My cousin lives in a gated community in Daytona and they have the big iron gates that slide back and forth. It would be nearly impossible to sneak through behind someone. First off the gate doesn't open that wide, I was driving a big suv and it barely fit through the gate. Second, the gate starts to close the instant you pass it. It's nearly impossible to sneak in behind someone unless your on a motorcycle and not too many thieves are on motorcycles. If a big truck needs access they have to come in the day so the gaurd can open the gate to let them in and out. This keeps someone from sneaking in in a Ryder and emptying your place out.
Hope that helps a little.
