PreView Sentry coverage

PreView Sentry® radar is the most flexible and reliable radar available for heavy-duty vehicle and equipment industries. Sentry accurately detects objects in equipment blind zones and notifies the operator with both audible and visual alerts. These active alerts warn the the operator of potential collisions and allows them to take the appropriate action. Sentry is built tough to withstand the harshest working conditions imaginable, so it works everytime, all the time.

Heavy-duty industry accidents are costly.

Unfortunately, these accidents are on the rise. According to the Occupational Safety and Health Administration (OSHA), approximately 75% of struck-by fatalities involve heavy equipment.

PreView believes that this is unacceptable, and aims to significantly reduce the incidence and severity of heavy-duty equipment accidents by developing the most reliable safety solutions available to OEMs, upfitters and fleet operations.

PreView Sentry is the industry’s most flexible, accurate, and powerful active blind spot monitoring solution available. Sentry has a fully configurable detection zone, with the ability to detect objects from the face of the radar up to 30 meters, and the width of the detection zone is adjustable to fit almost all vehicle types. Sentry accurately identifies the location and velocity of up to 16 people or objects simultaneously and is designed to withstand the harsh environments encountered by heavy-duty equipment. With built-in fail safe alerts that notify the operator of radar blockage or communication issues, operators and fleet managers can be sure that they are working with the most reliable object detection system available.

EU Legislation

Regulation (EU) 2019/2144 amends Regulation (EU) 2018/858 and updates EU type-approval requirements to ensure the general safety of vehicles and the protection of vulnerable road users such as pedestrians and cyclists.
See also: Regulation (EU) 2018/858 — approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles. PreView’s engineering team spent over two years developing the PreView Sentry radar in order to provide our customers with the most sophisticated heavy-duty object detection radar available.
