I did some work with a group that live trapped elk and they had a camera that when detected motion it would send a text to a predetermined phone number. Then they could then log onto a computer and see what the camera was seeing. They used it to detect if something had triggered the live trap, so they could reset or collar the elk, so they were not in the trap for extended periods of time.
I do not recall the name of the camera, just that it required it's own cell phone plan....
