I did exactly this a few months ago on my NextCloud instance. Much sad ensued that evening.

I didn’t know most of these had specific names, and will almost certainly forget them the moment I close this post, but it’s cool to know them for 30 seconds

Having worked on them occasionally was about to confirm that, but somebody gave it more JPEG already and I can’t quite make it out. They do certain look like BNC/some other coaxial connector though and I’ve definitely have to troubleshoot very similar nightmarish setups

Absolutely! I’m disabled and it can take me some time to get to the front door at times, especially in our old 3 story house (mistakes were made). Being able to see who was at the door, and tell them I was on my way down saved me so many missed deliveries.
