Retail Security Systems in St. Louis & St. Charles

Always Have An Eye On Your Business

Citywide Alarms designs, installs, and monitors retail security systems built around how your store actually operates. Whether you run one boutique or a dozen locations, your store needs to be equipped to stop theft and stay protected at all hours. 

Premium Local Security Solutions

Every Retailer Needs Professional Protection

Retail security comes down to four priorities, whether you run one store or a dozen: reducing shoplifting, preventing after-hours break-ins, managing who has access to what, and seeing every location from anywhere. Our retail security cameras, alarms, and access control work together as one system, so a problem at the register or at the back door comes with video that shows exactly what happened.

We Know The Issues You Face. We Have The Solutions You Need. 

Reduce Shrink

Visible cameras at entrances, registers, and high-value displays are shoplifting prevention that works before an incident occurs, and smart detection flags activity that needs attention so staff can respond the moment it's happening.
.
Stop After-Hours Break-Ins

Door, motion, and glass break sensors detect an entry, and video-verified alarms let monitoring confirm what's happening, so police get a confirmed event instead of an unverified alarm. For storefront glass, 3M security window film holds the pane together during a smash-and-grab attempt, which slows entry and buys time for the alarm. 

Manage Employee Access

NRF’s 2023 survey put internal theft at 29 percent of shrink, which makes access a loss prevention issue and not only a convenience. Individual user codes and card access give every employee their own credential, so you can see who opened what, and when.
.
Check In on Every Store From Your Phone

A store does not stop needing attention when you leave it. From your phone or tablet, you can view live and recorded video, receive alerts, and confirm what happened without driving in.
