Already have an alarm system?
Upgrade your security.
You may not need to start over.
In some installations, we can reuse existing equipment—including sensors and wiring from a wired alarm system. We inspect what you have before recommending what to keep or replace.
Upgrade a compatible panel
An Alarm.com System Enhancement Module (SEM) can modernize selected existing panels with remote access and connected features, without replacing the entire system.
About Alarm.com SEM ↗Not every system qualifies. We verify model, firmware, condition, programming access, power and service compatibility. Smoke and CO devices need a separate assessment; reuse is never assumed. Remote functions and monitoring require the appropriate active plan.

What to know before choosing
Not a carbon-monoxide detector. Required alarm placement and monitoring services must be assessed separately; this is not a substitute for a complete life-safety plan.
Manufacturer detailsCan I use my phone?
With compatible equipment and an active Alarm.com service plan, you can control your system and receive selected notifications through the app. Features depend on the equipment and plan.
Can you work with my existing equipment?
We inspect the panel, sensor types, condition and communication options first. Some parts may be reusable; not every device can be carried over.
