If used correctly by the dodgy types, these quadcopters with cameras on the front can check out village houses from quite a distance away
1. how to reach the house from the back (any accessible routes)
2. where are the pipes located that can be used to climb up, any pipes without barbed wires
3. which windows are left open or the occupants will think that nobody can get into so they are left open for long periods
4. Does the house have any pets in the garden
5. Any visible security cameras
and so on, its not about what can be seen inside but how to breach the property is the main concern. Once you get into the house, overpowering a maid or an old couple can done easily.

On sai kung group in facebook, a lady did post a picture of a drone that was near her house, I told her to go buy a gas gun and use it as a target practise
