The Weirdest Broadcasts, Transmissions and Mysterious Noises

I was watching some episode of Bigfoot Hunters, because I'm a big fan of Bigfoot, and during one of their walking around in the woods clips, they suddenly hear a fairly loud BEEEEEEP noise that echoes through the valley they're wandering through. This was basically out in the middle of a wilderness area. They stop, ask, "What was that?" and continue on their way, since it was obviously not a Bigfoot.

But... What WAS that?

Do the batteries on trail cams beep when they're low?

Just wondering.
