Not really applicable to a condo / apartment but we have a moat! (Englishman, castle etc. etc.), members who have visited our place will confirm.
Once past the moat (not seen any crocodiles recently, but there are definitely monitors in there) one then has to climb 2m to the bottom of our 2m wall.
If you try to enter via the gates (which have CCTV) one would have to climb over, they are 2m high too.
Once inside you will be under surveillance by our two deadly rott dober chihuahuas who are very ably backed up by our geese!
Finally Madam has a razor-sharp Malaysian parang! Sadly she also has little spacial awareness so I would likely end up minced along with the remains of any burglars who made it that far!
