‘Same Rate Since ‘78’

We have kept the price of home security in Celina the same for more than 40 years!

There is so much financial insecurity these days that it remains one of our proudest points that we have not had to raise our rates since 1978. This allows us to continue to provide premium home security services for the people of Celina, without putting the undue stress of ever-rising costs on our customers. Maybe other home security companies need to make more and more money every year, but we don’t, and you can count on our consistency.

Industry-leading home security systems in Celina without a contract! We don’t have to trap you to keep you as customers!

When it comes to signing up for utilities, many companies require you to sign a contract, locking you into using their company for 1-5 years. Signing a contract would be fine if you knew they provided excellent service and had affordable rates, but there’s no way to try the service to see how you like it. With Smith Thompson Home Security, we don’t require our customers to sign a contract, meaning you’re free to move onto another company if you aren’t completely satisfied.

There’s no such thing as a “free” alarm system, those companies are scamming you

Sure, you get an alarm system without paying a large initial cost, but they will make you pay nonetheless. The first thing they will do is lure you in with equipment that they tell you is free, but is only added into your monthly fees. Then you’ll sign a contract, locking you into the deal for at least a year or two. Then, your introductory monthly fee expires, and you are left with a ridiculously high fee that continues even long after the hardware is paid off. The worst part is since there is a contract involved, leaving early will generally involve a stiff early-cancellation fee, and in some cases, you may need to return the alarm equipment as well.
