Uquiquiti Media Converter works only with Obsolete Passive PoE

Tue Nov 12 08:19:10 EST 2024

The Ubiquiti F-POE-G2 Optical Data Transport media converter only works with obsolete passive PoE. It cannot be powered by any standards based 802.3 PoE. It is a good price but don't expect it work work with modern PoE.

This Media Converter from Amazon does work with modern PoE. It has only been in service a couple days but so far so good. It is a nice small package. It does get quiet warm. It was mounted to a vertical service with a 3/4" PVC conduit strap. Probably a good idea to put a small spacer under it to maximize airflow on all sides.

In four years I hope to read this linked essay again to see how it holds up. Heather Cox Richardson writes calm, well-thought-out "letters" almost daily. This one summarizes the 2024 Presidential Election here in the United States. Hopefully the next four years will actually improve things for all Americans.

UniFi Protect Reduces Resolution of Snapshots

Mon Sep 23 17:03:26 EDT 2024

• UniFi Protect snapshot resolution was reduced recently by Ubiquiti "to free up resources for new features".
• http://camera_IP/snap.jpeg used to return a full resolution image but now its dramatically reduced resolution.
• From a full size browser, in playback mode, a snapshot of a live view saves a low resolution image. A snapshot from 10 seconds before live is saved in full resolution.
• From the iOS app, in playback mode, a snapshot of a live view saves a full resolution image to the photos app. Why does a full browser save low resolution.

Workaround

• Here is a high resolution snapshot workaround but it can be slow retrieving the image.

• ffmpeg_path =  # file path to the ffmpeg binary
  cam_link = # rtsp camera URL from Protect advanced settings
  output_image_file = # file path to receive still image
          
  $ffmpeg_path -y \
      -loglevel error \
      -rtsp_transport tcp -i ${cam_link} -frames:v 1 \
      -update 1 ${output_image_file}

Tesla Model Y Bolt Rolling Under Floor

After a Tesla service for a computer failure and driver mirror trim issue, we noticed what sounded like an object rolling around under the floor when the car accelerated, decelerated or turned. After months of that aggrevation we finally decided to try to solve it. With the help of a cheap WiFi borescope, we saw a bolt in the air duct under the driver's seat. It was about 18" into the duct. We retrieved the bolt with a magnet taped to the end of a wire and finally, no more rolling sounds.

We were glad to resolve the issue because Telsa said they would have to charge hours of work to remove the front seat and floor covering to search for the sound. We have since ordered grilles to cover those air ducts to hopefully prevent any future items from sliding down the duct.

Conservative Judge J. Michael Luttig to vote for Harris in 2024 Presidential Election

Mon Aug 19 18:45:02 EDT 2024

Judge J. Michael Luttig writes an essay about the 2024 Presidential Election.

Excerpt: "We Americans know all too well what has come before. We understand what the political class does not want us to understand. That in the presidential election of 2024, the candidates’ policy differences are the least that matters to the United States of America."

Excerpt: "Thomas Jefferson agreed with Alexander Hamilton about very little, except about the existential danger to the Republic of a populist demagogue. "If once elected, and at a second or third election outvoted by one or two votes, he will pretend false votes, foul play, hold possession of the reins of government, be supported by the States voting for him," Jefferson presciently wrote to James Madison in 1787."
