Reminds me of my condominium in Ho Chi Minh City where
all the video intercoms/door controls are installed in locations in the various apartment designs where maximum viewability of the apartment can be achieved. Mind you, this requires the control units being installed in some very inconvenient or unusual places and are a damn nuisance to work furniture layouts or access around.
I 'modified' my unit by pulling the microphone connectors loose along those with those of the camera.
Couple of days later a technician shows up, unannounced and unrequested and tells me my intercom unit is defective.
Asked what the problem was he advised me they can't see in the apartment nor hear what's going on.
I told him I had cut the wires (more dramatic) as I don't need the facility. I asked where his company was from he replied: 'Singapore'. He added, most every Singapore apartment has these things and many are connected to the 'emergency' (police/fire) services.
So much for Singapore being a 'free' country.
