Currently, other brands of smart cameras already support dynamic object detection function but rely on vision to achieve. Amazon's technology is similar to ultrasonic radar, which can roughly determine whether there are objects nearby. In addition, Google also uses ultrasound to detect the distance between people and products in the Nest smart display and the Nest mini speaker.
