Italrobotica 4 Canali allows you to open the License Plate Reading Systems in the 4-channel version of the EFFETI Impianti & Software.
For the app to work, just enter, in the app settings, the local IP of the PC where the Plate Recognition software is running and be connected to the same local LAN.
The app also works remotely, in this case just fill in the "External IP address" field inside the app with the public IP visible in the modem. If you do not have a static public IP, just register with any dynamic DNS service (no-ip, dyndns, etc ..)
For remote activation, open the UDP 3333 port on the router and direct it to the IP address of the PC where the Plate Recognition is running.
