Hi @schun22! This is an odd concern to hear of as the two devices should certainly work individually and without an issue. Is this garage control in the form of a physical remote control, or an app on your mobile device?
I recommend separating these devices on your home network. If your garage opener is 5 Ghz compatible, it can be moved over to that band while the Camera stays on the 2.4 Ghz frequency. Enabling a guest network on your router and connecting your Camera to it can also help to separate these devices. Feel free to let us know how this goes!
