Best Smart Home Security Systems 2026: SimpliSafe vs ADT vs Ring Alarm vs Vivint vs Abode

Buying a home security system seems simple. Then you read the fine print. One brand flashes a low monthly price, another wants you locked into a three-year contract, and a third charges extra just so you can keep your own camera clips. Those little add-ons stack up faster than you’d think.

I’ve lined up five names (SimpliSafe, ADT, Ring Alarm, Vivint and Abode) and compared them on installation, monitoring costs, contracts and cameras. SimpliSafe and ADT get the most detail. For the other three, I’ll tell you what to check instead of guessing at prices, because guessing on prices is how people end up annoyed later. I’ve also thrown in a few setup details people tend to forget until the system’s already stuck to the wall.

Quick answer: For most people, especially renters and anyone who hates contracts, I’d go with SimpliSafe. It’s DIY, billed monthly with no contracts, and plans run from $9.99/mo (self-monitoring) up to $79.99/mo, with a 60-day money-back guarantee. Want a technician to install everything? ADT’s the better fit, but professional installation comes with a 36-month contract (24 months in California). I couldn’t verify current pricing for Ring Alarm, Vivint or Abode, so check their official pages before you decide.

SimpliSafe vs ADT vs Ring, Vivint and Abode at a glance

Every number in this table comes from the brands’ own pricing and support pages. Where it says “Not confirmed,” I couldn’t find it there, and I’d rather leave a gap than make something up.

All prices come from official vendor pages. They change a lot, so check the brand’s site before you buy.

The best smart home security systems, ranked by what I could confirm

I ranked these by how much I could actually verify, not by how famous the brand is. Ring, Vivint or Abode might turn out to be a great fit for your place. I just won’t recommend one on guesswork.

1. SimpliSafe

SimpliSafe is where I’d send most people first. Plans are billed monthly with, as SimpliSafe puts it, “no contracts or hidden fees,” and you can cancel whenever you like. Installation’s DIY too. No technician visit to schedule, and no stranger drilling holes on their timetable instead of yours.

SimpliSafe lists five residential plans on its official service plan page. Seen an older plan called Fast Protect floating around? That’s Core now. SimpliSafe says Core and Standard are both free for the first month.

These are the prices SimpliSafe’s official plan page showed when I wrote this. They do change, so recheck before you buy.

Moving up the tiers is mostly about cameras and extras. Standard is the cheapest way into professional monitoring, but it won’t save camera recordings. Self-Monitoring flips that. You get the recordings but no monitoring center, so every alert lands on your phone and dealing with it is on you.

Pro and Pro Plus add Active Guard Outdoor Protection (SimpliSafe used to call this “24/7 live guard protection”). On Pro it runs overnight in your local time. On Pro Plus it runs around the clock. Two catches, though: you need the Outdoor Camera (Series 2), and you have to opt in. SimpliSafe also says video verification and intruder intervention only come with some professional plans, so make sure yours actually has them before you pay top-tier money.

A couple more points in SimpliSafe’s favour. There’s a 60-day money-back guarantee, and paying for professional monitoring gets you a lifetime equipment warranty. Nice. I couldn’t confirm current hardware package prices, though, so check those on SimpliSafe’s site.

2. ADT

ADT is really two products wearing one name. ADT Blu is the DIY side, with no long-term contract, so you can cancel or switch anytime. Then there’s the classic professional installation. That one comes with a contract you really need to read.

Here’s the ADT Blu pricing, straight from ADT’s Blu monitoring page:

These were the prices on ADT’s official pages when I wrote this. ADT’s own pages don’t agree on Pro-Protect, so confirm it at checkout.

That Pro-Protect mismatch bugs me a bit. ADT’s starter kit page lists it at $24.99/mo, with a free first month if you activate within 30 days. The Blu monitoring page says $34.99/mo. So which is right? Go with whatever shows up in your cart, because that’s the number you’ll actually pay.

Hardware is much clearer. The ADT Blu Security Starter Kit is $249, and in the box you get three door/window sensors, one motion sensor, a base, a yard sign and window stickers. It needs Wi-Fi on 2.4 or 5 GHz (those are the two usual bands your router puts out). ADT’s products page also lists the ADT Base package at $269. Cameras? That’s an extra $10/month, according to ADT.

Professional installation is a whole different deal. You’re signing a 36-month monitoring contract, or 24 months if you live in California, and there are installation fees on top. Starting prices aren’t consistent across adt.com, so I’m not going to throw a number out. Get a quote for the exact package you want.

If your house is already full of Google Nest gear, there’s one ADT feature worth knowing about. Trusted Neighbor needs the ADT Complete plan (Nest Aware is included), Google familiar face detection, the ADT Base, and a compatible smart lock and camera. That’s a lot of pieces. It really only makes sense if you already own some of them.

