I think the only use of the guard is to prevent outsiders from sneaking in and using condo facilities.

I asked her driver, whom worked for her for over 2 decades, why she never buy gcb.
The answer was that she feels condo more secure.
She stays at ardmore area, 5k++sq feet condo, which shows that she definitely have the means, but took a personal choice to stay condo.
Of course, thats not a normal condo.
But then again, when do you hear about burglaries in condos? Almost never.
That's not the point. There are CCTVs so as always it is up to the cops to catch later if they want to.Simi secured? U ish tokking condo or debentures?
Condo security mostly lao ah pek, any taiji they walk oso cannot catch up one.
