Home Security Systems Under $100

7 of 12 models under $100 · Published in Sep 2026

7 of the 12 home security systems we track come in under $100. These are the ones worth buying at that price — camera resolution, local versus cloud recording and whether the app keeps working without a subscription. This is the tier where most people should shop: you get the main features without paying for the flagship upgrades. We keep the same ranking criteria as the full list, so a cheaper pick only moves up when it is genuinely better on those points. See all Home Security Systems >
