Windsor Hills' 1970s-1990s stucco homes present unique installation challenges on the neighborhood's rolling terrain. Properties built in the 1970s lack pre-existing alarm wiring, while 1990s homes contain outdated phone line stubs that require bypassing.
Smart Shield Systems specializes in retrofitting these older homes with wireless security systems and properly angled cameras that account for the 6-10 foot elevation differences between rear neighbors. We install modern cellular communicators to replace dead phone connections and position perimeter cameras to avoid sky/ground angles caused by grade variations.
