What if the property balcony is not allowed to install invisible security window?

Hello, you should have signed an agreement with the property when you checked in, or you can read the owner's manual, which should be comprehensive. If it is stipulated that security window can't install it, if you sign it, don't install it.

Or security window can be installed inside the window without affecting the overall beauty of the building. If you are in a high-risk area, you can sign another contract with the property, and the property will take full responsibility for the losses.
