Founded on Aug. 14, 1874, we've made protecting and connecting the centerpiece of what we do for more than 145 years.
ADT Solar Rises
ADT moves beyond safety and security with the introduction of ADT Solar. Available in more than 20 U.S. states at launch, ADT customers can add sustainable energy generation and storage to their safe and smart homes and businesses.
Command and Control
ADT continues driving innovation with the launch of ADT Command and Control. The ADT Command panel is equipped with smart home capabilities that help customers protect and automate their homes through one easy-to-use interface. With the ADT Control mobile app, customers can remotely access their connected smart devices including lights, locks and thermostats to setup schedules, scenes and geofences for a fully automated connected home experience.
Creating Customers For Life
Much has changed since our humble beginnings in 1874. One thing that hasn’t is our desire to constantly improve. So we combined forces with Protection 1 to further raise our standards for customer security and service. Together, we serve over 6 million customers with more than 17,000 employees in over 200 locations in the United States.
ADT elevated home intelligence when it launched Pulse, the app that lets customers remotely access and control their home security system, as well as lighting, climate control, security cameras and much more – all in real-time.
Secured by ADT
A new ADT security feature gained immediate customer approval: the iconic ADT yard sign, which now dots millions of customers’ yards across the country.
The First Burglar System
ADT started its first big expansion in the 1940s after pioneering the first automated burglar system. At the same time, ADT installed the first automated fire alarm system, enabling immediate response to fire.
Central Monitoring Centers
ADT pioneered the concept of the Central Monitoring Center, enabling thousands of customers to link to 24/7/365 monitoring and protection.
Stellar Early Leadership
ADT grew strongly and steadily under the guidance of its high-profile early leadership. Thomas T. Eckert, who led the Telegraph Office during the Civil War and was close to President Lincoln, was one of ADT's early presidents. He was followed soon after by Robert C. Clowry, a colonel in the U.S. military who worked his way up from messenger boy to eventually serve as president of both Western Union and ADT, which he led for eight years.
ADT introduced the first proactive security monitoring and response service, employing "Roundsmen" to make rounds each night of customers’ homes to help prevent crime before it happened.
First Security System Network
It all started on April 5, 1874, with a nighttime break-in. American District Telegraph (ADT) Founder Edward Callahan created a telegraph-based "call-box" to signal for assistance to a central office. He quickly connected 50 other homes in the neighborhood, creating the first residential security system network. American District Telegraph was incorporated shortly thereafter on Aug. 14, 1874 in Baltimore.
