We also considered a couple of security giants for our list of best wireless systems. Vivint and ADT both claim to have wireless security systems. But this isn’t totally true, at least not according to our wireless/wire-free definition.
Equipment from both companies uses wireless connections like your home Wi-Fi, radio signals, and cell signals. But they aren’t completely wire free.
Vivint’s SkyControl panel and more current Smart Hub control panel require installers to drill holes in your wall to connect to a power source. The newer Smart Hub requires a 12 VDC power source, making it only kind of wireless.
On the other hand, the cheapest ADT option requires a landline, or you can choose its cellular system for $44.99 and up for smart home capabilities. ADT requires a contract but Vivint lets you go contract-free if you drop a lot of money up front.
Both companies are worthy options if you want a recognizable, professionally installed home security system. But they both have confusing pricing, policies, and contracts that could lock you in for several years, and neither fits our definition of wireless.
