Mountain View's suburban homes from the 1970s-1990s present unique installation challenges due to their stucco construction and mixed security infrastructure. While 1970s properties lack any alarm wiring, 1990s homes often contain outdated phone-line connections that require complete system overhauls.
Smart Shield Systems specializes in retrofitting these 1,200-2,200 sq ft homes with modern wireless security networks that bypass obsolete phone lines. Our technicians handle everything from drilling through stucco walls for sensor placement to converting old alarm stubs into cellular-based monitoring systems.
