- There are privacy issues. If you put your entire neighborhood under video surveillance to spot coyotes, how will people be assured that their privacy isn't being compromised? Who will have access to the video, under what circumstances, and for what period of time? Would someone be able to subponea the videos in a divorce case? In a police investigation?
- It seems that software that would be able to tell the difference between a coyote and a dog from a distance would have to be pretty sophisticated. (Is that a coyote pursuing a runner, or a runner running with her German Shepherd?) I don't know if you'll be able to find that capability without paying lots of money for a customized solution. The cops wouldn't be happy if they got an automated alert every time a dog passed by a camera.
It seems like a low-tech solution might be the best: people keeping an eye out for coyotes and calling the cops if they spot one.
