Your brakes are trying to tell you something; listen to them!

At BrakeAudit we believe there are far too many injuries, deaths, and delays due to bad brakes. Inspecting them visually takes too long but listening to them is easy. We’ve developed systems that listen to the sounds that brakes make and use that information to send alerts when something’s wrong. We have decades of experience developing acoustic systems for the military, industry, and entertainment industries. Our systems are used by law enforcement, fleet managers, and vehicle manufacturers to reduce downtime, improve throughput, and save lives.

Does the vehicle need to be braking in front of BrakeAudit sensors?

Yes. Vehicles need to be braking where the wheel end are inside of the detection cone for BrakeAudit sensors. This cone is usually a 30 degree solid angle, and distance from the roadway is typically 10m or less. Places that can ensure braking include exit ramps at weigh stations and stop signs near facility exits, for example.

How are BrakeAudit sensors mounted?

BrakeAudit sensors can be mounted to any pole or other structure using suitable clamps. The sensors need to be angled so the wheel end passes within the 30 degree solid cone of sensing for each sensor; this means they can be mounted up to 3m high on any existing pole and pointed down at the roadway, for example.

What power and communications do I need for BrakeAudit sensors?

Power can be supplied through any voltage from 5V to 240V, both DC and AC. POE is sufficient. Communications are usually accomplished through internal cellular links. If data is sensitive, on-site processing can keep data from leaving the facility.
