Smith Thompson Security offers high speed, low-cost alarm monitoring and smart home technology with no contracts. Since 1978, the company has never increased its base monitoring rate or required contracts. Smith Thompson provides monitoring services primarily for consumers with an existing home security system. Its monitoring services are from a designated monitoring center and Smith Thompson Security professionally installs upgrades to existing systems as well as installs new systems purchased through the company.

The Good

  • Affordable Monthly Monitoring
  • Professional Installation
  • Private 24-Hour Professional Monitoring
  • Versatile Monitoring Options
  • Transparent Pricing
  • Flexible Payment Plans with Low-Cost Startup Option
  • Upgrades on Existing System or Installation of New System
  • No Contract

Affordable Monthly Monitoring

The base monitoring rate is $16.95 per month with no contract. This is the same rate Smith Thompson Security has had since 1978. The provider offers a total of three monitoring plans: wireless monitoring for $16.95 per month, wireless monitoring with smartphone control for $21.95 per month, and full smart home automation with video for $29.95 per month. None of the plans require a contract. Most alarm companies charge more with each device you add, but Smith Thompson does not; each plan has a flat rate.

Professional Installation

Smith Thompson uses licensed and background-checked professional technicians to install its equipment. This gives you the peace of mind that the installation and setup are done properly, which is important when dealing with devices like a motion sensor, thermostats, door locks, garage control, water sensors, security camera, etc. For about the same cost of a DIY installation, Smith Thompson will install all of the equipment for you, which saves the customer time and worry. 

Private 24-Hour Professional Monitoring

Smith Thompson owns and operates its own private 24-hour monitoring center based in Plano, Texas. This gives Smith Thompson full quality control and the ability to quickly respond to alarms and notify police in the event of an emergency. The security company's private monitoring center is UL Listed and Certified. That means the company voluntarily opens itself up to yearly audits to ensure the safety of its customers.

A few examples of how this is accomplished would be dual uninterruptable power supplies and diesel generators, fully redundant servers, backup servers, fully redundant telephone networks, independent backup phone system on-site, underground and fully supervised utilities, and disaster recovery plans.

Versatile Monitoring Options

Smith Thompson offers three easy-to-understand monitoring plans. None of the plans require a contract. Plan one is $16.95 per month and offers 24-hour cellular monitoring service of a standard alarm system like the popular DSC or Honeywell.

Plan two is $21.95 per month and offers everything that Plan one does, but it adds smartphone remote arming and disarming control.

Plan three is $29.95 per month and offers full smart home automation from Smith Thompson's mobile app. A few examples of the smart home automation offered is the control panel, video doorbell, indoor and outdoor cameras, smart thermostats, smart locks, smart lights, flood sensors, arming notifications and reminders, garage control, and more.

Transparent Pricing

Smith Thompson keeps the monthly monitoring rate separate from the equipment cost, so you know exactly what you’re paying for. It’s common for alarm companies to hide your equipment cost in a higher monthly rate, as a way to finance it. With Smith Thompson, once the equipment is paid for — whether you pay upfront for a discount or finance it — all you have left is the low monthly rate with no contract.

Flexible Payment Plans with Low-Cost Startup Option

Smith Thompson Security offers flexible payment options. You get a discount if you choose to pay upfront with a one-time payment, or you can pay it over 12 months. You can also spread payments out over 60 months.

Upgrades on Existing System or Installation of New System

A homeowner with an existing security system also have the added benefit of avoiding costly equipment and installation fees that are required by competing home security companies. The lowest costs offered through Smith Thompson are geared toward consumers with an existing security system; however, it does provide equipment options to consumers without an existing system.

Smith Thompson’s standard alarm package and smart home package are the same price; the only difference is the monthly rate. The alarm packages are $499 with a 12-month payment plan, or you get $100 off (making the price $399) if you choose to pay upfront as a one-time payment.

Each package includes the main keypad, wireless door sensors, motion detector, siren, backup battery, and free installation. If you choose the smart home package, the keypad is a touchscreen and has the ability to integrate with smart home Z-Wave devices and cameras. 

No Contract

Smith Thompson functions on a month-to-month contract basis. While many security companies require contracts of 36 months, Smith Thompson allows consumers the freedom of a monthly agreement. Consumers can cancel services anytime by providing a written notice 30 days prior to their desired date of canceling services.

