Easily upgrade an existing/older alarm system
Gain modern features like smartphone control without changing any part of your older system!
Lose that landline
Our SEM uses a dedicated cellular connection to communicate your alarm system’s signals. No telephone landline is needed anymore! Our SEM’s 3G/LTE transmitter also brings older 2G-based alarm systems up to current cellular network standards.
Have app control
With our SEM, your old alarm system essentially becomes a new one, offering you convenient control and awareness right on your iOS™ and Android™ smartphone or tablet. Our included app lets you remotely arm/disarm your system, receive immediate “push notifications”, and much more!
Make your home “smarter”
Our SEM supports Z-Wave “smart home” devices – like electronic door locks, lights, and thermostats – and it lets you add these devices to your existing alarm system. You’ll even be able to remotely control them through the SEM’s included app!
24/7 monitoring of course!
While our SEM can upgrade your alarm system’s technology, it’s Curtis-Elite’s 24/7 service and local alarm monitoring that keeps you protected. With an SEM you’ll still receive the expertise and support you’re accustomed to from us!
