Beware!! I just switched to a reputable Security Company that doesn’t charge you to come out and fix their faulty key pads. Smith Thompson has pathetic Customer Service.

We honor all parts that are under warranty, and we use the largest brand names in the industry: Honeywell, DSC, Qolsys. We're sorry things didn't work though.

They used to be so good. Now their employees are just plain rude. And they use the crappiest equipment that CONSTANTLY breaks. I’d recommend going with a more professional monitoring company.

Sorry to hear you had a bad experience. As far as the equipment goes, we use the top names in the industry: Honeywell, DSC, and Qolsys. Most of the time though, we just take over existing equipment that wasn't even installed by us.

Smith Thompson takes care of my security and pest control. This visit this time was quick and very easy. Technician was very polite in answering all my questions. Will always use this service.

I asked them to install a second doorbell camera which they did and then after about a week it failed. When the technician came out he said the transformer in the attic blew out and I would have to replace it myself. Now I want both doorbells removed and leave me with regular door bells. This guy was a real jerk.

Horrible system. Cameras constantly disconnect. When they do connect, they only stay connected for maybe ten seconds. Service department is useless.

I have been a customer for several years, and the few times I have accidentally tripped my alarm, ST has called quickly. Recently I had 9 windows replaced in my home, and I needed to have them reestablished for the alarm system. The ST installer performed the attachments quickly. I asked him about a new keypad, and he took the time to check for existing wiring in the attic (it was there). He took the extra step to install the keypad and did so in a quick and efficient manner. And did I mention he was such a nice guy? (I wish I could recall his name.) Love these guys.

If I could give them 0 stars, I would. Had their service since 2015. Their equipment broke and they won’t replace it nor will they come remove what they wired in to my house. Literally- the hardware is broken and they want me to pay a service charge as well as pay for new equipment. They also said that we installed their equipment (because they said they didn’t) and that they won’t remove it but I am not an electrician or technician to be able to do any of this. It is a fire hazard with their property and they will not service it. Stay far away!!

I have been a customer of Smith-Thompson Home Security for approximately 10 years in two different houses and have always found to be prompt, efficient, friendly and reasonably priced. Recently I had a problem with my Alula remote device. I called the technology department and they quickly scheduled an appointment. The technician arrived on time, checked the home device, installed a new unit and double checked the entire system. He explained the problem, fixed it and now I feel safe and secure. I would highly recommend Smith-Thompson.
