Mounting On A Pole Upstream From The Stop Bar; Choosing A Mounting Height; Troubleshooting Your Installation - Wavetronix SmartSensor Advance User Manual

The SmartSensor Advance Extended Range is recommended
˿
at this location, because some of the sensor's range is used to
cross the intersection.
Allows you to aim the sensor directly at the lanes of interest
˿
without rolling.
Great for applications like queue management where a zone at
˿
the stop bar is needed.
Effective for medium-speed approaches or where dynamic red
˿
extension will be used in tandem with green extension.
Watch out for poles, mast arms or signal heads that could
˿
potentially cause occlusion.

Convenient if power is supplied to an existing pole/luminaire
˿
and a wireless communication link can be established.

Choosing a mounting height

The minimum recommended mounting height is 17 ft. (5.2 m) and
the maximum is 40 ft. (12.2 m). Mount the sensor as high as possi-
ble to reduce the chance of same-lane occlusion.

Troubleshooting your installation

Mount the sensor as high as possible to help avoid occlusion.

Chapter 1: Choosing a Mounting Location
Definition. Mounting
height is the distance
between the sensor
and the road's
height, not the
bottom of the pole. If
installing a new pole,
remember that part
of the pole will likely
be below ground.
