“AT&T Home Security System - Component Images”

Summary: AT&T designed & manufactured a home security system in the early 1990's. Their home security system was sold through independent home security system companies. AT&T withdrew from the home security system market only after a few years. AT&T home security system components featured a robust design and excellent quality control.
