In many humorous cartoons we have saw paranoid people who lock their doors to a dozen locks but it usually doesn’t stop their pursuers. The door chain which theoretically doesn’t allow opening the door to a stranger. Although this stranger could stick his hand into the hole and unfasten the chain. Defendius is a system that can protect the stranger or you from opening the door fast. To open it a person need to carry the chain though a maze. It’s quite boring to do each time but what won’t you do for your own safety, right? Besides you’ll learn how to go through the maze very fast.

I can’t help but notice that this chain is longer than a standad chain.
Which would mean that the door can be opened wider…
And would allow for entry by a skinny intruder, such as a juvenile delinquent.
Suggest “parking” the chain on the other side of the maze, making it more taut by removing all of that slack, for increased security.

Does it have to be so big (thats what she said)? A smaller one would still be impossible to solve for an intruder with no vision of the maze if you made it in the right way.

Well, the bigger the maze, the longer the chain. And at some point the door opens wide enough that you just slip some bolt cutters through the crack and cut the chain…

Sure, but you’d better hope your house doesn’t catch on fire!

Your house would be over protected with this door chain. And also it is looking good.
