...ultimately would you trust your home to something you can throw together in a few weekends?

With respect to the massive engineering effort, and acknowledging you probably didn't even realize you were doing so, I have to point out that this is an example of the extremely distasteful emotional manipulation too often used by security-related companies, and it needs to stop. Advertisements with lines of the form, "Would you trust your family's safety with anything less," or, "Nothing is too good for your children's safety," contribute to the general paranoia of society, not to mention the gross misallocation of capital based on manipulation instead of merit.

I'm the last person you'll hear using the "but think of the children!" tactic. American paranoia has been exploited for nefarious purposes long enough (I'm glad to say, I'd be surprised if you found any such message in the Nest Cam advertising campaign.)

Politics aside... it's your prerogative to buy or build any system you want. I was just clarifying why, in my personal opinion, if you really have a need for a security system, choosing a hobbyist project over a system built by a team of professionals is probably a bad idea (again, look for the article I linked before about how easy it is to "hack" into streaming baby monitors.)
