- ADT's Security Detection and Prevention foundation was founded in 1874. Located in Boca Raton, Florida, it used telegraph technologies for security protection. Its first multi-signal protection systems and call boxes became available in the 1890s. In 1909, AT&T bought ADT, allowing it to improve its technologies and expand its business into fire alarms and burglar alarms. ADT went public in 1964 as a part of the Grinell Co. By this point it had monopolized most of the central alarm industry in the United States. ADT was purchased by Tyco in 1997 and has since spread to more than 50 countries.
- ADT has more than 55,000 employees to install and monitor all of its alarm systems. Every burglar alarm is connected with one of ADT's Customer Monitoring Centers. The CMC will know when an alarm is set off. Once the burglar alarm signal is examined and recorded, ADT personnel will respond accordingly. They will investigate the cause of the alarm by first calling the location to avoid a false alarm and then notifying local police or emergency services. Response time is almost always immediate because ADT has seven Customer Monitoring Centers in North America.
- ADT has special burglary alarm systems for homes, small businesses, medium-size and large businesses and for government buildings. Homeowners can purchase a security system for under $100 plus a monthly fee. This basic package includes an ADT SafeWatch QuickConnect security system, alarm monitoring service and other amenities. It also has other more expensive packages for advanced levels of security.
- ADT's advanced systems offer monitoring services for burglary, smoke, fire and carbon monoxide. They have a system battery back-up for power failures and 36-month guaranteed service. Each package includes a wireless control panel, a standard touchpad, door and window sensors, infrared motion detectors, a keychain remote and an ADT Indoor Sounder.
- Investing in ADT burglary alarm systems guarantees state-of-the-art 24/7 monitoring. ADT users get the peace of mind from knowing that they are protected under the most experienced security company in North America. Additionally, many ADT users are eligible for up to 20 percent off their homeowner's insurance up to $500 in theft reimbursement.
