Ok trail cam experts I have a question on a subject that I haven’t heard about. Are there any trail cams that have an audio trigger to start recording instead of using a motion detector. Possible uses, to detect gun shots in the area you are setup, to hear an elk bugle that doesn’t walk in front of the camera, to hear someone talking who saw your camera and decided not to walk in front of it. If there is such a device would it have an adjustable db value that can be set for the trigger so there isn’t a bunch of false triggers.
