I have setup and used the PTZ Optics 20X SDI/HDMI cameras in 7 bldgs
https://www.amazon.com//dp/B01BI7BQBU. They are expensive ($1600), but I have also purchased them on ebay for much less. An identical twin camera by Prisual
https://www.amazon.com/dp/B097CF8482can be purchased on Amazon for $600. A close cousin camera by FoMako
https://www.amazon.com/dp/B08L5GW5Q1is also on Amazon. The nice thing about these cameras is the ability to stream directly from the camera to youtube. Free camera control software from PtzOptics works on all of them.
In some bldgs the cameras are wall mounted, while other bldgs bring the camera out each Sunday and setup on a tripod. In both cases the audio is routed (in attic or taped along side wall of chapel) to the camera with a 100ft stereo headphone extension cable that is permanently plugged into the chapel record output jack. If running audio cable isn't possible then you can use a wireless audio conection like this
https://www.amazon.com/dp/B09MCGQ8S2. The audio receiver can get it's power from the USB port of the camera.
In two bldgs we completely automated the sacrament meeting broadcasts by using a 24/7 timer relay
https://www.amazon.com/gp/product/B073DGGHD7 to turn on/off the camera's POE power for each sacrament meeting. As soon as the camera is turned on it starts streaming to youtube. The audio is automatically switched off during the sacrament ordinance when the camera is panned 90degrees to the side via a magnetic switch that is attached to the side of the camera (see attached picture for better explanation). The bishopric uses the IR remote control to select one of several preset positions (pulpit, piano, choir, sacrament ordinance with audio-off, etc). Recently we ran a second audio cable from the organ to the camera, bypassing the magnetic audio off switch at camera, so the organ prelude, sacrament hymn, and postlude can be heard at all times, even when the sound system is off.

For the last 2 years we have allowed anyone to watch the streams just by going to our stake website hosted on a free google "site" and clicking on a youtube link. Starting this month we were asked to limit access to the streams, so now when the member clicks on the button to watch the stream, a Google Form will popup. The member must enter their name and a pincode unique to their ward that they received from their Bishop, afterwhich the streams can be watched. Google Forms automatically logs the time, member name, & pincode to a Google spreadsheet each time the stream is accessed.
