Home security used to mean hiring ADT, signing a 3-year contract, and paying $50/month for a keypad by the front door. It's now one of the most fragmented purchases you'll make in your new home — with real tradeoffs between price, features, and whether someone will actually call the police when your alarm goes off.
The good news: you don't have to overspend to get genuine protection. A $20/month DIY system with professional monitoring from SimpliSafe or Cove protects your home just as well as a $60/month Vivint setup for the vast majority of homeowners. The differences only matter in specific cases — big houses, complex automation needs, or people who'd rather pay for installation than run it themselves.
This guide walks through how to think about the decision, the five systems worth considering in 2026, and the pricing traps the industry doesn't advertise.
Quick answer — what to buy
- Most new homeowners → SimpliSafe with professional monitoring. $250ish starter equipment, $30/month monitoring, self-install in an afternoon. Cancel anytime.
- Budget-conscious buyers → Cove. Same model as SimpliSafe but cheaper ($15-$28/month), simpler equipment, still professional monitoring.
- Big houses or people who want it installed → ADT or Vivint. Expect $50-$60/month and usually a contract, but professional installation and better smart home integration.
- Renters or first-time buyers → Ring Alarm. Works great with Amazon ecosystem, portable, no contract. Doorbell camera + simple alarm.
DIY vs professional monitoring
This is the first fork in the road, and it's less complicated than it sounds. Two questions: Are you willing to install the equipment yourself? And do you want someone to actually respond if your alarm goes off?
SimpliSafe, Cove, Ring, abode
You open the box, stick sensors on doors, plug in the hub. About 30-60 minutes of work for a typical home.
What you get
- Lower equipment costs ($200–$500 starter kits)
- No installation fees ($100+ saved)
- Easy to take with you if you move
- Most offer professional monitoring as an optional add-on
Downsides
- You handle setup and placement decisions
- Sensor range is usually 100-200ft from hub (big houses struggle)
- Cellular backup sometimes costs extra
Best for: Most homes under 3,500 sq ft with typical security needs.
ADT, Vivint, Brinks
A technician comes out, runs wires if needed, installs and tests everything. Usually 2-4 hours on-site.
What you get
- Professional placement of sensors and cameras
- Better smart home integration (especially Vivint)
- Commercial-grade equipment for larger homes
- One-call support for any issues
Downsides
- Installation fees of $99-$599
- Usually requires 3-5 year contract
- Early termination fees ($200-$1,500 depending)
- Harder to switch providers later
Best for: 4,000+ sq ft homes, heavy smart home integration, or buyers who'd rather pay for convenience.
What "professional monitoring" actually means
Regardless of DIY or pro install, professional monitoring means a 24/7 center watches your system. If your alarm triggers, they contact you — and if you don't respond or confirm it's a false alarm, they dispatch police or fire.
The alternative is "self-monitoring": you get a notification on your phone and have to call police yourself. It's free or cheap, but you're effectively on-call every hour of every day. For most people, the $15-$30/month for professional monitoring is worth it — especially when you're traveling, at work, or sleeping.
Compare top security systems
Six systems cover 90%+ of what most homeowners should consider. Here's how they stack up on the things that actually matter — monthly cost, contract terms, and what's included.
What it actually costs over 3 years
The number on the billboard is the monthly monitoring fee. What you actually spend is equipment + monitoring + fees, over whatever duration you stay with the provider. Here's a realistic 3-year cost comparison for a mid-size home:
| System | Equipment | Monthly (3 yr) | Install | 3-yr total |
|---|---|---|---|---|
| Cove | $200 | $720 ($20/mo) | $0 | ~$920 |
| Ring Alarm | $250 | $720 ($20/mo pro) | $0 | ~$970 |
| SimpliSafe | $300 | $1,080 ($30/mo) | $0 | ~$1,380 |
| Frontpoint | $250 | $1,620 ($45/mo) | $0 | ~$1,870 |
| ADT | $100 (rebated) | $1,800 ($50/mo) | $0 (promo) | ~$1,900 |
| Vivint | $700 (or financed) | $1,800 ($50/mo) | $0 (bundled) | ~$2,500 |
These numbers represent typical mid-tier packages. Your actual cost depends on how much equipment you need (more sensors and cameras = more money), which promotion you get, and whether you add any cameras or smart home components.
What you actually need
Starter packages from most providers include 4-8 sensors and a hub. That's usually enough for a small condo. For a typical single-family home, you'll want more. Here's a realistic shopping list for different home sizes:
Small home / apartment (under 1,500 sq ft)
- 1 hub / base station
- 2 entry sensors (front door, back door)
- 1-2 motion detectors
- 1 smoke/CO detector
- Optional: 1 video doorbell
Typical home (1,500–3,000 sq ft)
- 1 hub with cellular backup
- 4-6 entry sensors (all exterior doors + first-floor windows)
- 2-3 motion detectors
- Smoke/CO detectors on each floor
- 1 glass-break sensor (living room / main area)
- Optional: 1 video doorbell, 1 outdoor camera, 1 indoor camera
Larger home (3,000+ sq ft)
- 1 hub + range extender
- 8-12 entry sensors
- 4-5 motion detectors
- Multiple glass-break sensors
- Smart locks on exterior doors
- Multiple cameras (doorbell, outdoor flood, indoor)
- Consider pro install — DIY systems struggle past 3,500 sq ft
Research consistently shows that visible signs — yard signs, exterior cameras, video doorbells — deter most opportunistic burglars more effectively than invisible sensors. A $50 doorbell camera + $10 yard sign prevents more break-ins than $1,000 of hidden motion detectors. Budget accordingly: make it obvious you have a system.
