How We Chose These Products
We selected these systems based on the factors most buyers care about when searching for the best DIY home security systems: no-contract flexibility, ease of setup, included sensor count, app control, and backup connectivity. We also weighed whether a system was a better match for apartments, small homes, or larger properties, since “best” changes a lot depending on your floor plan. Finally, we favored kits with clear upgrade paths, because many DIY buyers want to start small and expand later without replacing the whole system.
Our ranking also considered value for money, whether professional monitoring was optional instead of required, and how well each product fits commercial-intent shoppers looking to compare before buying. Where a product offered no monthly fees, that was a major advantage for the SERP’s no-contract focus.
