ADT Monitored Home Security Systems Installed in Los Angeles, CA

For Los Angeles, CA homeowners, we offer a wide array of ADT monitored security systems to choose from. An ADT wireless security system uses your existing home phone line to send the signal to the ADT central station. If you don't have a standard home phone service, you'll want an ADT cellular security system instead. Our newest ADT Command system lets you interact with your mobile device to arm/disarm with secure web access and receive text and email notifications of alarm and device events.

Yelp Review

"Excellent service."

I signed up for ADT via CA Security Pro after a few frustrating experiences with other ADT dealers. Louis was really helpful and honest, Ron did a great job with the install — thorough but quick. CA Security Pro gave me the best overall deal in terms of both quality of service and cost. Highly recommended!
