The ZONE function enables speed reduction at gates. For this purpose, the stationary set M is installed near the gate and operated with 230 volts. Each antenna is installed on one side of the gate and freely configured. Vehicles equipped with ELOshield automatically reduce their speed when entering the zone and increase it again when leaving. Optionally, ELOshield can also open and close the gate automatically when connected to the gate control system. The system can also be extended with projectors that indicate whether there is a vehicle on the other side of the gate.
