Systems and methods for adjusting a broadcast pattern of an intrusion detector are provided. Such systems and methods can include a microwave sensor of the intrusion detector broadcasting a detection signal into a secured area in the broadcast pattern, a communication module of the intrusion detector wirelessly receiving a signal adjustment command from a remote device, and a processor and executable control software of the intrusion detector parsing the signal adjustment command and instructing a signal adjuster of the intrusion detector to adjust a sensitivity of the microwave sensor or an amplitude of the detection signal to alter the broadcast area of the broadcast pattern based on information contained in the adjustment command.
