I have the Wyze V2's in my shop and they're linked to an app on my phone. They broadcast in HD and color, plus have the option to "hear" noise, and you can talk back through the camera to whomever is there. I keep a 32 GB card in them. I've never had any interference issues with my shop door openers, but your mileage may vary. About once every 3-4 months, I might have one that loses connection, but it's rare. The only downfall IMO is that if someone knows it's there, it can be unplugged, so keep that in mind.
