Does the L5100 need to have an internet connection?
All it needs to communicate with central station is a standard, copper-wire phone line. However, installing an internet communicator, like the iLP5, has become a popular choice because it allows the system to work with Honeywell's Total Connect service. Adding a cellular communicator, like the GSMVLP5-4G, will help your system qualify for Total Connect while also creating a more reliable line of communication with central station. For users who want superior backup communication, both an internet and a cellular communicator can be installed to achieve ultra-reliable, dual-path communication with the central monitoring station.
