For people who can’t or don’t want to run a VPN app, Tailscale has the Funnel feature, which can… Funnel traffic into your Tailscale net.

I’ve only used it for light stuff so not sure how well it will work for video.

There are other Mesh VPN solutions out there - I’ve used Hamachi for close to 20 years on Windows, and it just works. There’s a Linux client too, though I haven’t worked with it in years.

Alternatively, you can setup a Raspberry Pi just for the Tailscale/Wireguard VPN, for say at your parents/friends houses. Cheap, simple solution, and it’ll handle DNS for the devices in the Tailscale mesh. This is something I’m doing for family/friends for unrelated/slightly related reasons (I’m reproducing the Backup to Friends feature that Crashplan used to have, so all of us can have multiple backups in our own “cloud”) , but they’ll get the side benefit of video, which won’t get backed up, just duplicated everywhere.
