<P>PROBLEM TO BE SOLVED: To provide a security device with an entry and exit timer function capable of performing switching operation of a security state at own comfortable pace, without being conscious of entry and exit timer time. <P>SOLUTION: The security device includes: a security switching part 20 which is installed in a building and performs operation for setting a start of security; a sensor 2 for detecting opening and closing of a door of the building or presence of a person and outputting a detection signal; a timer part 30 for starting timing of predetermined time at the same time as the security start operation is performed; an alarm output part 50 which cancels the detection signal output from the sensor until the timing of the predetermined time is finished, and when the detection signal is output from the sensor after the timing of the predetermined time is finished, which determines that the detection signal is valid and outputs the alarm; a storage part 70 for storing a unique identifier and an electric wave intensity threshold value of a mobile terminal possessed by a user; and an electric wave receiving part 40 for measuring electric wave intensity of electric waves. The timer part 30 stops the timing of the predetermined time when the electric wave exceeds the electric wave intensity threshold value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
