Frequent Questions

From what distance can the motion detector pick up path activity?

The motion detector can be set up to detect path users at up to 75 feet from the intersection.

How accurate is the motion detector?

In our testing and in the field, we have a 100% success rate in detecting path users. A large animal will cause the detector to trigger, but in our opinion having the lights flash in this circumstance is a good thing. Our microwave detectors only detect trail users as they approach the crossing.

Why not use a push button instead?

A push button can be used in place of motion detection, or in combination with the microwave detector. Our research has shown that some path users will not bother to activate a push button when available. A push button works well in conjunction with the motion detector when a sidewalk intersects a path at a mid-block crossing.

Does the Cross Alert device alter traffic flow?

Absolutely not. Our intersection systems reinforce existing Right of Way rules for recreational trails and pedestrian crosswalks, which typically require the person crossing the road to yield the Right of Way to vehicles at intersections. This sign is a warning system that raises the awareness of vehicular traffic to the presence of path users at or approaching the intersection.

How long do intersection signs flash once triggered?

The duration that a Cross Alert sign flashes is completely configurable, depending on the needs of the intersection.

Will heavy rain cause false readings from the motion sensor?

No. We use microwave technology, which should only trigger on bodies in motion approaching the intersection.

What maintenance is required for these systems?

Minimal. Every 5 to 7 years the battery will need to be replaced. Most of our systems in the field have run problem free since installation. The system is designed for rapid component replacement in case of damage via a lightning strike or some other external factor.

How effective is the solar application?

For our solar system to work, we need on average 1 to 2 hours of direct sun a day. If an intersection is in dense shade, we offer a system that can be wired into the electric grid, or we can provide a larger solar panel which usually works well - even in dense shade.

What happens if the sun doesn't shine?

Under normal use, we can run for a month without any re-charge being applied to the battery.
