As long as you have room for the door to swing it can open either direction. You just have to buy a pre-hung inswing or outswing door to install. A cheaper option is get a wireless outside webcam and install it out of reach but in plain sight. Set it to email you pictures anytime it detects movement. If they want to break in after that the door wouldn't have made any difference.
While your at it go onto eBay and buy some ADT stickers and signs. The best option is to make sure they don't want to mess with you in the first place rather then invite attack and plan a defense against it.
The best defense is a good offense! -- IF YOU FIND ANY MISTAKES IN MY WORK...Please consider that they are there for a purpose. I try to please everyone and there is always someone looking for mistakes!
