Our home security systems are best known for monitoring against burglary and fire, but we also offer CO monitoring and flood detection, which can help with storm preparedness thanks to a water detection sensor.

Beyond our basic security, you should also look into our ADT Pulse® products. These include controls for lights, locks, live video, as well as remote temperature control, all accessible from our app.

ADT is the #1 security company in the US, but we also have a line of products for families specifically concerned about senior safety. Our three Medical Alert System options use medical bracelets and other medical alert devices to connect senior citizens directly to a support team that can send help immediately if anything happens.
