ADT dealers

ADT Security also has an authorized dealer program. Under this program, independent dealers offer security system installations which are then monitored by ADT. Some ADT Authorized Dealers use similar Honeywell/Ademco products as installed by ADT, while other dealers utilize GE/ITI or DSC products.

Whether a customer purchases ADT monitoring services directly from ADT or through an authorized dealer, a 36-month monitoring contract is required, except in California, where the term is 24 months.

Acquisition of Broadview Security

In mid 2010, Tyco International acquired Brink's Home Security Holdings, (operating as Broadview Security) and merged the company with its ADT brand name in a transaction valued at $2.0 billion. The transaction combined the #1 and #2 security companies in North America, adding Broadview's 1.3 million customer accounts and $565 million in annual recurring revenue.

Legal difficulties

ADT was successfully sued by the U.S. Federal Trade Commission on 2007 for violations of the Telemarketing Consumer Fraud and Abuse Prevention Act and was required to pay $2 million to settle the charges. ADT subsidiaries Alarm King and Direct Security Services were similarly charged and settled for $20,000 and $25,000, respectively.
