SimpliSafe vs. ADT Security Review

With so many home security companies flooding today’s market, choosing the right plan for you can be incredibly daunting. The big players like ADT focus on heightened innovation and efficiency, while the smaller, home-grown companies spotlight exceptional customer service and ease of use. To please today’s tech-savvy customers, competitors battle to tote the best pricing, contracts, installation, add-ons, monitoring, and smart home automation.

Among the multitude of options in 2019, SimpliSafe and ADT stand out as two highly rated, experienced companies that provide competitive pricing paired with intuitive security systems. Below, we’ll discuss the primary differences between the two companies to help you choose which would be best for you.

There are two types of home security systems to choose from: DIY and professional. With a DIY home security system, you decide whether or not it’s necessary to call the police. With professional monitoring, a monitoring center is alerted by the alarm devices in your home and calls the police on your behalf. While DIY is more cost-effective, professional monitoring is often provided 24/7 and incredibly timely, especially if you don’t have your phone on you at all times. SimpliSafe and ADT both offer professional monitoring at competitive prices with 24/7 professional monitoring and at least six monitoring locations across the country. SimpliSafe, whose professional monitoring is supplied by C.O.P.S., also provides a DIY monitoring option for those who want it.


If you’re looking for a reliable home security company that doesn’t require a contract, SimpliSafe may be the better option for you. SimpliSafe takes a “no-nonsense” approach to security, so all you need to do is buy the equipment upfront and decide whether you want professional or DIY monitoring. ADT requires at least a 36-month contract, but with that, ADT customers get more than a century’s worth of dedicated experience.

Home Automation

Today’s top home security systems give you the ability to connect your security system to your most loved smart home devices. With ADT Pulse, you can pair your security system with popular devices like Amazon Alexa and Google Assistant. This tool sends real-time alerts to your smartphone and lets you remotely arm and disarm, lock and unlock, watch live video feed and more. SimpliSafe recently revamped their entire security equipment offering to be compatible with Nest Thermostat systems, Amazon Alexa, Google Assistant and even your Apple Watch.


While SimpliSafe defaults to DIY installation (which is free) for customers who want it, they also offer professional installation upon request. ADT’s professional installation ranges from $99 to $199 depending on the package.

Can I move with my home security system?
