Automatic reversebraking FAQs.

Automatic reverse braking is a safety system that detects objects behind a truck while it reverses and applies the brakes on its own. Global Sensor Systems’ Search Eye uses rear infrared sensors and the truck’s existing air brakes, so the truck stops even if the driver did not see the hazard.

No. They do different jobs and work well together. A camera shows the driver what is behind the truck, but the driver still has to notice, decide and brake. Search Eye applies the brakes itself. Many fleets run both.

Any commercial vehicle with air brakes. The most common are garbage and recycling trucks. It is also used on dump trucks, cement mixers, paving trucks, tack trucks, tankers, refuel trucks and utility trucks.

Search Eye is a one-time purchase with no subscription, and pricing depends on the setup and fleet size. One backing accident can cost a fleet tens of thousands of dollars once repairs, downtime, claims and insurance are added. Our ROI calculator shows the numbers for your fleet, and we send a quote on request.

Search Eye comes with a two-year warranty. Sensors typically last more than 10 years if they are not physically damaged.

The GS3000A uses three rear sensors and the GS4000A uses four. Larger trucks or bodies with wider rear blind spots usually need four. We help you pick the right model for each truck type in your fleet.

Six hours or less per truck. The first install always takes the longest. Once a technician knows the process, a three-sensor system usually takes about three to four hours. It does not affect other truck systems.

Your own mechanics, a Global partner in your region, or the body builder at the factory. Installation manuals are available in English, French and Spanish, and Global Academy has mechanic training.

Search Eye is an add-on that works with the truck’s existing air brakes. The kit includes the sensors, mounting boxes, in-cab control box, 75-foot wiring harness, junction box, brake valve and a sensor alignment tool. Your technician supplies vehicle-specific items like brake lines and some fittings.

Usually not. The infrared sensors are more sensitive to reflective materials, like safety vests and road signs, and to bright white objects with large surfaces. Those can be detected beyond 6 feet.

Use a measuring tape and a laser pointer to copy the path of the infrared beam. Global includes a laser alignment tool for this. The ideal target is 6 feet out and 25 inches high.

Check the underside of the truck with a flashlight first. The belly is exposed to rust, especially where roads are salted. Pick a protected spot with a solid mounting point, like a beam or frame wall. Some fabrication may be needed.

The system only turns on when the truck is in reverse with the ignition on. If it still does not light up, recheck the wiring in the junction box. The green and brown wires are the ones most often swapped.

Yes, for close work like backing to a dock or a container. The driver presses Auto Brake OFF. A red light and a pulsing tone stay on and the sensors keep warning. The system returns to automatic braking on its own.

A quick wipe of the sensor lenses as part of the driver’s daily inspection. The parts are built for dirt, weather and the harsh conditions garbage and construction trucks work in.
