A local area security system interfaces with one or more vehicles to provide enhanced security. The vehicles have vehicle sensors which may further help determine a presence of potential threat within a vicinity of the local area security system. The multiple vehicle network may communicate with each other to expand the vicinity of the local area security system, share equipment, computing resources, and information in the determination of the presence of the potential threat. The battery powered vehicle may employ various methods to conserve battery power while coupled to the local area security system.
