Frequently asked questions

Can you use a home security system without a subscription?

Yes. Every system here self-monitors for free: you install the sensors, and your phone gets an instant alert when one trips, with full app control to arm, disarm and sound the siren. What a subscription adds is professional dispatch — a staffed center that answers the alarm for you. The alarm itself works with no monthly fee.

Which security system is truly free to run?

eufy is the purest no-fee pick: it's self-monitored by design and has no professional-monitoring option at all, so there's nothing to subscribe to. SimpliSafe, Ring Alarm and Abode also self-monitor for free, but they keep professional monitoring available as an optional, month-to-month add-on if you ever want it.

What do you lose by self-monitoring instead of paying for a plan?

You lose professional dispatch — the 24/7 staffed center that answers the alarm and can call police or fire on your behalf when you're asleep or away. With self-monitoring you're the one who reacts to the phone alert. For many households that's enough; if you travel often or want around-the-clock coverage, keep optional monitoring within reach.

Does a no-subscription system still work with cameras?

The alarm does, for free — but recorded camera footage is often the piece that carries a separate fee, even when the alarm itself is free to self-monitor. If you plan to add cameras, check each brand's camera plan and price it separately. For cameras that record locally with no fee, see our camera picks.
