<P>PROBLEM TO BE SOLVED: To provide a security system capable of securely preventing its erroneous operation due to external noise. <P>SOLUTION: This security system has a certifying part 2 for determining whether certification for a signal for certification taken in from a certification signal receiving part 1 is satisfied or not, a lock control part 4 for controlling driving of an actuator of a lock device 3, and a noise determining part 5 for determining the presence or absence of undesirable external noise. The condition for preventing the determination that the noise is present from the noise determining part 5 from being outputted is the prerequisite for outputting an unlocking signal to the lock device in the lock control part 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
