Frequently asked questions

Who is ADT?

ADT Monitoring is the only security company that has provided alarm monitoring services 24 hours a day, 365 days a year, for well over a century.

Unlike home security companies with just one or two monitoring centers, ADT operates six nationwide customer monitoring centers. Even if a natural disaster or other issue disrupts one ADT monitoring center, the others can easily handle the overflow and help you in a crisis.

ADT understands your family’s needs are unique and you want choices when it comes to home security. That’s why ADT offers three different ADT monitoring packages.

Why do I need a security system?

In the US, a home burglary occurs every 25.7 seconds, costing victims $2,799 per household on average. Combined, victims lose $3.4 billion annually.1 On top of monetary loss, victims often face the emotional distress of losing sentimental items and having someone violate their space.

With a home security system, you can arm windows and doors with burglar alarms that scare off intruders and alert monitoring centers and first responders. With an even more advanced camera system, you even may get concrete evidence that helps police identify offenders.

Whether your priority is your belongings or your daily sense of safety, security systems can help you feel comfortable at home.

If I lose power, will my security system still work?

Yes. Your ADT monitored security system has a backup battery to prevent it from shutting off in the event of a power outage. The battery runs for up to 24 hours after an outage occurs.

How much do ADT monitored security packages cost?

ADT-monitored home security plans provide high-level surveillance and home automation features starting at $36.99 per month. ADT installation costs between $99 and $199. Your ADT security cost includes 24/7 monitoring, remote connectivity, instant alerts, and constant support from a professional team of specialists and emergency personnel—all for a price you can afford.

ADT offers three exclusive ADT monitored security packages: Complete Monitoring, Remote Monitoring with Command, and Video and Home Automation with Command.
