Because they’re so different, determining whether ADT or SimpliSafe is the best home security system depends on how much you want to spend and whether you want to DIY your installation and monitoring. Here’s the gist:
SimpliSafe is like paying cash for a small house. It's all yours, and you might not have much in the way of monthly fees, but it requires a little more work, it costs more up front, and if anything breaks, it's on you to fix it.
ADT is like signing a mortgage for a nice condo. You get high-end appliances, and you don't have to worry about maintenance, but you pay a hefty fee every month—and technically you don't own any of it.
