The cameras are sealed and a set of batteries last around 3 months. There are cameras with cell connection but that gets pretty expensive and doesn’t work in remote areas.
Cold emails and calls, networking mostly. Get some business cards, hand them out freely and include it as part of your pitch if the audience is a right fit (person or small group of persons). Email in profile if you want to discuss further.
How do you know this is the right job for you if you've just started at it? How do you know that you won't be bored at this job or you won't be cleaning others' mess, after a few days/months (No pun intended).
I vetted the company by talking with a friend who works there and by being mindful throughout the interviewing process. So I have a reasonable expectation. I had other great offers and I've worked in a lot of different kinds of companies so I know how to look and what to look for now.
Of course, there could also be a quagmire of corporate politics and sloth that won't get revealed for months. If that happens, I'll reevaluate periodically and open the door to change.
Even in the best case, I don't expect I'll work there for the rest of my life. 5 or 10 years would be fine and all I look for right now.

I think the crux is learning about yourself and what you want out of a job, and out of life. That takes time, it's a nonlinear process, and it's non-deterministic too. Make mistakes (embrace them, not fear them), be prepared for change (keep a few month's worth of cash in the bank), follow your dreams, and do the things you love as much as possible.
And try everything. Live life to it's fullest.
