More detailed notes on swift activity are in the 2021 Swift diary.
Here is a page with some explanation of how I do the video.

Please see the notes below.
This is nestbox #1 in which swifts raised young each year from 2012 to 2020.
In 2021, the first swift returned on 2021-May-7, and was joined by a second on 2021-May-11, though there were times after that with just one, or none at all. Only by around 2021-Jun-10 did there appear to be a pair settled here. An egg was first sighted on 2021-Jun-17, but could have been there (not in the nest) earlier. A second egg was laid on 2021-Jun-19, and a third on 2021-Jun-21. The first egg hatched on 2021-Jul-14, and the second by the next day. The third egg didn't hatch. Fledging is expected around 2021-Aug-25.
The static picture from 2015 shows two adult swifts and their three young.
This is nestbox #4 in which swifts raised young each year from 2014 to 2020.
In 2021, the first swift returned on 2021-May-9, and was joined by a second on 2021-May-12. A first egg was laid on 2021-Jun-5, but was removed and broken by a swift the next day. There wasn't always a pair present overnight, and only by around 2021-Jun-10 did there appear to be a pair settled here again. This pair laid a first egg on 2021-Jun-17, and a second on 2021-Jun-19. The first egg hatched on 2021-Jul-7, and the second by the next day. Fledging is expected around 2021-Aug-18.
The static picture from 2016 shows both adult swifts at the nest.
This is 'starling' nestbox #sb2 in which swifts raised young each year from 2018 to 2020.
I haven't had video from this nest since 2019.
The static picture from 2018 shows two chicks in the nest. The live video view is looking directly downwards. The 'front' of the nestbox is to the left (as opposed to lower-right in the static image) and a piece of rough wood is fixed on this side from the floor up to the entrance hole which is just off the image at left. The swifts climb the wood to reach the hole. See here in the 2018 diary for a photo of the outside of the box, and a description of it.
I don't guarantee that the video will remain online, or will be working at any given time, so try later if it doesn't work. Please don't leave the live video running for extended periods, especially if you're not actually watching it. You can close it (and return to the static image) without leaving the page by clicking the [x] at top-right of the video, or by hitting 'q' (while over the video). Hit 'f' while over the video for full-screen, or use the icon. Clicking the video (or spacebar) will pause or re-start it.
There might be audio as well as video.
