Our 4D radar imaging sensors can see through walls and objects and track and map everything happening in an environment in real time.

Vayyar sensors generate rich point cloud data, enabling devices to instantly recognize and respond to their surroundings, while an ultra-wide field of view ensures maximum horizontal and vertical coverage. Because 4D imaging radar sensors do not rely on cameras or optics, they are robust in all lighting and weather conditions, do not rely on line-of-sight and maintain privacy at all times.

Vayyar’s mission is to continue delivering the next generation of sensing technology that is miniature, affordable and versatile enough to make a genuine difference to everyone’s lives.
