The Virtual Loop 2.0 is a Vehicle Presence Sensor for use on Gates and Barriers.

The advanced Distance Measuring Radar reliably detects vehicles of all sizes while ignoring nearly all human movement. Eliminate all the hassles of installing and servicing in-ground loops and give your customer reliable activation and presence for all their gate applications.
