The new house is on the second floor, and the property requires no anti-theft cage. Is it safe as long as you don't use tempered glass? Bad guys break tempered glass easily?

The new house is on the second floor, and the property requires no anti-theft cage. I think the property requirements are reasonable. Now tempered glass is very anti-theft, and bad people will not break it easily, because people will break it everywhere to steal it. It's too big to do this at all, don't worry.
