How it works
Here’s what to expect when we take over your existing system
A full-time, fully licensed technician will connect the wireless transmitter to your system's main control box for a small one-time charge of $89.
We’ll run a signal strength test, and send test alarms to our 24hr dispatch center to confirm success.
Keep the same alarm codes if you'd like, or have new ones setup at no extra cost. We will train you on how to use it.
Your technician will accept payment for any necessary equipment charges (will have already been discussed and approved by you first).

Our technician will collect with check or credit card on-site for any equipment we've sold you, as well as the first billing cycle of monitoring to get your service started. We have two billing cycle options to choose from: monthly (autodraft), or you can pay annually and receive 1 free month (pay for 11 and get the 12th free).
There is no contract! Since 1978, we've been able to keep our customers with great service. Should you need to stop service though, all we require is 30 day written notice.
Any equipment Smith Thompson installs comes with a 1 year part and labor warranty. If a repair is needed on equipment originally installed by another company, or if you are outside of the 1 year warranty period, it would cost $59 for the service call, plus any parts needed.
Yes! We have a true online quote system here. Or you can give sales a call during business hours, and the'll be glad to help out. Dial 888-888-1695, press option #1.

A dispatcher immediately calls you on any number you would like us to call. If we don’t receive an answer, the police or fire department are dispatched to your home. If we do receive an answer we verify your password, and at that point you can decide if you want us to dispatch or not. We never charge for false alarms.
Due to the short term nature of apartments, we do not. We recommend looking into SimpliSafe.
If we are taking over a compatible system about 45 min - 1.5 hours. If we are installing a new system from scratch about 2 hrs.
Yes, most cities and towns have ordinances requiring you to register your alarm with your local police department. Contact your local police department or city hall to obtain your permit application. Once registered, be sure to call and give us your permit number. IMPORTANT: Most police departments will not respond to your alarm without a permit!
Our state license numbers is B-02469
We don’t hide behind a contract like other companies. We have to perform 24/7, or else we’re fired!That’s the way it should work, right?
We had a great experience with Smith Thompson
recently for our home in downtown Houston! I was referred to Smith Thompson by a friend after expressing frustration with some of the larger brands that lock you into a 3 year contract. We called to inquire about the most cost-effective...
From the first phone call to the actual use of our security system we have been 100% satisfied! The technician was knowledgable and courteous. He was able to answer all my questions and get the system up and running in no time. Thank you Smith Thompson Home Security for making our home more secure and at an affordable price to do so!!!!
A breeze so far!
Everything about Smith Thompson has been a breeze so far! The tech that installed our system was extremely knowledgeable- we had a lot of questions. He was not pushy with products, just presented our options.. which I appreciated a lot. I have enjoyed the service & would definitely recommend. You can’t be the prices either!
Simple, easy, and straight forward.
We just moved into our new home... and dealt with many different companies and their representatives. So far, our experience with Smith Thomson is the best. They made it simple, easy, and straight forward -- just the way we expected. And best of all their price is very reasonable and affordable. Highly recommended. Wish to see more businesses like Smith Thompson...
