Winner and Loser Categories

Packages, Equipment and Pricing

Winner: ADT

ADT and First Alert both offer viable equipment options and use similar technology. ADT wins the category because First Alert Professional equipment costs can vary greatly.

ADT packages feature primarily excellent Honeywell/Ademco or DTC technology, run approximately $30-50 a month depending on features and come with round-the-clock monitoring. But, users should note the packages themselves are barebones and will more than likely require equipment additional add-ons at significant out-of-pocket cost.

First Alert Professional sells systems through independent dealers, leading to varying local experiences. Though equipment prices can vary highly, First Alert Pro is owned by Honeywell and offers high quality technology. There is also a large selection of offerings and available customizations. Prices for monitoring contracts, installation and activation vary by dealer.
