Take this with a major grain of salt as I don’t know much about this.
I think that a router isn’t always also a wireless access point. It could just be for wired connections like a switch.
Please downvote and correct me if I’m wrong, I really know little about this.
I’ve used an Arlo camera system and it did NOT play well with homeassistant. Requiring an account, certain features behind paywall, I really can’t recommend it. Maybe things have changed (or maybe some of it was user error) though.
Even though I don’t agree with some of the points, I would still hope to see discussion rather than unexplained downvotes.