7 traps to avoid when buying
Long contracts with high ETFs
ADT and Vivint typically lock you in for 36-60 months. Early termination can cost $500-$1,500 (remaining contract × monthly fee).
Prefer no-contract systems unless you're certain you'll stay 3+ years.
"Free" equipment tricks
$0 equipment usually means the cost is amortized into your monthly fee over the contract. Cancel early and you owe the equipment balance.
Ask what equipment costs outright. If the salesperson won't say, you know why.
Monitoring tiers that hide features
Cheapest monitoring plan often lacks cellular backup, smart home control, or even professional response. Basic = glorified loud alarm.
Confirm cellular backup and police dispatch are on the plan you're quoted.
False alarm fines
Many cities charge $50-$250 per false alarm after 1-2 freebies. If you have kids, pets, or a drafty house, false alarms happen.
Register your alarm with your city/county (usually required anyway). Some providers help cover the registration fee.
Camera storage add-ons
Your doorbell camera is worthless if you don't save the video. Most providers charge $3-$30/month for cloud storage on top of monitoring.
Ring Protect includes storage; SimpliSafe, Cove, Frontpoint charge extra. Factor into total cost.
Contract auto-renewal
Traditional contracts (ADT, Vivint) often auto-renew for 1-2 more years if you don't cancel within a specific window (usually 30-60 days before contract end).
Calendar reminder 3 months before contract end so you can evaluate before auto-renew kicks in.
Moving fees
Some pro-install systems charge $100-$300 to "transfer" service when you move. DIY systems take 10 minutes to relocate for free.
Expecting to move in 2-3 years? DIY saves real money and hassle.
Installation and setup timing
DIY systems (SimpliSafe, Cove, Ring, Frontpoint)
Order during move-in week. Equipment typically arrives in 2-4 business days. Setup time: 30-60 minutes for most homes. Sensors are peel-and-stick — no drilling or wiring. Professional monitoring activates as soon as you complete the setup in the app.
Professional install (ADT, Vivint)
Schedule during your move-in week but expect 5-10 day lead time for the technician appointment. Installation takes 2-4 hours. They'll test all sensors, walk you through the panel, and set up the app. Monitoring activates same day.
Many cities require you to register your alarm system with the police department (often a small one-time fee, $10-$50). Unregistered alarms result in either no police response or heavy false-alarm fines. Do this before you arm the system the first time.
What about when you travel?
Every modern system lets you arm/disarm remotely via app. Some DIY systems offer "scene" modes — set to "Away" when traveling, and the system uses motion sensors more aggressively. Tell your monitoring company you're traveling so they can escalate faster if anything trips.
Frequently asked questions
Do I really need professional monitoring, or is self-monitoring enough?
Self-monitoring works if you're comfortable being on-call 24/7 for your own alarms. The reality is most people ignore phone notifications during meetings, while sleeping, or when the phone is on silent. Professional monitoring ($15-$30/month) ensures someone responds even when you can't. For the cost, it's usually worth it — especially for a new homeowner settling into a place you don't yet know well.
How do I cancel a home security contract early?
Read your contract's ETF clause first. Most long-term contracts charge the remainder of the contract × monthly fee, sometimes with a discount (75% is common). For moving, some companies waive ETFs if you take the service with you or sell your home to a new customer. Negotiate — retention departments often offer concessions to keep you from switching.
Does home security actually reduce insurance?
Yes, typically 5-20% off your homeowners insurance for a monitored system with central station response. Ask your insurance agent what counts — some require specific certifications (like UL-listed monitoring) or specific equipment to qualify for the discount. This can offset $5-$20/month of your monitoring cost.
What happens if my internet goes out?
Depends on the system. Quality systems have cellular backup built in — if Wi-Fi dies, the hub uses a cellular connection to reach the monitoring center. Budget plans sometimes charge extra for this. If your system only works over Wi-Fi and your internet goes out, the alarm still sounds locally but no one's being notified. Always confirm cellular backup is included in the plan you choose.
Can I keep my existing ADT system if I'm buying a house with one already installed?
Sometimes. ADT and similar providers will "take over" existing equipment — you sign a new monitoring contract and they activate the system. But you'll inherit the contract terms. Alternative: a company like SimpliSafe can replace the hub with their own (keeping existing sensors in some cases), letting you switch providers without buying all new equipment.
Do burglars really get deterred by security systems?
Yes — studies (University of North Carolina, among others) interviewing convicted burglars consistently show that visible signs of security are the #1 deterrent. They'll often skip to the next house on the block that looks easier. Even the yard sign alone (without a real system) reduces break-in risk measurably. Invest in visible deterrents: cameras, signs, doorbell cameras, motion-activated lights.
Can I use my old phones as security cameras?
Yes, with apps like Alfred or Manything. A free way to add cameras to your system. Not as feature-rich as purpose-built cameras (no motion zones, weather-resistance, or integration with your alarm), but good for monitoring a specific area — baby's room, backyard, etc.
What's the best system for renters?
Ring Alarm, SimpliSafe, or Cove — all DIY, all portable, all no-contract. You can take them to your next place easily. Sensors are peel-and-stick, so no drilling or damage to walls. When you move, the system moves with you and monitoring picks right up at the new address.
