Whether you own your home, live in a rental, or simply want to stick to a budget, we recommend checking out our top pick: Ring Alarm. It delivers the biggest bang for your buck with one of the cheapest monitoring plans at $20 a month. It's also the most comprehensive plan under $25.
Ring Alarm doesn't have the cheapest equipment on our list (especially if you count its cameras and doorbells). Still, it's more affordable than offerings from budget security rivals like Abode and SimpliSafe. Check out our list of the best cheap security systems to learn why we picked Ring over the rest.
