Product Documentation and Other Resources

Highlighted Features

Read all license plates of a geographical region

Carmen® Mobile will accurately return all license plates from its region (e.g., Europe, North America). With this app, there is no such thing as an unrecognizable license plate.

Perform accurate ANPR at up to 180 km/h (112 MPH)

Perform ANPR from a moving car, even at a speed difference of 180 km/h (112 MPH). All traffic situations are covered, i.e., vehicles approaching/moving away, parked on the side, etc.

Upload events easily to your chosen server

With the Carmen® Mobile app, uploading events is easy. All you need to do is provide the destination server (GDS, FTP, or REST API), pick the data to be included in the event package, and let the app do the rest.

Select automatic or manual capture

The app automatically recognizes vehicles in an image stream to capture still images of them, but you can also switch to manual mode to take photos of vehicles. Carmen® Mobile also automatically preselects pictures to ensure cost-effective operation.

Use ready-to-use presettings

Aside from your custom settings, Carmen® Mobile offers five preset modes for the following situations: in motion, in a fixed position, parking, handheld, and above a highway. You can further customize all these presets to your needs.

Create your own alert lists

Create your own customized hotlists to receive alerts for specific events directly from the app. Capture traffic and parking violators and other vehicles of interest right on the spot with Carmen® Mobile.

Decide what information you need

Event packages may include an overview, a picture of the vehicle, and even a short video. You have the option to only upload hotlisted vehicles to the server.

Get instant feedback for each capture

Get instant feedback on the success of image capturing via vibration and/or sound signals. Both signals can be turned on and off in all modes.

Save bandwidth by working offline

Images and metadata can be collected without 4G, saving you battery time and money. Events then can be processed and uploaded at a later time on a Wi-Fi connection.

Process live feed, images or prerecorded videos

A wide range of formats (RTSP, RTPM, MJPEG, MP4) and sources supported, such as live video feed, a still image, a video uploaded to the app from an external camera.

Adjust camera settings to your preferences

Additional settings of the phone's camera allowed, such as exposure time and brightness, a flashlight, and separate modes for performing ANPR during the day and night.

Supercharge your existing Android app with ANPR + MMR

Integrate Carmen® Mobile into existing systems. Launch the app from your own app and get ANPR and MMR data straight from the live video stream.

Validate data by digital signature

Use the digital signature to authenticate ANPR results. Verify who created the event and prove that event data hasn't been tampered with.

Process image streams from any source

The application can process any image stream displayed on the mobile phone screen, regardless of the source. This means you can perform ANPR on any native video application such as VLC or display screens of drones, action cameras, and more.

Get email notification of alerts

You can optionally receive email notifications of your customized alerts. The email will include plate data, timestamp, reason for alert, and the image.
