It is not save as there is a risk somebody takes it.
How big is the risk? Can't tell as I don't know the condo management, the people who visit the place and the security.
"How about CCTV?" What you want to know, what condo are you talking about?
Do they have CCTV?
Will the CCTV work if they have it?
If it is there and it works, will the staff show it to you?
What if it is the staff that took it?
