The Virtual Loop vehicle detectors are a great solution for sites where ground loops cannot be installed, such as when the road surface is damaged or unsealed, where there are cobble stones, or above drains or pipes. The OVS-02GT detects the presence of a small or large stationary or moving vehicles within 8 meters while ignoring human traffic. It is easy to install; unlike ground loops, no civil works are required, and the device is mounted 500 mm from the ground. The OVS-02GT connects to an automatic barrier, slide gate, swing gate and industrial door. All of setting is done by smart phone App which support iOS and Android. It is possible to set all of setting by App and has 11 default setting for barrier, slide, swing gates. A lot of parameters adjustment, the calibration and the sensor status could be set by the App.
