If you’re going to run it through duct work, ensure the cable is plenum rated. For Ethernet cable, the jacket will be stamped “CMP”.

The technology worked great, but let me tell you, no amount of regular expressions stands a chance against a 15 year old trying to text the word “penis” onto the Jumbotron.

I don’t trust any of the major phone manufacturers to update my device for an extended time. It is intrinsically against their interest to support a platform long term at the expense of a missed sale on a new device.

Not that I like Motorola, but they do offer an unlocked bootloader on most of their phones. LineageOS supports a number of them officially, which makes for a very easy install and extended support model. Not bad for a $300 phone.

The closest would be the Soyuz 11 disaster. A seal on the re-entry vehicle was damaged when the capsule detached prior to re-entry. Terrible way to go I imagine.

I don’t believe this is true, though I’m certainly no expert on the subject. Taiwan Semiconductor is the largest manufacturer of the chips, but they use lithography equipment manufactured by the Dutch company ASML.

A camera platform small enough to fit a standard door frame isn’t going to be able to hold serious optics. The sensor sizes are going to be too small for good night vision, if nothing else.

The temperature issue is probably an issue of economics. Most people don’t need such a wide range, so off the shelf products don’t support the application, as it would incur additional cost.

Both of these are solvable issues however if you’re willing to use a standard security camera mounted over the door instead. There are many cameras that you could pick with large sensors, heating elements, and more.

Great write-up! This might help some of the bigger instances as well.
