Hi Bubblers, I am wondering, does any one know how to set up a room view map similar to google map but works for a building with many rooms eg an office with different corners, rooms, or locations and it is possible to view the number of people in each of the corners, locations, rooms in real time? The system I am trying to develop also works like CCTV that that shows different rooms or corners of a building and the traffic in each of the corners/rooms but I don’t want to show people’s images or faces like on CCTV. I just want location “A” 5 persons, Location “B” 2 persons, Location “C” 8 persons etc. represented by objects. Any guidance will be greatly appreciate.
