Can ADT work without Wi-Fi?
Choosing to set up your system to communicate through your cell phone service rather than a landline still doesn't require you to have an internet connection. This is unique to ADT as most other in-home security systems rely on Wi-Fi for devices to both talk to each other and work with the central keypad unit.
