How much does an ADT security system cost?

Pricing depends on the size of your home and equipment selected. Call for a free, no-obligation custom quote.

How fast can I get my system installed?

In most California cities we offer next-day or same-week professional installation. Our certified technicians typically complete a full home setup in 2–4 hours.

Is California Security Pro the same as ADT?

We are the #1 ADT Authorized Dealer in California. That means you get the exact same ADT-monitored equipment and 6 powerful monitoring centers, installed by a local team that knows California neighborhoods.

Do I need a landline or internet for monitoring?

No landline required. All modern ADT systems use cellular and dual-path monitoring, so you stay protected even during power or internet outages.

Can I control everything from my phone?

Yes, the ADT+ app lets you arm/disarm the system, view live cameras, lock doors, control lights, and get instant alerts from anywhere in the world.
