PROBLEM TO BE SOLVED: To provide a security monitoring system capable of performing imaging as situation demands, without performing power-on and power-off each time the system is used, by once turning on a main power supply and operating vibration sensor means and timer means by utilizing an OR circuit or the like connected with the means thereafter.SOLUTION: A security monitoring system includes: power supply means; power supply control means; imaging means; video recording control means; video recording means; the vibration sensor means which outputs a signal when a vibration level is equal to or higher than a predetermined level; OFF-delay timer means which outputs a signal only within a predetermined setting time just after vibrations are not detected any more; and OR circuit means or the like which outputs a signal when either the signal from the vibration sensor means or the signal from the OFF-delay timer means is input.SELECTED DRAWING: Figure 10 |
