These are live feeds from cameras near the pier in Pacifica, CA. The first three cameras are from my system and are being streamed via YouTube. These three camera streams have the following features:
If you prefer a triptych-style display (3 camera views arranged all in a row), there's a different version of this page here: Sharp Park Beach Triptych.
NOTE:It appears that if no one is viewing for some period of time, youtube shuts down its encoder. It will start again as soon as someone starts watching, but there is a 20-30sec delay. So if you start watching, and the timecode in the upper left is more than about a minute from the current time, just wait 20-30sec, you should soon see it jump to the current time.
There are a few more notes and tips at the bottom of this page.David Chamberlin firstname.lastname@example.org
These tips are primarily targeted at the first three videos, as they use youtube's livestream capabilities. The fourth video (North Side of Pier) uses Nest which has differerent controls and capabilities.
The first three videos are part of a multi-camera stream. If you view any of those three streams, you have the ability to switch to the other cameras within Youtube. Note that Youtube currently only supports this when viewing in a web browser. You will not have the option to switch streams if you are viewing on a mobile device or TV. If you look at the image above, to the left of YouTube you will see a box with arrows in it. If you click on that it will bring up the available views and you can click on whichever view you want.
As noted at the top, if no one has been watching the video for a while, youtube will shut down its encoder. Once someone starts watching, the encoder will be restarted. However there is a 20-30 second delay. During this 20-30 second period, youtube will show the last 20-30 seconds that were recorded before the encoder was shut down. So if you look at the timecode in the video in the upper left and see that it's more than a minute or two old, just wait about 20-30sec and you should see it jump to the live feed.
You might also be "off live" if you hit pause, or did something to jump back in the stream. To tell if you're at the live point, you can look to see if there is a red dot next to "LIVE" in the youtube control area. If you hover your mouse over the video, you should see something that looks like this at the bottom:
You can see in the image above there is a red dot next to LIVE. This means it's at the live point. If it's grey, then you're behind live. You can just click on LIVE and it will jump you to the live point.
In the image above you will also see a red line. This is the timeline. You can go backwards up to 12 hours. If you click on the red line you can jump backward to a particular time in the stream. As noted earlier, if you want to get back to the live point, just click on LIVE.
If you click on YouTube in the control section, it will open the video in YouTube, which will give you the normal controls and abilities you have when watching youtube videos (including sharing and "casting" it to a TV or other device).
To the left of YouTube, there is a gear icon. This lets you choose the resolution. It defaults to Auto.
To the right of YouTube, there is a square. If you click the square, you can view the video full screen.
If you don't want to hear the audio, just click on the speaker in the control area.
The first three cameras (view of the pier from the south, view of the beach and view of Mori Point) are Ubiquiti G4Pro cameras. They capture in 4K resolution. The compression levels are fairly high, so you don't always get the full benefit of 4K resolution, but it's still pretty good. If you view it full screen on a nice TV/monitor you can make out quite a bit of detail. They are mounted on one of my antenna masts, so they are completely exposed to the elements. We'll see how well they fair, and how often I'm going to have to clean the lenses. If it ends up being too bad, I'll probably mount them under the eaves of my roof to give at least some protection. UPDATE:The cameras have been fairing better than I expected. The only issue comes when there is a strong West/NorthWest wind and large surf, as that kicks a lot of salt in the air. There isn't much that can be done about that except for me to go out and clean the lenses. So if it's blurry, you may just need to wait for me to clean the lenses.
The three Ubiquiti cameras record locally (in my house) to a network video recorder (the Ubiquiti CloudKey Gen2 Plus). This gives me the capability to go back 2-3 weeks. To get this system to work with youtube's livestream capabilities, I use ffmpeg to take the rtsp stream from the CloudKey and push it to youtube using rtmp. Probably more details than you wanted/needed.
The fourth camera is a neighbor's camera, so I don't have many details on it other than it's a Nest camera and uses the Nest streaming capabilities.
