I bought a home in Nov. 2017 and had Xfinity Internet and TV, Phone installed but not security because the wanted me to have the monitoring. Home has Xfinity security motion and window sensors and keypad already in the home. I know the previous owner had xfinity security and i saw the router in the home before i bought it but it is not here now but everything else is here. My question is I have the equiptment already in the house and would like to have it working but i dont want the monitoring. I own it just would like to use it if i chose to. I have read that there is a router that talks to the sensors. What is it and how does it work. Is there a way for me to just buy there router either from them or someone else and what would that be, make the security system work when i want it to with no monitoring.
