I'm looking to buy some security cameras for my mother in law. I currently have a small server with plenty of storage at my place that I'd prefer to use on at least a temporary basis to keep costs down. Are there any self hostable cameras that support a built in VPN? I currently use tailscale for my network but I'm open to learning something else. Alternatively, can they run over a tailscale subnet router? I don't use that yet but if I could place a cheap node in her place to help her access footage and my other services via subnet routing I'll do that too.
