RearSentry Fleet Vehicle Object Detection by Rostra

RearSentry is an economical accessory for industrial and commercial vehicles that uses sophisticated microwave technology to alert drivers of objects up to 12 feet behind the vehicle. A RearSentry system eliminates hazardous blind spots and allows for safer and easier vehicle reversing. Use RearSentry on: Utility Vehicles, Box Vans, Commercial Vehicles, Delivery Trucks, and other industrial and commercial vehicles Class 2-8.

A small investment in a RearSentry can prevent costly damage from common accidents. Thousands of potential repair and legal bills can be avoided, and the ease of using RearSentry will allow drivers to save money in another way - by reducing vehicle downtime and enabling them to return to the road quicker to continue their days' work.

When the vehicle is moving in reverse and an obstruction is detected in the sensor's coverage area, the sensor determines the distance to the obstacle. This information is then instantaneously converted into a tricolor display and an audible alert. The RearSentry™ is not affected by adverse weather conditions such as extreme heat or cold, rain, sleet, snow, hail, mist or fog.

Product Features


The RearSentry vehicle reversing system is designed to alert drivers to objects at the rear of the vehicle as far away as twelve feet away. This includes objects beyond the vehicle's corners.

Reduce Costly Repairs

With the ability to detect unseen objects, a RearSentry reversing system helps to save on costly cosmetic repairs and could reduce insurance and legal claims.

Reduce Maintenance

With their ability to ”see through“ mud, snow or glaring sun, the RearSentry sensors make sure you have more time to pay attention to what is most important.

Automatic Reset

Once you have safely maneuvered your vehicle around any detected obstacles, the RearSentry will automatically reset itself to begin looking for other objects that might be in your way.

According to a recent survey, 27% of all vehicle accidents, one every 90 seconds, occur while the vehicle is in reverse. Having a RearSentry is like having an extra set of eyes to help protect your property and to prevent injury, an added measure of safety and security.

Drivers of commercial equipment, private delivery vehicles, or box vans face many challenges while backing up. A RearSentry is a cost-effective, state-of-the-art accessory that can help all drivers "see" behind their vehicle. It works in all weather conditions and at night; a distinct advantage when drivers are returning their vehicle to a loading dock.
