How advanced are spy drones used in the military and law enforcement?

[bluecap]

In this movie Eye in the Sky about drone deployment in the middle east. This is this small electronic beattle which can fly and has built in camera to spy inside houses. Is this technology real? Where can one get it? Should there be none, what is the smallest drone you saw that has good definition camera and can make you fly it inside houses?

This thread is being watched by the FBI and other agencies.

J/K, but I would imagine if I were designing microdrones for LEO agencies, they would be mostly silent and able to land like a fly on the wall for tactical surveillance. Probably we don't need to provide any technical details or tips right now -- anybody can read this thread...
