摘要： A method of using a radar sensor 200 for a security system to determine a range for a sensed moving object or person, the method comprising: transmitting, from the radar sensor 200, a plurality of radar pulses and, when the object or person is present to reflect the radar pulses, receiving a corresponding plurality of pulses, the transmitting and receiving comprising: transmitting a first radar pulse having a first defined pulse duration; receiving a first reflected radar pulse, wherein the first reflected radar pulse is at least a portion of the first radar pulse that has reflected off of the object or person; determining, at the radar sensor 200, whether there is a first pulse overlap between the first radar pulse and the first reflected radar pulse; selecting a second defined pulse duration for a second radar pulse based on the determination of the first pulse overlap; transmitting the second radar pulse having the second pulse duration; receiving a second reflected radar pulse, wherein the second reflected radar pulse is at least a portion of the second radar pulse that has reflected off of the object or person; and determining, at the radar sensor 200, whether there is a second pulse overlap between the second radar pulse and the second reflected radar pulse; and determining a range in which the object or person is located based on the determinations of the first pulse overlap and the second pulse overlap.

摘要： A method of calibrating a sensor (200) for a security system, the method comprising: switching the sensor (200) to a zone calibration mode for configuring the sensor (200) to operate with a detection zone; detecting a moveable object (202) moving along a border of the detection zone, wherein the sensor (200) detects the position of the moveable object (202) as the moveable object (202) moves along the border of the detection zone; calculating zone calibration data for the detection zone based on the detected positions of the moveable object (202); and configuring the sensor (200) to operate using the calculated zone calibration data.

摘要： A presence sensor device 8 for a building is described. The presence sensor device 8 is for detecting persons and comprises a first radar sensor 14 and a second radar sensor 20. The first radar sensor 14 is arranged to operate with a first frequency band, a first power consumption, and a first range, with the second radar sensor 20 being arranged to operate with a second frequency band, a second power consumption, and a second range. The first frequency band is lower than the second frequency band and the first range is longer than the second range.
