For over 125 years, we’ve made protecting and connecting the centerpiece of what we do.
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 neighbourhood, creating the first residential security system network.
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.
ADT’s first president
Robert C. Clowry was ADT’s first president. He was also a colonel in the US military. He worked his way up from messenger boy, eventually serving as president of both Western Union and ADT which he led for eight years.
Central monitoring centres
ADT pioneered the concept of the central monitoring centre, enabling thousands of customers to link to 24/7/365 monitoring and protection.
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 providing immediate response to fire.
Secured by ADT
A new ADT security feature gained immediate customer approval: the iconic ADT yard sign which now dots thousands of yards across the country.
In July 2014, ADT purchased Reliance Protectron Inc., at the time Canada’s second-largest security services provider with 400,000 customers from coast to coast.
ADT Interactive Services
ADT elevated home intelligence when it launched Interactive Services, the app that lets customers remotely access and control their home security system, as well as lighting, climate control, video surveillance and much more..
