If we set off the alarm they are on the phone before we can even turn around. Have never had this great of service.
We always call and check on you right away, we own and operate our own UL Certified Central Station so our response times are the quickest in the industry, since nothing is done by third parties with us. Appreciate you!
Loved making the switch to Smith Thompson! So much more affordable. No gimmicks. No tricks. Just straight forward security system and monitoring for a low price. I haven't had any issues with them at all! Highly recommend supporting this company!
That's right, no gimmicks, and no fine print! Thank you for your trust!
Great pricing, excellent response time in an emergency, professional and helpful staff. One of the best in the industry we have experienced in last 40 years.
Thank you! The main reason our response time is so quick, is that we only monitor our accounts in our company owned UL Certified Central Station, with full back up. Most companies use a third party monitoring center that monitors millions of customers from thousands of alarm companies.
Smith Thompson provides an excellent monitoring service for a very affordable price with a great customer service. Their pricing is one of the lowest in the industry which is hard to beat. Their customer service is excellent with their staff being very professional and polite. I highly recommend them for the home monitoring services.
Appreciate your confidence, thanks again!
Nobody likes over paying for simple home alarm monitoring, thanks for your business!
Smith Thompson has very competitive pricing (they beat all of the companies that I checked with) and were able to use my existing system. They were on time, very professional, and very efficient. I highly recommend them for all of your home security needs.
Typically, we can use the existing equipment in most cases, to further save you money. We appreciate your business!
We were referred to Smith Thompson through a family friend. They raved about their prompt and friendly service, affordability, and no contract service. We were skeptical at first cause it all sounded too good to be true. Turns out it wasn't! The service technician was out at our house at the drop of a hat, and was very knowledgeable, courteous, and clean (facemask, sanitizer, etc.etc.). Price/month is amazing & the service since has been flawless. I had ADT in the past, and will never go back. You can't beat Smith Thompson.
Thank you!!
I had my service started on 07/01/2020, the service person was clean and efficient. He set up my service in less then an hour installed a new board so I may use my smartphone to activate the alarm. IT did not work, and it is going to take two weeks before someone can come out and make repairs. I just regret paying up front when I could have been billed.
Sure sorry for the delay, apparently we had a bad piece of equipment, but we will sure make it right for you! And we only usually only collect the first month's service, and would be happy to return it to you just to make you feel comfortable.
Smith Thompson was great! They helped secure every entrance, even ones I hadn’t thought of, educated me on their app, and charge a low flat fee.
That's right, no hidden cost, just a flat monthly rate, that hasn't changed in over 42 years!
They’ve been wonderful to work with. They were incredibly polite on the phone and made the transition super easy and were quick and sanitary during instillation
We appreciate you!
Originally used ADT for security and they were charging me $65+ a month for security and other features I didn't even have. I was recommended to use Smith Thompson and have not been more pleased. Only paying around $20/month without a contract is a steal. Thanks!
Home Alarm monitoring has always been (and continues to be) much too expensive. We have always had our base rate of $16.95 per month, and it has never changed (actually it has gone down over the years) in over 42 years. We do not outsource our 24 Hour monitoring, which helps us keep our costs down. We appreciate your business!
I'm going on my three month with Smith Thompson and I couldn't be more pleased with the system it's self and the customer service i have received. After install I had one window that would not set and I called them and they where back out the next day to fix it. Both techs that came out were very respectful and knowledgeable of what was needed to be done to switch my system over to Smith Thompson. The full process from the time I call to get a quote through the completion was painless.
We are so glad to have you and thanks again for your kind words...and your business!
Excellent service for 15years. Immediate response when my alarm goes off. Employees are always polite, even when I have to say I set the alarm on by mistake.
Wow, thank you for the long time business! We love hearing from our customers!
They call immediately when the alarm goes off, never fails. Great service. Have recommended them to family, friends and coworkers and they are happy with the service. When I call for some trouble shooting they are always very helpful to answer and resolve problem. Has been with them for years. Great service for reasonable price. Highly recommend.
Thanks Gigi! The reason we can respond so quickly is because we don't outsource any of our monitoring, it is all done in house by our own 24 Hour UL Certified Central Monitoring Station. We appreciate you!
I was with ADT for many years and, fortunately, never had an emergency or a need to call. However, it always bothered me that they were not a local company and their security services were in an entirely different state. It was especially frustrating that they required that the customer sign a contract and each year when the contract renewed, the rate automatically increased so I happened to see an ad for Smith Thompson and decided to call. I was quite pleased with rate I was quoted and, since there was no contract to sign and I could cancel at any time, I decided to give them a try. The technician who came out was able to use my existing equipment and had to make only a couple of minor changes. He even took the time to answer some questions I had never understood about the keypad. The couple of times I have called, I was treated respectfully and full attention was given to my concern. I love that Smith Thompson is a local DFW company and I might add that their rates have not increased since day one. I would highly recommend Smith Thompson to any individual or company looking for great security service!
That's right, we've had the same rate since 1978! And thank you so much for your kind comments!
We have really loved our experience with Smith Thompson. We live in Garland, TX and had a security system in our house, but had not used it since moving in our house in 2017. We were able to get a new system installed. We called on a Wednesday and a technician was able to get to our house that weekend. The technician called us when he was 30 minutes away, called before he knocked on the door, and set up our security system in under an hour. We really appreciated how detailed the technician was in his explanation on what our security system entailed, and answered all the questions we had. Very excited about our security system.
So happy you're happy! And thank you for your confidence...and your business!
Recently switched from ADT to Smith Thompson and very glad we did. Their technician, Clint, (Austin area), was prompt, professional, and knowledgeable. This is the 4th home/security system we have had and he was the first to really explain how everything works. He was also able to use existing equipment (including stuff included with our new home that ADT couldn’t use) so our home is much more secure at 1/3 of the price. Clint was also very careful with Covid 19 safety protocols, including mask, sanitizers, shoe covers, etc. Great service!
Clint is terrific and we are very fortunate to have him onboard. We appreciate the kind words!
Very glad I switched over to Smith Thompson Security for my new house. They are very fast , efficient and most of all professional when it comes to the security of my house. I was with another company for many years, however will never go back now that I have found Smith Thompson... A very good company for home security.
Hi Michael, thanks a million for making the switch! We look forward to taking care of you for many years!
I recently switch my alarm monitoring to Smith Thompson Home Security. I installer was very professional and arrived as scheduled. The installation was very neat and quick. I like the idea of not having to sign a contract and the monitoring fee is very reasonable. I would highly recommend Smith Thompson for security monitoring. Thanks Craig N.
So glad you made the switch! And that’s right, we haven’t had a long term contract in 42 years! We appreciate your business!
Timely service after moving into our new home...very courteous and professional
Thank you so much, and congratulations on your new home! We enjoyed meeting you!
