Start by learning about how internet businesses run. Then start figuring out:
What type of hosting and bandwidth is involved - and how much does it cost? What legal hoops does RLC have to jump through to broadcast? What is the business model - financing, target audience, etc? How does RLC differentiate itself from other voyeur webcams? What incentives does RLC offer to tenants to get them to perform in a way that's interesting? Etc, etc. Put your basic business model down in a Word document, then start doing the financial modeling in an Excel spreadsheet. If you're really interested in figuring it out, the information is out there on the web. But running a business like RLC and making a profit is by no means simple. I have a decent knowledge of how omnichannel retail works - RLC is a pretty slick operation.

Running any business is complex. RLC starts with a big hit against it - the abundance of free porn on the interweb. And it's got the problem of finding couples who are willing (at a minimum) to be seen nude - and at worst - having sex. I would imagine the supply is needed. As the rest it's money in v costs. I'm guessing the apartments are located in low cost parts of the world: ditto a lot of the attraction for the occupants is free food and lodgings.
 
RLC has apparently been going for several years now, so they've got something right. The questions is whether they can improve on what they're doing and whether they're making enough profit to do so. 

You could work it out by looking at the thumbnails with premium access. The girls that get the most attention are (in order):

Girls under shower Sex Cameras showing girls likely to take part in (1) or (2)

They may also be getting to grips with the idea that nothing in the apartment is private - and that the cameras in the bathroom are fairly popular...
