Get a CCTV camera for it. Make sure it supports ONVIF. An IP camera can be run 100 meters on CAT5.

Trail cams are not intended for remote viewing. They are battery powered and a remote connection would drain the batteries quickly.

Depending on the workload, compression may be an option. You can use zram or zswap to basically get more RAM at the expense of increased CPU usage.

They haven’t been selling anything that cheap since the AI driven hard drive shortage. A refurbished 12TB drive is around $200 now.

The price of DDR4 has tripled over the last year. It’s still not as bad as DDR5 though.

I run one on my firewall, but it’s IPv6 only because of CGNAT. The other one is running on a VPS in case I need IPv4 access. I just configured them manually.

You can get an adapter board that will make it work with an M.2 SSD. I believe it’s only PCIe 2.0, so there’s no point putting a high end SSD in it unless you need a high write endurance. Any SSD will be a huge improvement over a hard drive.

Most Linux distros will run on it since it’s using a 64 bit Intel CPU. If you have the version with 4GB of RAM, you will need something very lightweight though. I would run Debian if I was going to use it as a server or Mint if I was going to use it as a desktop.

The Mac Mini should still be perfectly usable if you put Linux on it and upgrade it to an SSD.

Run an iperf test to see if the ethernet adapter is working correctly. The speed tests on my USB ethernet adapter are almost identical to an integrated one as long as it’s connected to a USB 3 port.

So what happens when the certificate expires? Do you get locked out if you don’t have physical access?

Yes, that’s fine as long as whatever you’re hosting is designed to be safely used on the internet. Just keep it up to date and only expose the stuff you need to. I would suggest setting up fail2ban to block IPs that repeatedly fail to log in though. Depending on what you’re hosting, you may need bot protection, but if all they can see is a login page, they shouldn’t be too much of an issue.

Just make sure you’re not using an EUI64 address. That significantly narrows down the number of addresses per subnet to scan. The bots found one of my computers that was using one. It took them 3 years to find it though.

I use inleed.xyz. It’s free, has IMAP/SMTP access and you can have as many accounts as you want. It’s limited to 1GB of storage shared between all accounts though.

Yes, if you have IPv6, you can open a port in the firewall and have external access. Whatever you are accessing it from must have IPv6 as well though.

Use SSH. Ether open a port in the firewall or connect it to a VPN. If the backups are done on a schedule, you could also setup a cron job on the Pi to send the WoL packet a few minutes ahead of time.

You could use a very low power computer that’s always on like a Raspberry PI Zero W to send the WoL packet to the backup computer. It only uses about 1 watt. Some routers have the ability to send a WoL packet as well.

SFTP or WebDAV would work.

I’ve never had any issues on my phone using Fennec or Firefox. I don’t have many addons installed apart from uBlock Origin. I wouldn’t be surprised if some privacy addons cause issues with Anubis though.

Jellyfin is free open source software, they don’t have the money to provide free proxies to their users.

RAM prices will come down sometime after the AI bubble bursts and they start making more DDR5 again.

Inleed.xyz has free email hosting with IMAP and POP3 access. You can have as many accounts as you want, but there’s a limit of 1GB shared between all of them.
