This is an amazing live web cam from a watering hole in South Africa. I'm not sure if it's triggered by movement or someone is watching the camera remotely and following whatever moves, but it operates 24 hours a day.
I've seen elephants, turtles, wildebeest, deer, wild dogs, and warthogs, in the last couple of days. The action is much better in the daytime. You may find it to be quite addictive.
