Mix of small single-family, duplexes, and older apartments (1940s–1960s) adjacent to auto dealership row and commercial corridor. Residential cameras must filter out constant 24/7 commercial motion; shared-wall duplexes need independent alarm zones; I-5 proximity enables drive-through crime.

National City Mile of Cars / Westside features 1940s-1960s single-family homes, duplexes, and older apartments with original electrical systems and shared walls. The proximity to auto dealerships and I-5 creates constant commercial traffic that triggers false alarms, while duplex units require separate security zones.
Smart Shield Systems installs motion detectors with commercial filtering technology to eliminate dealership activity false positives. We wire independent alarm systems for each duplex unit using existing electrical pathways and install reinforced door sensors on original 1940s hardware.
