Stop Sending Employees to Check on Alarms
When an alarm goes off after hours, someone has to go check on it. Too often that’s a manager or employee who isn’t trained for what they might find. Our alarm response officers go instead: they check the property, secure it, contact police when needed and report back, so your people stay safe at home. That’s exactly what our alarm response services in Chicago are designed to do.
Response and lockup is one of our most practical security services in Chicago. It costs far less than an overnight guard and pairs naturally with mobile patrol, giving your property regular checks plus a fast response when something trips the alarm.

Why Use a Professional Alarm Response Service?
Most alarms are false, but you can’t know which ones until someone checks. Sending an employee is risky, and waiting until morning can mean a door left open all night. A trained response officer checks every alarm quickly and safely, and handles the property until it’s secure.

Alarm Response & Lockup: Common Questions
How much does alarm response cost in Chicago?
Alarm response is usually priced per call or as a monthly plan, and lock-up is priced by visit. Both cost far less than a full-time guard. Contact us for a free quote based on your property.
How quickly will an officer respond?
Response time depends on your location and the time of day. We’ll discuss expected response times for your property before service begins.
Do you work with my alarm company?
Yes. We can be added to your alarm company’s call list, so we’re contacted automatically when your alarm is triggered.
What if there’s been a break-in?
Our officer secures the scene, contacts police and stays until it’s safe, then notifies you. If you need an officer on site afterward, our emergency staffing service can help.
Do you provide alarm response outside Chicago?
Yes. Like all of our security services, alarm response and lockup is available across the Chicago suburbs, including Des Plaines, Park Ridge, Elk Grove Village, Schaumburg, Skokie and Rosemont.
