It's very hit or miss. Last night, for instance, the only action was about 5 seconds of an elephant walking past the water hole. The only reason I caught it was because I had the sound on and ran over to the computer when I heard loud crunching. The two previous nights we had Cape Buffalo bathing and then rhino, including a baby, followed by days of more rhino, buffalo, giraffes and elephants. Today seems pretty basic with gnu and impala. I enjoy it best when I have two sessions of Africam open at the same time, both at half screen. One shows me the cam and the other is in the forum where experts tell you what every sound means.
