how to remove old sensors and 2GIG control panel before installing Ring products

I’m using protection 1 home security system. Now I want to change to Ring. How do I uninstall old sensors and 2GIG control Panel in order to replace Ring security kit? The sensors are stick on doors and windows.

Hi @xue. For this concern, it would be best to contact the company that installed this system for you. If they are not available, I would search for a licensed electrician in your area who can safely perform this task. Without knowing how this system is installed and what is involved, this is my best advice. I hope this helps!
