Who hangs the keypad, and who answers after an I-64 last drive
This site is the St. Louis order line. SafeStreets, an ADT Authorized Provider, designs the system for your house and installs it. ADT monitors it 24/7 from U.S. centers. We are not ADT corporate, and we are not a do-it-yourself kit.
A Soulard brick house, a Lafayette Square Victorian, a Hill bungalow, and a Chesterfield new-build all get the same kind of watch. The quote changes with how many doors and windows you have — and whether a leftover keypad is already on the wall.
Call with a ZIP in the City of St. Louis, Clayton, Kirkwood, Chesterfield, Webster Groves, St. Charles, or the county towns we name. You will hear the monthly price, the $99 install on many plans, and whether your city wants an alarm permit.
The hours the house sits empty — that is the product
Weekdays empty a lot of St. Louis houses after the I-64, I-70, I-44, or I-55 drive, a Kirkwood or Parkway drop-off, or a WashU class day. That is when people want someone watching the doors — not a camera they forget to check from Clayton.
Doors, windows, and the garage
Sensors go on the doors and windows you actually use, including the garage. If someone opens a door while the system is armed, ADT can call you and request help.
Boxes on the stoop
A doorbell camera is the usual add on Soulard and Lafayette Square porches. Outdoor cameras if you want the driveway. Monitoring still works if you skip video.
Smoke, CO, and Ameren storm nights
Add a monitored smoke or carbon monoxide detector if you want it. The panel can still reach ADT if Ameren Missouri or the Wi-Fi drops. That is why we mention backup on the quote.

Hear the price

SafeStreets installs
A technician installs and tests everything, then shows you the keypad and the app. We confirm the install window on the call.
ADT watches it 24/7
If an alarm trips, ADT can call you and request help based on the type of alert.
Streets and suburbs we actually schedule
Professional install across these St. Louis neighborhoods and the Clayton, Kirkwood, Chesterfield, and St. Charles towns we name. If your city requires an alarm permit, we will name the office on the call.
City of St. Louis ARFAM is $25. The ZIP still decides the desk.
Inside the city, Ordinance 66264 requires a $25 residential alarm registration through ARFAM. For a monitored system the alarm company collects the fee. False alarms in twelve months: 1st $0, 2nd $25, 3rd $50, 4th $50 plus a 30-day suspension. Unincorporated St. Louis County Chapter 720 bills $25 on every false alarm police respond to. St. Charles is a one-time $25 registration. Other desks confirm from the ZIP — we do not invent a dollar for a city we have not confirmed.
SLMPD reported about 140 homicides in 2025, a 12-year low, with Part I crime down 16 percent versus 2024. Those are citywide numbers, not a report card on your street. People order monitoring for the hours the house sits empty. Police Chief Robert Tracy and Mayor Cara Spencer are in office. We do not publish neighborhood crime rates.
What people remember after install day
On time. Patient with the keypad. Did not leave until the app worked.
“The installer arrived on time, installed everything efficiently, and walked me through the control pad and app.”
“Nicholas worked late into the evening to get the job done. Patient and on time.”
“Moved into a new home on my own. Phone quote, install in a few hours, and I sleep better.”
