The present disclosure relates to methods, systems, and apparatuses for dynamically linking a first security system and a second security system. A method may include selectively linking a first security system and a second security system based on one or more link conditions. The method may further include receiving one or more first sensor event messages from the first security system and sending at least a portion of the one or more first sensor event messages to the second security system. The method may also include receiving one or more second sensor event messages from the second security system, and sending at least a portion of the one or more second sensor event messages to the first security system. In one aspect, the method may include selectively de-linking the first security system and the second security system based on one or more de-link conditions.
