An inventive system and method for a buddy security system is presented. The system and method enable the buddy security system in which messages can be exchanged between two distinct security systems. The inventive system is operable on a network having dynamic IP addresses using a centralized database of real time IP addresses. An MSO maintains the centralized database including basic information for connecting the control panels of the security systems to each other. The first and second security systems each have a control panel having a dynamic IP address; the control panel of the second system provides information to and can be controlled by the control panel of the first system. The dynamically IP address of each control panel is obtained from the centralized database.
