Compare ADT and SimpliSafe

ADT is a long-time home security favorite with over 130 years of experience. Meanwhile, SimpliSafe is a newer DIY security provider that made its mark in the security space in 2006. Lately, both providers have been popular picks for home security shoppers, but there are a few big differences.

ADT offers more traditional home security with a contract, professional monitoring and installation. And even though ADT requires a contract, you’ll have a 6-month money-back guarantee and a $500 Theft Protection Guarantee to cover $500 of your insurance deductible if a break-in happens and your system is armed.

On the other hand, SimpliSafe offers more flexibility without long-term contracts and the choice between DIY or professional services. You’ll have a shorter risk-free return period, but you’ll be able to expand your system without expensive package upgrade charges. It all comes down to what works best for you.

Safety Score Breakdown

We use our very own Safety Score to evaluate the top home security factors that help keep you safe and, most importantly, make you feel safe each night. We looked closely at ADT and SimpliSafe to highlight each provider’s critical differences.

SimpliSafe and ADT both offer great preventative features, including mobile alerts and surveillance features to help keep you safe and informed the moment the unexpected happens. But ADT has fewer control features than SimpliSafe, lacking flexibility in monitoring and installation services that would give you more control of your system. Fortunately, both providers have high reliability and response scores with award-winning 24/7 professional monitoring, durable equipment, and high customer satisfaction ratings. Here’s a breakdown of both providers for a closer comparison.

  • Equipment

    Tie: ADT and Simplisafe

    Both ADT and SimpliSafe offer a variety of home security products to choose from. Both offer environmental monitoring products, including smoke detectors and carbon monoxide detectors. You’ll also be able to choose from their in-house smart home products, including video doorbells and smart locks. But there’s one big difference — ADT offers both indoor and outdoor cameras, while SimpliSafe’s SimpliCam doubles as an indoor and outdoor camera. It all boils to what equipment and features give you peace of mind and safety.

  • Cost

    Winner: SimpliSafe

    There’s a big difference between ADT and SimpliSafe when it comes to price. ADT lets you pay for your equipment throughout your contract, while SimpliSafe requires you to purchase your equipment upfront. ADT requires at least $599 worth of equipment for service, and professional monitoring starts at $57.99 per month. Meanwhile, SimpliSafe lets you get a system that fits your budget. Their packages start at $183 and you can add equipment to upgrade anytime. Despite the fact that you have to pay for it upfront, SimpliSafe’s equipment is much cheaper, starting at only $14.99 per month. Even if you’ll be paying for your equipment over time, SimpliSafe will likely be the more affordable option that still has excellent services and systems without sacrificing the importance of your home’s security.

  • Installation

    Winner: SimpliSafe

    You need to know that your equipment is working correctly at all times, and a proper setup is just the start. ADT only offers professional installation to set up your home security equipment. Professional installation starts at $99, depending on your package. But SimpliSafe gives you a choice between a DIY setup or getting help from the pros. DIY setup is easy with the SimpliSafe mobile app, how-to videos and their instruction guide. Self-installation is free, but professional service from SimpliSafe is $79, slightly cheaper than ADT. SimpliSafe is our preferred pick for installation because it gives you options, which are both cheaper than ADT’s.

  • Home Automation

    Winner: ADT

    When it comes to home automation, ADT home security is a step ahead, with some products featuring Z-Wave technology to connect your system to your smart home devices. ADT’s Z-Wave connectivity lets you pair Amazon Alexa, Google Assistant and other devices to your system for all-in-one mobile control. SimpliSafe has the same compatibility, but ADT offers a wider variety of products that pair with your system for more control of your home’s safety. ADT lets you easily connect garage door controllers, smart plugs, smart lights and more. And ADT’s partnership with Google will give customers more smart home features with Nest cameras and the Nest Hub Max in 2021. SimpliSafe has more limited home automation compatibility options with Amazon Alexa, Google Assistant and August Smart Locks.

  • Monitoring

    Winner: SimpliSafe

    Monitoring services help give you peace of mind that everything’s all right, even when you’re not looking. ADT offers award-winning 24/7 professional monitoring with remote arming and disarming using your ADT mobile app. You’ll have both environmental and intrusion monitoring starting at $57.99 per month with a contract. But SimpliSafe gives you two monitoring options: You’ll be able to self-monitor your home using surveillance and the SimpliSafe mobile app, or you can choose 24/7 professional monitoring to give you peace of mind without checking in. SimpliSafe’s professional monitoring starts at $14.99 per month without a contract making them the ideal provider with more monitoring flexibility and affordability.

  • Contracts

    Winner: SimpliSafe

    ADT requires a minimum 12-month contract, but a 36-month contract is generally required for home automation and surveillance. And you may have to pay hefty fees if you need to terminate the contract early. On the other hand, SimpliSafe doesn’t require contracts, and you can pay for its services monthly. Best of all, you can cancel anytime without any penalties. We love that SimpliSafe gives their customers this flexibility and freedom without a binding agreement.

Our Pick: SimpliSafe

SimpliSafe is our all-around best pick. You’ll have flexibility, affordability and peace of mind. SimpliSafe is an up and coming DIY provider that offers professional services and reliable equipment without contracts and fees to give you peace of mind and safety. 

That said, if you’re a homeowner looking for traditional home security, ADT may be your best choice. You’ll get hassle-free installation and monitoring to give you peace of mind that your equipment is installed correctly to help keep you safe.
