Recently had a security system added. At the time, a techician installed the equipment and told me that I could add more sensors, cameras, etc. if I wanted to.
I do want to but don't know how to pair the new equipment to my system. I contacted xfinity who told me that since it was installed by xfinity, I would have to have xfinity add the sensors.
Does anyone have advice or a way to do this without having another tech come out?
