Monitoring: Both SimpliSafe and ADT offer professional monitoring, and both monitoring companies have six redundant monitoring centers so there’s never a problem getting help.
SimpliSafe outsources to COPS Monitoring, while ADT monitoring is done in-house. Both systems have crash and smash protection and cellular backup.
Mobile app access: Both companies have smartphone apps that allow you to access your system remotely and receive text notifications and email alerts when door and window sensors get tripped or if there's an alarm event. But with ADT, you'll have to pay for a higher tier package to get access to the mobile app.
Standard equipment selection: ADT and SimpliSafe systems offer similar standard security equipment, like a wireless keypad, key fob, contact sensors, and motion sensors.
Smart home integration: Both ADT’s and SimpliSafe’s wireless security systems work with Amazon Alexa voice commands.
Shopping experience: The differences between SimpliSafe and ADT start with the shopping experience. With ADT, you'll be paired with a sales rep who will help you figure out what you need over the phone or arrange a home visit. You can get everything you need from SimpliSafe online—just click and buy. ADT has a professional installer help you determine what equipment you need to secure your home.
ADT offers pretty much every security device available, while SimpliSafe's system excludes things like carbon monoxide detectors, garage door controls, and outdoor video surveillance.
Contracts: ADT requires a lengthy three-year contract, while SimpliSafe is entirely contract-free. With ADT, you'll pay a minimum of $36.99 a month for professional monitoring for all three years you're in your contract.
Installation: ADT systems are professionally installed by a licensed technician authorized by a third-party provider, but you can install your SimpliSafe system yourself.
Connection type: SimpliSafe systems work off your home's Wi-Fi network, while ADT systems use a combination of Wi-Fi and Z-Wave technology. We found ADT's devices to be more reliable than SimpliSafe's, with more consistent connectivity. ADT’s video cameras also have a smoother feed and better night vision.
System maintenance: For a little extra each month, ADT will ensure that your devices continue to work flawlessly. This is a perk you don't get with a no-contract company like SimpliSafe.
