Over the last 5 or 10 years my father and I have called hundreds of coyotes, and unless there is something wrong with the animal (rabies, ect) as long as it knows you are a human it will get the he!! out of Dodge...99.9% of the time. Coyotes are curious animals, but they are not dumb. Man is their primary killer, and they know it. Sometimes they do not recognize you in camo, but as soon as they figure it out they will be gone. Don't worry about it.
