Smith Thompson Security is the largest family owned and operated, full service alarm company protecting thousands of families and small businesses in the Dallas/Ft. Worth Metroplex ; Greater Houston Area and over 150 other cities and towns in Texas since 1978. Since we proudly operate completely independent of any of the huge national companies, we have never required a long term contract or commitment. In fact, we have never had a price increase in nearly thirty years! Our monthly monitoring is still just $16.95 a month (plus tax).

Are you still monitored by one of the national out-of-state companies who never call you back after your alarm is tripped? Are they too slow? Make the switch to an independent security company that really cares and is willing to back up our promises with NO CONTRACT and no fine print. Plus now you have the choice of either traditional land phone line or Uplink cellular wireless monitoring. Go ahead, do the math. Thousands of our customers have saved anywhere from $500 to $1000 a year by ditching the old land line and making the switch to wireless monitoring.

Our commitment runs deep with two generations of our family on the job ready to respond. We have been the low cost monitoring alternative since 1978!
