TROUBLESHOOTING
How to install the application
You will have RoadWatch application pre-installed. In case you need to manually install or update the app.
Please find it at the Hanwha Vision 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.
Please keep in mind that the latest firmware version support could come in a few weeks, so do not rush to
upgrade the camera without confirmation of compatibility.
Application 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 is disabled, as it consumes the camera resources and affects application
performance; micro SD card health; camera’s firmware version is compatible.
Do I need a 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 operating to send data via HTTP(s) integration and store the application 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).

TROUBLESHOOTING (CONTINUED)
I do not see event images in the application
Please check the following:
-Micro SD-card is inserted in the camera
-Micro SD-card status is OPERATING in the Settings tab
-Micro SD-card is class 10 and above
Try to restart the camera to re-initialize the microSD-card if all the above is 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 by following the addresses below.
Keep in mind that micro SD-card is needed to store and download logs.

Check if integration with VMS (SSM, Milestone, Genetec) is enabled
http://<CameraIP>/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 Settings tab.
30 | RoadWatch application User Guide
How many events can be stored?
The application stores up to 100,000 (WN7) or 1,000 (WN5) events in the camera. You can store more 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 minimum 1/500)
4.IR power is not configured properly (either a vehicle is too far and IR does not illuminate enough, or is too close
that plates are over-exposed; also the closer the plate to the frame borders, the stronger is a vignette effect).
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 perform Make, Model and Color recognition at night. This is normal. With the help of IR,
it can only read the plate numbers. Occasionally it gives the make and model but it may not be the exact
match due to poor lighting conditions.

TROUBLESHOOTING (CONTINUED)
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 licence plates, vehicle models
Check if the application is installed. Follow the installation guides to configure the whole setup properly.
Check if application is running.
Check the image requirements in case you have a video in a preview, but do not have recognition.
Make sure your browser is supported.
Use Plate Size checker and Freeze Frame tools in the settings tab to check if the plate size, tilt angle, positioning are
valid. Change the application resolution to FullHD if plates are too big or to 4K if they are too small. Adjust the plate size
with the camera zoom.
Make sure to start the application and opt-in the ‘Enable Auto Start” setting.
If you go in to the RoadWatch app without actually starting the app, you only get a dark screen with the logo.
Image requirements
Plates should fit the following restrictions for better recognition :
-Plate width should be in range of 130-350 pixels on a
frame
-Plate vertical and horizontal angles are less than 30˚
-Clearly visible and readable by human
-Plate tilt angle is less than 5˚
Check the Installation Guide for details.

Recommended browsers
We recommend using Chrome, Firefox, Safari. Check the details in the Installation Guide, section Camera Settings >
Important note on web browsers
False recognitions: grass / asphalt / textures detected
1.Configure the Region of Interest 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 Region 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.

TROUBLESHOOTING (CONTINUED)
Recommended Settings does not apply
Some of the camera settings are interconnected. Try to reset Video settings 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.
How can I integrate with Milestone/Genetec
Please use Hanwha Vision AI plug-ins for your VMS to obtain vehicle recognition events from RoadWatch.
No additional settings needed on the application side.
What happens if I reset the 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 exporting application settings and database in the Settings 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.