Smith Thompson notes it is a performance-based alarm company, and it believes if it treats its customers right, they will stay loyal without a contract.

The Bad

  • One-Year Equipment Warranty

One-Year Equipment Warranty

A warranty on a Smith Thompson security system has the potential to protect consumers from the high costs associated with repairs. Smith Thompson only offers a one-year warranty on products installed by its technician. However, this is somewhat common within the home security industry.

The Bottom Line

Smith Thompson offers affordable, flexible security and smart home options for Texas residents. Consumers with an existing security system will benefit from the low upfront and monthly costs, while those in need of a new system can also access affordable options through Smith Thompson. The company has a long history and proven track record since 1978 and has maintained its customers without contracts by delivering fast, friendly, and reliable service.

We recently became customer's of Smith Thompson Home Security. We were looking for a less expensive service than the one we had been using and wanted a wireless system. I called this company after seeing ads in local print media. Their pricing seemed quite reasonable. After speaking to a polite and knowledgeable representative, I made an appointment to have their system put in our home. The installer arrived promptly for his appointed time and removed our old system, installing the new. He was patient, answered all our questions and was careful not to leave any mess. He even neatly boxed up the old system we were recycling! He trained us quickly on their equipment and left a "cheat sheet" in case we forgot anything. We were pleased with the ease and professionalism of the install and are happy with the monitoring service.

First and foremost, they had the most competitive price on the market. Secondly, they were able to use my existing equipment which was one of the main things that I was looking for. And lastly, they were on time, very courteous, knowledgeable, and efficient. The technician was in and out in less than an hour. And given the current pandemic, he wore a face mask, show coverings and kept a safe distance the whole time. I highly recommend Smith Thompson for all of your home security needs.

I’ve had two alarm occurrences in the last 30 days! I forget because the old company, ADwhatever, never responded. Smith Thompson called me within 30 seconds! Great company!

We have really loved our experience with Smith Thompson. 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.

I have had Smith Thompson now for 7 years . I have wireless motion sensors and wireless open sensor on garage door and is a heavy duty large so if the door moves in the wend system will not go off all was recommended by the installer and no wiring had to be added. I do self test every month which everyone should do no matter the security system you have only once had to do a reset caused by lightning strikes and a power surge. I like that they give you the option to pay once a year and give a discount of one month for doing this for the price you cant beat even with cameras.

We recently moved to the area from Pennsylvania and one of our new neighbors recommended Smith Thompson Home Security to monitor our alarm. We are not disappointed at all in the quick response, service to install, start up, and in the professional manner Shawn explained everything to us. I'm very impressed that there is no contract, and if you are not satisfied you can just cancel the service. Did I mention they price? It is a bargain!

Where to start. First off, the monthly monitoring price is the best in the industry. From the first time I made contact with Smith Thompson to the time the technician left my home following install, my experience was stellar. The salespeople are super friendly, the tech was great and very detailed when showing me how the entire system worked. And the few times I have inadvertently set the alarm off, the call center contacts me immediately with genuine concern. I can't say enough good things about this company and will be a customer for life!

I was very happy with the technician that activated the system in my new house. He was very friendly and did the job quickly. Smith Thompson is the best deal out there for monitoring. At $16.95 a month, there is not another company that comes close. They have good service too. Had a false alarm just the other day, and their call came in under ten seconds. Very glad I chose Smith Thompson.

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!

Have had Smith Thompson for at least six years. Love the cost, the cellular alert to their monitoring station, and their rapid response to each alarm. They also offer a one month discount if you pay for a year of monitoring up front each year.

When I used Smith Thompson Home Security in the past, it was easy to schedule an appointment. The technician who came to the house, Greg, called in advance and was on time. He was extremely knowledgeable and personable and patiently explained to me how the system worked. He answered all of my questions in a professional manner. When I later called tech services, the employee was also very knowledgeable and professional. I’d highly recommend using Smith Thompson for home security needs!

Do not use Smith Thompson, All they care about is trying to get more money out of you and every answer is you need a technician, and 5 of 5 five times this has been a lie. Any issue I have had has been on the company side or a simple software setting. All that can be done remote.
