Is Smith Thompson Security a Good Choice?

After extensive testing, we found the Smith Home Security Company to be a reliable option. We like that their monitoring rate starts at only $16.95, and they offer smart home automation. That said, we believe that SimpliSafe Home Security is a better choice for no-contract security.
