What range do I actually need?

Most dedicated parent-unit monitors advertise 900–1,000 ft of line-of-sight range, but verified-purchase reviewers consistently note that walls, floors, and other 2.4 GHz devices cut that significantly. For a typical 2–3 bedroom home, the long-range claims hold up; for larger houses or yard use, reviewers recommend stepping up to a model with a stronger antenna or a Wi-Fi monitor that piggybacks on your home network.
