Gigapixels and Security

Recently I got to see this image which was taken by a camera with a resolution of 1500 mega pixels. I was marvelled and amazed at itz capability to zoom in to such a granular level. I kept zooming in on this Sydney picture and could even see the rooms in that building. It was then I realized that this amazingly awesome camera could pose such a great security risk. what if someone from your next street wants to zoom in and record your every move in your house ? what if someone eyes onto military / business confidential conferences ? the list could go on.. Even though the advancements in technology tries to make us look powerful, it surely seems to add a weak link somewhere !!
