When watching bird box
webcams viewers often wonder what is going on outside the box. We solved
this problem by added an external outside camera to view birds when the
were at the opening. If a bird was at the opening the inside camera
would switch to the outside camera view for as long as the bird was at
the opening. Then the camera would switch back to the inside view. The
external camera contained a custom designed motion sensor that would
perform the switching between the two cameras.
