Abstract

In a general aspect, a sensitivity setting is adjusted in a motion detection system. In some aspects, a user interface is provided by a motion detection system, and user input data is obtained through the user interface. A wireless communication link is identified based on the user input data; the wireless communication link is provided by a first wireless communication device and a second wireless communication device. Based on the user input data, a value is assigned to a sensitivity setting associated with the wireless communication link in the motion detection system. The motion detection system obtains data for motion detection based on wireless signals communicated through a space on the wireless communication link. Motion of an object in the space is detected based on the data and the value of the sensitivity setting.
