You can learn how stealth cameras work in the tiger exhibit at the Bronx Zoo. In at least one case, the picture recorded by the stealth cam sealed the conviction

picture proved that they did break the law. Thanks to the laws and enforcement
that EIA works for, one was sentenced to four years and another to five, the
longest such sentence yet for this sort of crime. Read more about the efforts to save big cats with big data in
