Security system using sequence signal |
摘要 |
There is provided an inexpensive and easy-to-use security system whose setting can be changed freely by a user using a target to be managed by the security system and whose presence is not easily perceived by an intruder. The security system comprises security targets and a management system which manages the security targets. The security target comprises a plurality of activation switches which generate activation signals and a plurality of partial signal generating sections that generate partial signals which can constitute a predetermined sequence signal upon receipt of activation signals generated from the activation switches, in accordance with predetermined relationships with these activation switches. The management system compares partial signals generated from the partial signal generating sections with predetermined sequence information and gives an alarm when they do not match each other. The relationships between the activation switches and the partial signal generating sections can be changed freely by a user of the security target.
