Don’t have an alarm system? We can install our standard home security package for just $ 299 plus tax (Homeowners only, rental properties and commercial systems by quote only). Smith Thompson installs only U.L. Approved equipment on all of our systems and of course, the monthly rate is still just $16.95 a month with no long term contract required. Sometimes an additional fee is charged when the home cannot support our standard system. An example would be a two story home that needs some wireless parts due to wiring difficulty. Our technician will tell you up front if any wireless equipment is needed and any extra costs.
