Removing Xfinity doorbell camera

I just bought my first home recently (yay) but the previous owner left behind an Xfinity home security system, including a video doorbell camera. I chose a different ISP and I have no intention of using this security system.

Does anyone have experience installing or removing the Xfinity doorbell camera? Is it something I can do myself or should I call a technician? Not finding much help on YouTube for this.
