About St. Louis

Named after Louis IX of France, St. Louis is known first for the famous Gateway Arch, built between 1963 and 1965 as a monument to St. Louis’ 19th-century role as the gateway to the west. However, as the largest metropolitan area in Missouri with more than 2.8 million residents, St. Louis has much more to offer than the Arch. The St. Louis metropolitan area is home to two major sports franchises in baseball and hockey, as well as nine Fortune 500 companies, including Ameren, Edward Jones and Reinsurance Group of America, to name a few.

If you live in St. Louis, or will be moving there soon, you may want to consider a home security system. Here we’ve detailed some of the best providers in the area, to help you make your final decision.

St. Louis Crime Statistics

According to the 2018 FBI Crime Report,  larceny-theft is the most common crime in the city of St. Louis. There were also over 3,500 aggravated assaults, almost 3,000 burglaries, and over 2,700 robberies. Unfortunately, St. Louis has a slightly higher rate of aggravated assault than similar-sized cities, but this may be due to reporting differences. Because St. Louis County is separate from the city, and home to 89 municipalities of its own, these crime rates don’t account for the entire metropolitan area of St. Louis.

  • 12,413 incidents of larceny-theft
  • 3,577 incidents of aggravated assault
  • 2,979 incidents of burglary 
  • 2,750 incidents of motor vehicle theft 
  • 1,452 incidents of robbery

Factors to Consider When Buying a Home Security System

  • Price & Contracts

    Are you looking to pay for your equipment upfront or finance over a period of time? You’ll also need to decide whether you want to commit to a contract or have the freedom to cancel your provider’s service without penalty.

  • Monitoring

    Choose between 24/7 professional monitoring or self monitoring. Both have its perks – with professional monitoring, a specialist is available around the clock to help, and with self monitoring, you’ll be in charge and can avoid a monthly fee.

  • Installation

    Want a professional to install your security system for you, or would you rather install it on your own? Most providers either require professional installation, DIY installation, or offer a choice of both.
