A security system using a security detector associated with a personal computer attached to an existing data transmission network, where the personal computer is effective to detect security breaches and transmit an alarm even if the personal computer is not in its operating mode. When a security breach is detected by the security detector, the data transmission network is used to report the incident to a monitoring station for appropriate logging and action. Because the security system is coupled to a data transmission network and computer resources, the security system can be remotely activated and can respond to historical sensing of a security detector to adjust its threshold.
