New AI camera technology.
Recognition software is build into camera for peoples and vehicles. If either objects are recognised between the guide lines it will sound beeping alert tone from the internal speaker mounted in the drivers cabin.

Our 7" inch Monitor and RKW7 can display the video signal.
