Don't rely on the corn to draw the deer.Set it up on a well established deer route so they find it easily.

Set the camera up facing generally North in the winter. I've had some midday shots while facing south that were unfortunately washed out by bright sunshine.

If your camera will take multiple shots per triggering event, use them. Sometimes you might miss the first deer moving thru, but catch others as they come into range - handy during the rut if it's a buck chasing a doe.