3. Ring Alarm

Already using Ring devices? Then Ring Alarm is the obvious one to look at. The catch: I couldn’t confirm Ring’s current plan names or prices before publishing. You’ll probably see both Ring Home and Ring Protect mentioned for its tiers, so check which name is current on ring.com/plans.

While you’re on that page, confirm what professional monitoring costs per month, what the self-monitoring tier actually includes, and the specs on the Alarm Pro base station. I think the Alarm Pro has a built-in eero Wi-Fi 6 router, but I haven’t verified that on Ring’s site. Treat it as unconfirmed.

4. Vivint

Vivint is the one I can say the least about from official sources right now. I couldn’t confirm whether professional installation is required, what the contract or financing terms look like, or what monitoring costs. That’s three big gaps.

Before you sign anything, put those three questions to Vivint directly, on vivint.com or during a sales call. If the answer includes a multi-year agreement or equipment financing, add up the total for the whole term and compare it with SimpliSafe or ADT Blu. A bit of maths, but worth it.

5. Abode

Abode is another DIY-friendly name that comes up a lot. But I couldn’t verify its current plan names, its prices, or which kits it’s selling right now (older guides talk about the Iota). So head to goabode.com, look at the current plans page and kit list, and then compare it with the rest.

DIY vs professional installation

With DIY, you unbox the kit, stick the sensors on your doors and windows, set up the base and pair everything with an app. Professional installation? A technician does all that for you.

Going by what I could confirm, the real difference isn’t the work. It’s the commitment. SimpliSafe and ADT Blu let you set things up yourself with no long-term contract, while ADT’s professional installation drags installation fees and a 36-month contract along with it. If you rent or move a lot (or just like being able to walk away), DIY is the safer bet. If drilling and pairing devices sounds like a weekend you’ll never get back, pro install might be worth the contract. Just know what you’re signing.

How much professional monitoring costs, and do you need it?

With professional monitoring, a monitoring center picks up your alarm signals and can get help sent out. With self-monitoring, the alerts hit your phone and what happens next is up to you.

That’s a bigger deal than it sounds. ADT says it plainly: without professional monitoring, it can’t contact first responders for you. So if you travel a lot, sleep through phone notifications, or just want someone else watching when you can’t, I’d pay for monitoring.

On price, SimpliSafe’s monitored plans start at $22.99/mo (Standard) and top out at $79.99/mo (Pro Plus). ADT’s DIY Pro-Protect plan shows up as $24.99 or $34.99/mo, depending on which ADT page you land on. Professionally installed ADT pricing varies by package. And if you’re happy handling alerts yourself, both brands have self-monitoring options somewhere in the $9.99 to $14.99 range.

Contracts and cancellation fees

This is where people get burned. SimpliSafe bills monthly. No contracts, cancel any time. ADT Blu doesn’t have a long-term contract either.

ADT’s professional installation is the odd one out. It’s 36 months (24 in California), and ADT may charge 75% of the remaining monthly charges if you cancel early. Ouch. I couldn’t confirm contract terms for Ring, Vivint or Abode, so ask before you hand over a cent.

Cameras: built in, add-on or separate?

Cameras are where your monthly bill quietly creeps up. On SimpliSafe, Standard doesn’t include camera recordings, and Active Guard on Pro and Pro Plus needs the Outdoor Camera (Series 2). On ADT, adding cameras is an extra $10/month, and Video Connect is a $9.99/mo plan that’s cameras only.

Worth pausing here, though. Is all you really want a look at who’s at the door or in the driveway? Then you might not need a full alarm system at all. I put together a list of the best home security cameras with no monthly fee in case you’d rather skip the subscription entirely.

Don’t forget Wi-Fi and account security

Your smart security system is only as reliable as your Wi-Fi. ADT’s Blu Starter Kit needs Wi-Fi on 2.4 or 5 GHz, and any cameras you add will lean on your network too. If your router can barely reach the garage or the back door, work out whether mesh Wi-Fi or a regular router suits your home better before you start blaming the alarm.

Then there’s the account. That app controls your alarm, and maybe your cameras and locks too. Use a strong, unique password and turn on two-factor authentication if the app offers it. And please don’t share one login with the whole house. A good password manager makes all of this pretty painless, and I’ve got my picks for the best password managers for families if you need one.

SimpliSafe or ADT: picking the right fit

If flexibility matters to you, start with SimpliSafe. It’s DIY, there’s no contract, and the money-back guarantee gives you room to change your mind. Core is the plan I’d look at first, since it adds network backup without pushing you into the pricier tiers.

Rather have someone else do the install? ADT is the option I could actually confirm here. Just go in knowing about the 36-month contract and that early cancellation charge. And if Ring Alarm, Vivint or Abode catches your eye, hit their official pricing pages first. Prices on all of these move around a lot, so check the number on the brand’s site the day you buy.

Frequently Asked Questions
