Family Owned & Operated since 1978 in Texas. We own and operate our own UL listed dispatch center right here in Texas, and that’s how we’re able to offer high quality monitoring at a great price. We are the largest independent alarm company in Texas. Honest Dallas Fort Worth 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.
