Direct answer
Professional monitoring is better for owners who want staffed receipt of eligible alarm signals and a defined notification or dispatch procedure when they are unavailable. Self-monitoring sends alerts directly and may avoid a monitoring fee, but it depends on the owner noticing the event, having connectivity, interpreting it correctly, and taking action.
Neither option prevents entry by itself. Locks, openings, lighting, detection, cameras, and household procedures still matter. Review response rules, verification, cellular backup, contract terms, municipal permits, and false-alarm policy before activation. Life-safety devices require particular care and should comply with code and manufacturer instructions; they are not ordinary convenience sensors. Ask who receives each signal, what happens if contacts do not answer, and which functions continue during internet or power failure.
