“Free” alarm systems are the industry’s dirtiest trick.

Companies that give “free” systems are simply hiding the equipment cost in a high monthly rate of $50-$70/mo. We’ve been around since ’78, so we know what parts really cost. That equipment is actually paid off within the first year, but do they lower your rate once it’s paid for? NO. You end up drastically overpaying, and likely for 3-5 years under a contract. “Free” systems are not free. It’s insulting, really.


We offer transparent pricing.

With us, you know what you’re REALLY paying for. The equipment price is separate from the monthly monitoring rate. Once the equipment is paid for (whether you pay upfront for a discount, or finance it), all you have left is our low monthly rate. No contract. If you do the math over a typical 36 month term like most companies require, you’ll find we’re a MUCH better deal.


Setup FAQs

Most of the time it costs little to nothing to update your system. We have a true online quoting system here that can help give you a better idea. Or give us a call, our sales people can usually pinpoint what needs to be done right over the phone. 888-888-1695 Press Option #1

Our technician will collect your first billing cycle of monitoring to get your service started, and you’ll have two options. Monthly Auto-Draft, or you can pay annually and receive 1 free month (pay for 11 and get the 12th free). For your equipment, if you chose to pay upfront the technician will also collect for that. Or if you chose to finance the equipment on 12 months same as cash, you’ll pay the initial minimum monthly payment.

It’s similar to what you’d see at a Best Buy or appliance store. If you pay off your financed equipment total within 12 months, you pay no interest. There’s a low monthly minimum payment requirement, no early payoff penalty, $500 minimum loan amount, and quick credit application that takes seconds to get approved.

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 days 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 they’ll be glad to help out. Dial 888-888-1695, press option #1

Not anymore! All new customers are setup with cellular wireless monitoring. Drop that costly landline phone.

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!
