Honest Dallas Security Systems

For over 40 years, we’ve never raised our $16.95 monitoring rate, and never required a contract. That makes Smith Thompson Home Security one of the last true performance based security companies in Dallas. If a company says they have great service, and won’t raise your rates, why lock you into a 3-5 contract? That’s a huge red flag. If the service or equipment is poor, you’re stuck. We have a daily motivation to earn your business, and when it comes to security systems, that’s crucial. If you don’t like us, you can fire us! Inspect verified reviews and ratings on the Dallas Better Business Bureau, you’ll find we do business the honest way. Proudly serving the DFW metro area including Dallas, Fort Worth, Texas.

Low Pressure DFW Alarm Company

We’re a Dallas alarm company that doesn’t use commission based sales people. Pricing is given right over the phone, and then we send you a licensed, background checked alarm technician. Our alarm techs will never sell you new security system unless it’s absolutely needed or desired. We can take over most existing alarm systems by simply adding our wireless transmitter to it, and switching you to our $16.95 monitoring service. Whether you choose basic wireless monitoring, or choose to upgrade to smart home security with cameras, we’re a DFW alarm company that will find the most cost effective solution to accomplish your goal in the Dallas, Fort Worth area.
