Methods, systems, and apparatus, for an infrared detector are provided. In one aspect, an infrared detector is provided that includes a pyroelectric sensor; a controller for receiving a trigger signal outputted by the pyroelectric sensor; a thermopile sensor, wherein the controller starts the thermopile sensor after receiving the trigger signal output by the pyroelectric sensor; and an alarm, wherein the controller controls the alarm to generate an alarm signal in response to a determination that a difference between a current temperature and a background temperature detected by the thermopile sensor is larger than a threshold value and a determination that the areas of the thermopile sensor activated correspond to a human being.
