A cheap home security system doesn't have to be a cheap-feeling one. Every pick in this list costs under $300 to start and under $20/month to monitor — and each one still passed our core intrusion tests.
We install every kit ourselves or hire a pro when required, run sensor-level intrusion tests, time monitoring dispatch with a retired 911 dispatcher on the line, and re-verify pricing monthly. Read the full testing methodology.
