Free Home Security Matching · All 50 States Mon–Fri · 9am–7pm ET Not a security company, a free matching service Email Us

Security Help Guide is a free service that connects homeowners with local security companies and installers. We are not a security company, alarm dealer, or monitoring provider, and we do not sell, install, or monitor security systems.

The short answer

There is no single price. Starter equipment commonly runs a few hundred dollars. Professional monitoring, when you choose it, averages about $20 to $60 a month. Professional camera installation adds labor of roughly $80 to $200 per camera. A self-installed, self-monitored system can keep ongoing cost near zero.

Estimate your own numbers with the camera cost calculator and the coverage planner.
