I have a different vibration pattern for my wife's calls and messages, work calls and messages, and all others. I swear I will get phantom vibrations from a specific set randomly.
For indoor cameras, I use TP-Link tapo wireless cameras, and hikvision for outdoor. I put all of them on an isolated camera wlan and vlan without internet. the tapos work fine without internet access, but the status light will always be orange as it tries to reach some tplink aws IP to verify connectivity.
typically you only need one power supply to run it, once you move to redundant power you can use the second one in case the first one fails. when you plug both in it will just balance across both until one fails.
in my opinion, hardware should only be hypervisors that run virtual machines, then you can provision VMs, similar to using VPSs. going this route you will need a vga monitor for initial setup, eventually everything is done over the lan with a web ui or ssh.
i use proxmox which is Debian based for the hypervisor.
As far as what you do with it, is that you can in theory replace the VPSs or test software in your lan.
to compare, i have my router (vyos), homeassistant, a docker server for hosting small services, a network lab (gns3), windows and mac VMs, and more running on a cluster that is using similar hardware.
the article does mention situations where police and military would see benefit from magazine disconnect, but obviously if the gun industry wants something, like to not install the disconnect, police and military will do whatever they can to make that happen
to take this a step further, imagine someone who has been exposed to these services designed to be addictive their entire (digital) life, as well as being pushed further into these services by their peers who are equally addicted and the "influencers" they look up to that are paid by these services.
it's interesting because as he adds cabinet picks, they come with allegations, as well as allegations stacking against those already selected. must be a requirement for the job, typically i would think this would make security clearance all but impossible due to the blackmail but maybe that is what he liked about these picks. that or trump just sees those like him and gravitates towards that, since his drug and dementia addled brain can't handle anything else.
i have used gate for my internal and external, works very well and i do exactly what you are asking and separate different versions and modpacks by name
