Smart lock installation in San Diego County. Keyless entry, app control, alarm integration. Free consultation. Call (844) 477-7627.

Master-planned suburban single-family (1985–2005), stucco with tile, 1,600–3,000 sq ft. Coyote Creek and Sweetwater River open space corridors cause wildlife intrusion—raccoons, coyotes, rabbits trigger motion and cameras nightly; obsolete phone alarm stubs still light up keypads so homeowners assume monitoring works; AI person-only detection is essential.

Rancho San Diego's master-planned homes from 1985–2005 feature stucco construction with tile roofs, creating unique installation challenges for security systems. The 1,600–3,000 sq ft single-family layouts require strategic sensor placement to avoid false alarms from wildlife near Coyote Creek and Sweetwater River corridors.
Smart Shield Systems specializes in upgrading obsolete phone-line alarm systems still found in these homes, installing AI person-only detection cameras that distinguish between coyotes, raccoons, and actual intruders. We retrofit existing stucco walls with wireless sensors and replace non-functional monitoring connections that leave keypads lit but unmonitored.
