pitch and yaw angles are less than 30˚
Check for details in Installation Guide, sections Camera Mounting,
ANPR Application > Application Setup
> ANPR Settings - Recognition Area and Plate width,
ANPR Application > Application Setup > Recognition zone - Motion paths
Recommended browsers
We recommend to use Chrome, Firefox, Safari. Check details in Installation Guide, section Camera Settings > Important note on web browsers
False recognition: grass / asphalt / textures detected
- Configure the recognition area in the Settings tab to avoid appearance of unnecessary texture and limit it only to plates appearance zone. Follow the steps in Installation Guide, section
ANPR Application > Application Setup > ANPR Settings - Recognition Area and Plate width
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
Follow the recommendations in Installation Guide, sections
Camera Mounting >
Proper installation - Best practices,
Camera Mounting
> Installation don’ts - Worst practices,
Camera Settings > Video setup
False recognition: small objects detected
Change minimum plate width in Settings tab
Use Installation Guide, section
ANPR Application > Application Setup > ANPR Settings - Recognition Area and Plate width for details
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
