While our system communicates wirelessly and is not hard-wired into your electrical system, there are still some minimal wires involved. Specifically, the AC adapter or POE ethernet cord for power, the speaker cable that runs to the VNS2210 controller on some styles of speakers, and the cables that connect the base station, transmitter, and antenna together. However, since none of the system is hard-wired, you can easily move, add, or remove products as needed.
