It's the most common question we hear, and the honest answer is: it depends on your home, your neighborhood, and your peace of mind. This guide walks you through the factors that actually matter — then hands you a quick quiz to settle it.

Signs you probably do

A security system is likely worth it if several of these apply to you:

  • Your home sits empty for predictable stretches (work, travel, long commutes).
  • There have been break-ins, car burglaries, or package thefts nearby — see our 7 signs guide.
  • You have entry points out of street view — a back door, side gate, or ground-floor window.
  • You live alone, have kids or elderly family, or simply don't feel at ease at home.
  • Your only current protection is locks.

What you actually get for the money

A modern system does four things a lock can't: deter (visible cameras change a burglar's calculation), alert (you know instantly), record (evidence and insurance), and respond (monitoring dispatches help). Many U.S. insurers also discount premiums for a monitored system, offsetting the monthly cost. For a full cost picture, see our 2026 cost guide.
