As I understand it, good calibration prevents most false readings.
However, during the testing process, we didn't try to channel birds or
dogs through the counting area to verify this. I don't think either
would introduce significant biases to counts at any of the sites we
looked at, though a counter sited in a park might have a problem.

No: the IR providers/developers we talked to (Napier, Irisys,
Footfall) only offered direct overhead mounting.
