Wireless is doable, I'm doing it.  
I have a wireless bridge to my detached garage (similar distance) and I'm streaming 4 1080p cams at 15pfs and 8192 bitrate with zero drops.  With my current cam settings I stream a constant 28 megs a crossed it, plus the back half of the garage is a guest room and I serve streaming tv and xbox to my son who's currently staying in it.  I can push about 150 megs on that link if I need to.  These are 2 mikrotik routers (indoor) bridged together.  Not an endorcement tho, they are not user friendly.
I do this for a living though and would be hesitant to suggest others do it.  It takes an 80 meg wide 802.11 AC channel and I live in a remote location with zero interference.  If you do go this route I would suggest using a wireless bridge that is separate from the wifi though.  Many are on the market.  Out door bridges would be better for a cleaner signal.  Ubiquiti makes plenty of stuff to choose from.
So yes it's doable, BUT if a cable is even remotely an option... do that.
