SECURITY SYSTEM USING CALL DISPLAY |
摘要 |
An improved alarm security system is disclosed which provides caller identification information when an alarm panel completes a telephone communication with a central computer. Such information is automatically provided by the telephone network upon initiation of a telephone communication. The central computer can use this information alone or in combination with other information received from the alarm panel to improve reliability and provide a more effective security system.
