Abstract: A server accesses a security system profile of a first security system. The security system profile identifies a plurality of sensors connected to the first security system. The server identifies a second security system based on at least a first sensor of the plurality of sensors coupled to the first security system. The server then generates a notification sharing profile for the first security system based on the security system profile. The notification sharing profile indicates that the second security system corresponds to the first sensor. A first event triggered by the first sensor causes a first notification to the second security system.
