Don’t have a landline telephone? No need to worry, this premium home security package is tailor made for you. The plan features the all-new CellGuard® Technology, which allows you to make use of cellular technology to communicate with an ADT monitoring center, and is also completely wireless. While many systems are dependent on your landline connection, CellGuard allows you to protect your loved ones even if your landline connection is disconnected or if you’ve lost it during a construction or a storm.
