CityEngine Security Camera Demo – Video & CGA Code

I saw the CityEngine webinar yesterday on “3D Cities for Safety and Security”   and got inspired by their security camera rule, I thought I could do that quite quickly so came up with this:

Here’s the code for those that like this sort of thing (it’s not carefully commented by feel free to modify and share) I’m aware the CityEngine team have something much more sophisticated but for 5 minutes coding I think it’s quite nice:
