What's the difference between a neutral zone infraction and offsides in football?

In football, a neutral zone infraction occurs when a defensive player moves into the neutral zone before the ball is snapped, causing the offense to react. Offsides, on the other hand, happens when a player crosses the line of scrimmage before the ball is snapped. Both result in penalties, but offsides is typically called on the offense and neutral zone infraction on the defense.
