PreView® Radar Systems from Sensata is an Advanced Driver-Assistance System (ADAS) – a rugged and reliable object detection technology that assists with protecting people and property.
PreView Side Defender®II Radar System, the industry’s most advanced side collision avoidance solution, has been developed specifically for over-the-road truck operators and city service and delivery drivers. 
According to independent research, the incidence of highway and urban collisions are rising by almost 10% per year. PRECO believes that this is unacceptable and we are driven to design technology that assists heavy duty vehicle operators to mitigate these avoidable accidents.
The Side Defender®II system actively warns operators with audible and visual alerts, in order for them to take the appropriate actions to mitigate collisions. Additionally, it has the ability to integrate with telematics applications, vehicle control systems, vision systems or other sensors using industry standard communications.
As part of the Side Defender®II system, the PreView® v2 in-cab display equips operators with more intuitive audible and visual alerts while offering installers more flexibility and time savings. For retrofit applications, the new display can provide a GPS based vehicle speed message, while OEMs and bodybuilders can connect the display directly to the vehicle CAN-bus for vehicle speed information.
