A door access control method includes detecting whether a person is intending to pass through a door access control device. Then, it is identified whether a body temperature of the person near the door access control device exceeds a threshold value. The door access control device carries out an unlocking judgment procedure when the body temperature is below the threshold value. The unlocking judgment procedure is not carried out when the body temperature is not below the threshold value. Next, it is identified whether the person is qualified to pass through the door access control device based on the unlocking judgment. The door access control device remains in a locking state when the person is identified as not qualified to pass through the door access control device. The unlocking state is lifted when the person is identified as qualified to pass through the door access control device.

The present invention relates to a fire pre-detection device and, particularly, to a fire pre-detection device for pre-detecting a fire on the basis of the difference between a temperature of a thermal image acquired by a thermal imaging camera and a temperature of a differential thermal image, and finally detecting the fire by using a flame detector. The fire pre-detection device according to the present invention can pre-detect a fire sign or a fire through a thermal image and finally detect the fire through the flame detector, so as to pre-detect a fire and more clearly detect the occurrence of a fire.

A device including a sensor is disclosed. In one embodiment, the sensor includes a thermal infrared sensor or a sensor based on CMOS-SOI-MEMS technology (also referred to as “TMOS”). The sensor is capable of performing at least two functions at the same time. The first is remote temperature measurement and the second is presence detection. The sensor passively collects infrared information and a microprocessor coupled to the sensor determines the temperature as well as presence.
