Two different detection modes can be used with the Vaxtor ALPR Apps.
Freeflow: license plate is detected if it appears in the detection area
Signaled: Vaxtor ALPR app gets a MxMessage trigger for a one-time detection at the time the MxMessage arrives in the app.
this tutorial explains how to set up the configuration for this.
In this case, the camera receives a signal input and sends a MxMessage to the Vaxtor app so that it starts a detection when a signal input is received.
Admin-Menu → MxMessage System → Message Profiles for Action Groups
Add a new Profile
the default MxMessage in the Vaxtor app for a signaled detektion is: trigger
However, you can use any MxMessage, which must then be customized in the Vaxtor app afterwards.
It is important to set the Message Range to Local!
Setup-Menu: Event Overview
in this case we use a Signal Input as Trigger Event.
You can also use an IP-Notify Event for example which will be send from 3rd Party software.
Setup-Menu: Action Group Overview
Add new group
Select the triggering event in the Event Selection
Add a new action and select your MxMessage Profile which you have created in the first step
Setup-Menu: Certified App Settings → Vaxtor ALPR
Working Mode: signaled
Trigger Message: trigger (or enter your own message which you have define in the MxMessage Profile for Action Groups)
Now, the Vaxtor app only detects a license plate once at this point in time when the MxMessage arrives.
and only if the signal input (event) is present in the camera.
