ADT has finally embraced a DIY home security system. After being in business for almost 150 years, ADT acquired LifeShield in 2019 to offer a DIY system for those who don’t want to hassle with professional installation. Now you don’t have to worry about installation fees, missing work to be home for the installer to arrive, or given that there’s a pandemic, welcoming a stranger into your home. That’s because it’s easy to setup your Blue by ADT system yourself, and we’ll show you just how easy. But is Blue as good as other DIY home security systems? And with the fairly new acquisition, are you getting more ADT or more LifeShield, and is either of those a good thing? Our experts find out in our Blue By ADT review.
