Given that the center of an ellipse is at the origin, the focus is on the $x$-axis, and the eccentricity $e= \frac { \sqrt {2}}{2}$, the area of the quadrilateral formed by connecting the four vertices of the ellipse in order is $2 \sqrt {2}$.
(1) Find the standard equation of the ellipse;
(2) Given that line $l$ intersects the ellipse at points $M$ and $N$, and $O$ is the origin. If point $O$ is on the circle with $MN$ as the diameter, find the distance from point $O$ to line $l$.
