PROBLEM TO BE SOLVED: To provide a security system and a security device capable of changing a security state safely and surely based on a request from a user. SOLUTION: A change request signal for a security state is transmitted form a portable terminal 30 to this security device 10. On receiving the change request signal, the security device 10 transmits a countermeasures request signal to a monitoring center 40 and outputs a unlocking permission signal to a security facility device 17. When a security guard unlocks the security facility device 17, enters a monitoring object, and changes a security state of the monitoring object after checking the inside, the security device 10 transmits a countermeasure request cancel signal to the monitoring center 40 and stops transmission of the unlocking permission signal to the security facility device 17. In this way, change request processing is finished. The security device 10 finishes the change request processing in a similar manner when it receives a request cancel signal from the portable terminal 30. COPYRIGHT: (C)2006,JPO&NCIPI
