ADT LLC has over 130 years of service experience and is trusted by some of the most prestigious institutions in the country. ADT monitors every Federal Courthouse in America, as well as 90% of Fortune 500 companies, half of the nation's top banks, and over 70 U.S. airports.

The Basic ADT Monitoring Package

Starting at $36.99 per month, the Basic ADT Monitoring Package includes three door or window sensors, one motion sensor, a yard sign and window decal. This plan uses a landline, which connects directly with ADT in case of an emergency.

The 2-Way Voice ADT Monitoring Package

With 2-Way Voice monitoring, just $42.99 per month, you can communicate directly with a dispatcher via the control panel. The intercom is seven times more sensitive than the average baby monitor, allowing agents to hear you from up to 75 feet away.

The Cell Primary ADT Monitoring Package

For $44.99 per month, you can get the Cell Primary plan, which uses signals from an approved cellular device to communicate with the ADT monitoring center. This package eliminates the fear of the phone line being cut and is ideal for customers without a landline phone.
