Coral Acceletor is only needed if you run setup that does not have GPU or enough CPU. Spare laptop usually has enough power to handle AI detection, but RasPi doesn’t. I run mine in CPU at rack server.
Cameras own detections are limited in my experience, and it is much harder to integrate to anything else, like HomeAssistant for notification & automation
I would suggest more learn by doing approach. Learning OSI model etc is nice, but it is quite jargon :)
Use some old PC as a server, and get some network cards into it, and use it as firewall/router. Route your home network/NAT/DNS/DCHP through it. Raspberry Pi’s are nice, but their hw is still bit limited.
OPNSense is quite nice and easy free and open source firewall/router solution.
If you want to add bit of flexibility, you can use some virtualization platform like VMware in to the machine, so that you can run OPNSense in it, with some other virtual servers.
Then when you get things working, you can start looking in to VLAN’s, because they are quite important part of enterprise networking. Most cheap switches nowadays support VLAN’s out of the box.
Combining EV and plugin hybrids together is quite strong indicator that this study has agenda attached.
Plugin hybrids were the most unreliable. Tech wise all hybrids are more closer to gas powered than EV’s. Of course plugin hybrids are more unreliable, you have two engines, so you get issues from both.
Load wise, having the hub separated to own server would make scaling easier. So even one hub and one instance solution for large instances could work. For personal instances this solution would be nice, because they could share one hub, and federate through that.
No one is suggesting here to have any company host the hub.
I am almost 40 also, and game alot. One thing to remember that our generation is the first to actually game their whole life, nes etc made gaming popular.
Older generations haven’t had mainstream gaming, so it is wierd to think people born in 50-60 to game, because games didn’t exist when they were young. We on the other hand have grown with the games.
So I think from ten year on, it will be normal to have LAN parties in your elderly home.
You can add IPS to port to add some security checking, but yes, in general port is never secure or unsecure.
