Based on the timestamp (assuming it is around noon), make sure that the cam is facing north or south. What may be happening is the sun shinning right into the "eye" which triggers the camera and it takes a pic, giving you the white picture. My father-in-laws cam was doing the same thing and after some research, we found that if you face it north or south that sun doesn't effect the cam near as much. Give it a try, and if that doesn't help, then take it back and get another one!! Best of luck.
