Smart Lighting


Precise sensing—say goodbye to “ineffective lighting.” At the heart of radar’s application in lighting is intelligent interconnection: by sensing the movement of people and objects, the lighting system achieves automated control—lights turn on when someone enters the room and turn off when the person leaves. Essentially, this endows lighting with a “sensing brain.”

Smart Security


At the heart of radar’s application in camera-based security systems lies “precise triggering and range-based alerting.” It endows cameras with “long-distance sensing capabilities,” addressing the pain points of traditional cameras—such as “blind-spot imaging” and “post-event retrospective analysis”—and enabling proactive security through “preemptive warnings and precise capture during events.”

Smart Home Appliances


By using radar to detect the presence, distance, movement trajectories, and even subtle movements (such as breathing) of humans or objects, home appliances can “understand” the environmental conditions. For example, an air conditioner can sense prolonged absence of occupants and automatically reduce power consumption or shut down; a refrigerator can recognize when a user approaches and automatically light up the screen; and a range hood can be activated with a wave of the hand and adjust its fan speed accordingly. These features not only enhance the interaction experience but also make appliances more energy-efficient.

Smart Home


Without requiring image capture, radar can precisely detect the presence, location, and movements of people—and even subtle vital signs such as breathing and heart rate—while safeguarding privacy and penetrating non-metallic obstructions. It enables automated control that ensures devices start up when a person enters the room and automatically enter energy-saving mode when the person leaves. Additionally, it supports natural interactions like gesture-based controls and offers enhanced safety through features such as fall detection and alerts for unusual intrusions. Ultimately, this technology makes home environments more convenient, comfortable, secure, and low-carbon.

Automotive ADAS


In smart vehicle applications, radar serves as the “eyes” for environmental perception. By precisely detecting the position, speed, distance, and motion trajectories of surrounding objects—such as vehicles, pedestrians, and obstacles—it provides critical data support for autonomous driving decision-making and driving safety.
