Hello @user_bewi8w, thank you for taking the time to leave a post.  To make sure we fully understand your concern, could you share a bit more detail about what you’re experiencing or what you’re trying to do? This will help us provide the most accurate support.
Just to clarify how the system works: Our cable boxes can be used to access certain Xfinity Home Security features. Through the Xfinity Voice Remote, you’re able to use commands like "Arm my system" or "Show my Xfinity Home cameras." However, the cable box itself is not the primary control device for the Xfinity Home Security system; it simply offers an additional way to view or manage features. For Xfinity Home Security to function properly, the main requirement is a high‑speed internet connection with a minimum recommended speed of 750 Kbps (0.75 Mbps) upload/download. Once we have a better understanding of your specific question or issue, we’ll be happy to help further.
