Vehicle Detection Sensor


Vehicle Detection Sensor VIRTUAL LOOP OVS-01CLB
  • OVS-01CLB[Flush mount]

Available in Japanese market only

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.


Microwave and ultrasonic combination technology provide a stable vehicle detection.
This microwave FMCW technology enables a presence detection as well.

Presence detection

Since the microwave module is using both Doppler shift and FMCW technology, it enables to detect the presence of vehicle as well.

No need to burial underground.

No need to burial underground.

Since no in ground or on ground device required like induction loop. Construction period can be shorted.

Strong against rain, wind and snow.

Strong against rain, wind and snow.

Automatic sensing adjustment enables to be used at outdoor.

Not affected by vehicle color.

Not affected by vehicle color.

Technically no influence for vehicle body color.

Only detects vehicles.

Only detects vehicles.

Human cancellation enables to ignore human and detect vehicle only. (patent pending)
