I wonder what’s going on there. Did you install them under your Wyze account, or were they installed with your mom’s Wyze account and then shared with you? If it’s the latter, and if your mom has notifications for those cameras enabled, then as a shared user you can’t control the notifications for those cameras. (That’s one of the requests in another Wishlist topic.)
So those are the Cam Floodlight v1s, which use Cam v3s as their cameras, maybe? Is that what you’re saying? That wouldn’t have even occurred to me before, but I appreciate your sharing that nugget to tuck into my brain. I can actually see how that might be useful for someone in a backyard to hear a front doorbell, for instance. Unfortunately, that doesn’t seem like it helps you much in this case. 
Sometimes Cam OG prices are really good from Wyze and Amazon, and I’ve used camelcamelcamel to set free price watch alerts on those (you don’t even have to create an account to do that). I’d consider suggesting Amazon Alexa or Google Home devices for doorbell button press announcements, but support for those has seemed to be spotty for a while. One other thing that comes to mind is a user who DIY’d a portable doorbell chime. You might not need that kind of portability, and I don’t know anything about your physical location or the transformer you’re using to power your Video Doorbell v2, but I imagine you could get an inexpensive chime as described here and wire that into the circuit, if desired.
