Smart home security integration in San Diego County. One platform for alarm, cameras, and automation. Call (844) 477-7627.

Established suburban single-family (1960s–1980s), stucco and wood siding, 1,200–2,400 sq ft. Dense 40–60 year mature tree canopy blocks standard camera angles—elevated pole-mount or gutter-line cameras with infrared needed; 1960s homes have no alarm wiring; I-8 noise can interfere with glass-break sensors.

Fletcher Hills' 1960s-1980s suburban homes present unique security challenges with their original construction lacking pre-wired alarm systems and mature tree canopies blocking standard camera sight lines. The stucco and wood siding construction requires specialized mounting techniques for optimal sensor placement.
Smart Shield Systems addresses these specific issues by installing elevated pole-mount cameras that clear the 40-60 year tree coverage and running new alarm wiring through the older home structures. We use infrared-equipped cameras for the dense foliage conditions and calibrate glass-break sensors to filter out I-8 freeway interference.
