How Audio Intrusion Detection Catches Criminals Before Cameras Do

Most commercial alarm systems rely on motion sensors and video cameras. But when an intruder slips past a blind spot or breaks in after hours, you don’t need another grainy recording—you need a system that stops the crime as it happens.

That’s where Sonitrol’s audio intrusion detection makes all the difference.

Unlike traditional systems that wait for movement or hope an intruder steps into view, Sonitrol detects the sound of forced entry the moment it begins. It’s a real-time alarm system with audio verification—backed by a live operator, not an app alert or motion-triggered footage.

The Problem with Camera-Only Systems

Video surveillance has its place, but it’s not built to stop crime in real time. Most systems only detect movement after someone has already entered the space. And unless that movement is caught clearly on camera, the alarm may never be verified.

Common issues with camera-only systems:

• Most camera systems only record and are not monitored
  
  
• Blind spots in coverage
  
  
• Delayed detection or missed activity

Why Audio Makes the Difference

Sonitrol’s real-time audio security systems detect the actual sounds of forced entry—glass breaking, security bars being removed, doors being pried open, or movement inside restricted areas. When a sound triggers the system, a live feed is sent to Our ULC-certified monitoring stations where an operator can verify the event and dispatch police immediately.

Unlike motion or video triggers, audio can detect what cameras can’t see. It covers the entire space—regardless of lighting or angles and cannot be blocked by raking or pallets.

In fact, according to the Security Industry Association (SIA), “Verified response reduces false alarms and improves resource allocation. Systems like Sonitrol’s audio verification can make a critical difference in deterring break-ins or assisting Police with the capture of criminals before they escape.” That level of confidence is why so many law enforcement agencies give Sonitrol alerts priority ONE Dispatch document at 3 minutes.

Faster Response, Fewer Losses

Because Sonitrol verifies each intrusion in real time, police treat every call as a crime in progress—not a routine sensor trip. That means:

• Police response in as little as 3 to 4 minutes
  
  
• Fewer false alarms (industry-leading 3%)
  
  
• Over 188,000 confirmed criminal apprehensions
  
  
• Proven deterrence—criminals avoid Sonitrol-protected sites
