Can our security door open the cat's eye?

You can see that the cat's eye can be installed on the first floor. I asked the staff of Xinduo door industry that day, and this Xinduo door looks unstable. I haven't closed the house yet. I'm thinking about changing the door. Although I don't have much property, I still can't bear to be stolen. Even if only a cup is stolen, it will hurt my heart, right?
