Flush mounted boxes not aligned with exterior facade

We had the electrician install power for outdoor cameras. The flush-mounted boxes now protrude several centimeters above the plaster. Is that normal? How are you supposed to attach an outdoor camera or a cover to that without it looking totally stupid? What do you think?

What does the electrician say about that?

You have photographed a work in progress. When it is finished, it will look different.

What do you have to install if you want to run network cables there? Those are just flush-mounted boxes, right?

What do you leave in place if you want to have network cables pulled there? Aren't those just flush-mounted boxes then?

The answers are probably as diverse as the cases themselves. We see a plaster facade, we do not see whether it is ETICS. The network can be PoE or power supply separately. We do not know what weight and wind load the cameras bring – this also determines whether the boxes are just space for cables or should also integrate a mounting bracket function.
