Hi John :

here is link to a Youtube video on

Chicago's Big Brother Camera System

All the doves should take a look
 

It will shock you how advanced the cameras and command centers are

They even have gun shoot detection and each officer can view any camera from his

car.

It is the most advanced system in the nation.

  

Thanks for all you hard work
