DIY starter kits run $200 to $500 for equipment, mid-size systems $350 to $600, and professionally installed packages $600 to $1,500. Monitoring is separate: $0 to $10 a month self-monitored, $20 to $30 for standard professional monitoring, and $45 to $70 for premium plans from pro-install brands. SafeWise's 2026 tracking puts average equipment near $328 and average professional monitoring near $32 a month.

Add equipment, installation, activation and 36 months of monitoring. A no-contract DIY system at $400 equipment plus $23 a month lands near $1,230. A professionally installed system at $800 plus $50 a month lands near $2,600 — more than double, despite the second one often looking cheaper in an advert because the equipment is subsidised. Always compare the three-year figure, because that's the horizon over which the monthly fee overtakes everything else.

It depends on your household more than your budget. Professional monitoring earns its fee when nobody is home during the day, when you sleep heavily, or when you travel — someone is watching regardless of whether you see a notification. It's also usually required for an insurance discount and, in some jurisdictions, for police to respond at all. If someone is home most of the time and you're attentive to your phone, self-monitoring covers a lot for a fraction of the cost.

In many US cities and counties, yes — a monitored alarm has to be registered, typically for $25 to $100 a year. Some jurisdictions won't dispatch to an unregistered system, and some monitoring companies will register on your behalf. It takes five minutes to check your municipal website, and it's worth doing before installation rather than after the first activation.

The monitoring centre calls you first and asks for your passcode. Give it and nothing further happens. Miss the call and they request police dispatch. Most jurisdictions allow one or two free false alarms per year and then charge an escalating fee per call after that, commonly $50 to $400. The overwhelming majority of alarm activations are false, which is why these ordinances exist. Learn your system's disarm sequence properly and make sure everyone in the house — including guests and cleaners — knows it.

Verified response means police won't dispatch to a burglar alarm unless the activation is confirmed by video, audio, or an eyewitness. A number of US cities have adopted it to cut down on false-alarm call volume. If your area operates it, an alarm-only system may generate no police response at all, and cameras stop being a nice-to-have and become the thing that gets someone sent. Check your local police department's policy before choosing a plan — it's the single most consequential local detail in this purchase.

For evidence and awareness, yes. For prevention, partly — visible cameras deter opportunistic attempts, though determined intruders aren't much troubled by them. What cameras don't do on their own is summon anyone; there's no dispatch behind a camera unless you make the call. They pair best with an alarm rather than replacing one. Check whether recording needs a subscription, because a camera that only streams live is close to useless after the event.

DIY systems, generally yes — sensors are usually adhesive-mounted and the base station travels with you. Update the address with the monitoring company and re-register any municipal permit at the new address. Professionally installed and hardwired systems often stay with the property, and a contract may not transfer, which can mean an early termination fee. If you expect to move within the contract term, ask about the relocation policy in writing before signing, not after.

Usually a modest amount — commonly around 2 to 10% on the premium, depending on the insurer and what the system covers. Monitored fire and water detection sometimes earns more than burglary monitoring alone, since water damage claims are so common. You'll typically need a certificate from the monitoring company to claim it, and self-monitored systems rarely qualify. Ask your insurer what they'd credit before you choose a plan; occasionally it changes which tier makes sense.

How long is the term, what's the early termination fee, does the monthly price increase after a promotional period, who owns the equipment at the end, does it auto-renew and what's the cancellation window, and is the monitoring centre operated by the company or subcontracted. Get answers in writing. Long-term agreements aren't inherently bad, but an auto-renewing contract with a termination fee calculated on the remaining balance is the arrangement people most regret.

Start with every exterior door, then every ground-floor window that could be reached without a ladder, then a motion sensor covering the main interior path between likely entry points and the rest of the house. Upper-floor windows generally don't need sensors unless they're accessible from a roof, porch or tree. A glass break sensor covers a whole room and can be more economical than sensors on five windows in the same space. Beyond that, water and smoke sensors are usually better value than more entry sensors.

For modern wireless kits, yes — most take 30 to 60 minutes and involve peeling adhesive backing and following an app. The parts people get wrong are sensor alignment on doors that don't sit square, mounting cameras where the sun sits directly behind the subject at some point in the day, and skipping the range test on outbuildings. Professional installation makes more sense for wired systems, larger homes, and anywhere cameras need mains power run to them.
