Percentage Security Installations Include Interactive Capability – Interactivity was close to unknown 10 years ago. When interactivity did occur, it was for custom security systems only. And the capability today is not only for installed systems; it is available in most DIY systems, even low-cost systems.

Some innovations are simply “nice-to-have”; others are compelling and will enter mainstream consumer wants quickly. Parks Associates believes voice recognition is next on that list.
