Connecting and actually setting up this device was complicated for me but this system is backed by excellent online support. Called the number provided and was helped by an agent named Michael who was very helpful, patient really knows this system well. Guided me through and was able to set it up with his help. I decided to take a chance and called back next day to set up an older model that runs with an App on your phone. This older system had failed when my office Wifi was changed. I found this system was less complicated and another execellent agent named Isaac guided me through the reconnection of this old discontinued model of NGTeco (KF 460) and it started working as well. My hearty thanks to Isaac and Michael for your excellent support and professionalism. Both of the NGTeco products are great. Great value in these NGTeco products.
