Our Picks
What to Look For
When comparing products in this category, focus on three things: warranty length (longer = manufacturer confidence), real-world reviews from the past 6 months (older reviews may not reflect current quality), and compatibility with what you already own (battery ecosystems, smart home hubs, mounting hardware). The cheapest option is rarely the right one once you account for replacement and frustration.
Our picks above are products we install on the job. They earn the spot through repeated reliability across hundreds of customer homes — not from sponsored partnerships or marketing budgets.
