Why Indianapolis Chooses Nelson Alarm
Indianapolis is a thriving and growing city—but crime and emergencies can happen anywhere. That’s why Nelson Alarm offers home security systems and business security systems in Indianapolis that do more than detect intruders. Our systems also include fire, smoke, heat, carbon monoxide detection, and more.
From the moment a sensor is triggered, your system alerts both you and our local 24/7 monitoring center, which acts based on your custom emergency response plan—whether it’s contacting a neighbor or dispatching police or fire services.
Nelson Alarm security systems give you peace of mind, knowing your home & businesses are protected day and night.
Protect What Matters Most with Advanced Security
The safety of others and the protection of your home and/or business are always top of mind. Nelson Alarm’s advanced security systems are designed to detect threats before they escalate—whether it’s a broken window, opened door, or unexpected motion. When triggered, an audible siren activates immediately, alerting your household and deterring intruders on the spot.
In the U.S., a burglary occurs approximately every 15 seconds—often in broad daylight when homes or businesses are unoccupied. Fires remain a major threat as well, with one breaking out nearly every 30 seconds and causing more fatalities than any other type of disaster. Whether you’re protecting your family or your livelihood, Nelson Alarm delivers fast detection and 24/7 local monitoring for intrusions, fire, and more—so you can focus on what matters most.
Smart, Scalable Security for Homes and Businesses
Our advanced Honeywell Pro Series systems are built for both smart homes and secure commercial properties. With a 7” full-color touchscreen, Amazon Alexa integration, Bluetooth disarming, and a built-in camera, these systems are more than just keypads—they’re the smart hubs of your security network. Every system is custom-designed for your Indianapolis home or business and can include door and window sensors, glass break detectors, motion sensors, panic buttons, smoke and heat sensors, and more. Whether you need residential protection or a comprehensive commercial security solution, Nelson Alarm has you covered.
