ADT has launched a new DIY home security system called ADT Blu with individual cameras and entire systems that can be installed easily.

For hard-wired setups, installers run wires through the home to each device and sensor, including all door, window and motion sensors. The technician will walk you through how to use your ADT home ...

Door sensors detect door position (i.e., open or closed) based on the precise gap between the magnet and the reed switch.

The Starter package, intended for DIY installation, comes with the ADT hub, four entry sensors, two motion detectors, one Google Nest doorbell, an ADT yard sign, and four ADT window stickers.
