REMOTE SECURITY MONITORING METHOD

PROBLEM TO BE SOLVED: To quickly locate, at a security monitoring center without the need of using a private communication channel, a security monitoring device where security monitoring information is generated from among a large number of such devices for customers joining the above center which are installed far away from the center. SOLUTION: A security monitoring center A and many security monitoring devices Bi for customers are respectively connected through an ISDN communication channel network M. The above arrangement, if security monitoring information Fi is generated in anyone of the security monitoring device Bi for the customers, the information is automatically sent out to the security monitoring center A through the ISDN communication channel network M along with attribute information (subscriber number) Ni. In the security monitoring center A, the sent-out security monitoring information Fi and the attribute information Ni are received, thus it is possible to locate/monitor any security monitoring device which has generated the security monitoring information from among a large number of such devices Bi for the customers.
