Ready to automate? Let our smart home security systems take your San Antonio home to the next level of sophistication.

Shopping for a smart home security system in San Antonio with a little more advanced features? Look no further. Our 7” touchscreen IQ2 panel is attractive with its ultra-thin and sleek design that resembles a phone and has a built-in photo frame to display all your favorite photos. Plus it easily works with cameras and is smart home ready. The IQ2 panel comes with a built-in app control so that you can easily access all your favorite features from just the palm of your hand. It also is connected by LTE cellular wireless or wifi, ensuring your system gets responded to quickly and efficiently while also having the capability of interacting significantly faster with your smartphone app. In addition to all these amazing features, the IQ2 panel uses Power G sensors and encrypted sensors. This means that the sensors have military grade 2-way encryption, ensuring your privacy is highly protected. Most companies cut corners with this type of encryption, opening up your system and home to a possible invasion or privacy breach. We value your privacy and safety too much to cut that corner. Our Power G sensors also have automatic signal adjustment that helps to improve battery life and ensure reliable connection, as well as, inference circumvention that ensures your signals never get blocked by other wireless protocols. Along with all of these features, you’ll also have access to Bluetooth touchless disarming and a built-in glass break detector. IQ2 works with most existing alarm sensors while also being compatible for devices like indoor/outdoor cameras, z wave locks, lights, thermostats, and garage door openers.

“Free alarm systems” are nothing but gimmicks.

“Free” alarm systems have hidden agendas. What you don’t realize when purchasing a “free” alarm system is that the cost of the system is rolled into your monthly contract. While the system will be paid off within the first year, you will still be paying those outrageously large monthly bills! What’s more? You are now stuck in a 3-5 year contract that forces you to overpay for far too long!

We’re an honest and transparent San Antonio alarm company.

At Smith Thompson Security, we pride ourselves on our transparency with San Antonio home security customers. We will never hide equipment fees by creating large monthly rates for our customers. Instead, we believe that showing you the price of the equipment and monitoring rate separately is the honest thing to do. This ensures that you know exactly what you are paying for. Even if you decide to take advantage of a financing option, when it’s all paid off you will only be left with our low monthly monitoring rate.

No Contracts. No Price Increases.

What our customers say

Excellent Reviews

Don’t take our word for it, look us up. We have excellent ratings on the Better Business Bureau, Trustpilot, Nextdoor, Angie’s List, Google, Yelp, and Facebook. Since 1978, we’ve worked hard to establish and maintain a solid reputation, and our online reviews back it up.

Top notch home alarm monitoring at our Texas call center.

Many people don’t know what they are signing up for when they get a home monitoring system. They think they will get customer service from the company they purchase from but, unfortunately, they are not. In fact, after most alarm companies install the system, they sell your account to a 3rd party monitoring center. This means that your account is now handled in a center that deals with millions of other customers from thousands of different companies. Not the level of customer service and expertise you were expecting, huh? Smith Thompson doesn’t play that game. Instead, we keep all of our monitoring in state. We own and operate our own private, 24/7, UL Listed and Approved, dispatch facility right here in Texas. Let us install it, service it, and monitor it for you.
