What is APS?

Alert Protective Services was founded by Chicagoans in 1982. Since then, we have grown to become Chicagoland’s most trusted name in home and commercial security services and products. While our headquarters are in the heart of Chicago, we service clients throughout the entire greater Chicagoland area.

As a leading security company in Chicago, we pride ourselves in offering sophisticated security systems to our residential and commercial customers alike. Our goal is to provide peace of mind to our clientele, whether they are seeking to provide safety for their families, businesses or possessions. Our experienced technicians customize security systems to meet each need so we can ensure customer satisfaction on every level.



Alarm Services

A home alarm system is your family’s sentinel against danger from outside and within. Alert Protective installs the latest in burglar alarms, CO and smoke alarms, motion sensor alarms, and more.


Home Automation

Home security and home convenience go hand in hand. Lock and unlock doors from your phone. Save money on utilities with a smart thermostat. View footage from security cameras in real time and much, much more.


Video Surveillance

Modern home security cameras warn you of uninvited guests and deter would-be criminals they strike. We only use the best products from the most respected names in the industry. These include United Technologies, Brivo,, Eagle Eye Network and others.

Customer Testimonials

5-star rating on yelp, the best place to get your alarm and security video system in the extended Chicagoland area into Wisconsin and Indiana!!!
Harry Hamilin
Used Alert Protective Services to replace my existing security camera system. Excellent sales and installation. No hard pressure sales truly consulted with me on how I should set up my new system. The installers arrived on time, were professional, and knew exactly what I wanted in terms of placement.
