They say that it's tight these days, but the only difference I found last month was that luggages were compulsorily passed through the machine. They probably won't detect or won't care about 1 or 2 cameras in the luggage. The securitymen seemed  to be more alert this time, though. One thing that surprised me was the rule to indicate about your personal notebook in your passport at the time of departure from TIA. I somehow managed without that 'tancha' while coming back last week. Anyway, don't know what is that meant for. Seems you cannot change your notebook model.
