Ugreen power supply fits 1U

I built this rack for my product demos and home assistant demos. I organized a few home assistant meetups (50, 150 people).

But I am rebuilding because the GL.iNet berryl ax is replacing the Fritzbox.

I need to power the following:

- router 5V

- Home assistant blue 12V

- Odroid H2 15 V

- Switch 9V

- various other USB devices

- Gaming PC (is still powered by a Pico PSU)

So I went out and found this handy ugreen power supply. 8 ports and 200 Watts

I could not find any dimensions. Some brands are just annoying. So I ordered it and it looks like a good fit for 1U.

I also ordere a couple of cables which terminate to barrel jacks and have specific voltages for the devices.

Just had time to test it for 5 minutest and worked great!

I hope it does not disconnect power when I unplug and plug in new stuff.

I need to test that later.

When this works I will also create a 3D 1U mounting bracket.

Anybody have experience whit that particular unit?

I have a request for a weird use case. A picture is worth a thousand words:

You are looking down a street. Left side, a cafe, where the camera is installed.
Right side is a bench where people can sit down and take a photo via a buzzer.
That buzzer and software part is basically taken care of.
However, I am missing a good camera.

I tried the Reolink E1 Zoom, but the distance of 8 meters plus the (assuming) wide-angle lens doesn't work that great for a group photo.

The camera is behind a window. So no problem with outdoor things.
Ideally, it is connected via WiFi or the Raspberry Pi/ESP32 connected via USB to that camera, which is connected to WiFi on the RIGHT building.

I have found CCAPI from Canon.
Would that be a good option?
If yes, which camera would be suitable?
No stream needed, only photo.
Can the camera sleep, and can we be woken up via CCAPI? AI says yes, but I won't trust it until someone with experience can tell me that.
I have no clue about cameras at the moment.
