Yeah, it's unlikely that there are cameras in the middle of the forest considering that there was not a single one in the city to spot the White Fang during their robberies with Roman.

I think Qrow may have seen the broken picture and thought that Yang may have tried to go there. Or once he went to the house and saw that they were not there, he uses his "eagle eye" semblance to search from them and finds Yang walking a road a few km away. Kind of like the Byakugan from Naruto but that's just my idea.
