We have all been pre-scouting and come across a game trail that looks like a highway.  These are the things that get get us excited – we know the deer are using this corridor and we want to know more!  Most people would be inclined to place a game camera across the trail to see whats happening. Chances are you will end up with plenty of pictures – however those pictures will most likely be of beautiful trees, plants etc – but no deer.  The reason for this is that most trail cameras have a triggertime that can be 1 to 3 seconds or even more.  Trigger time is the time it takes from the camera to recognize heat and/or movement and to “wake up” and snap a picture.   So when a deer is walking down a game trail and the camera is perpendicular to the trail, the deer can be past the camera before it has a chance to snap a picture.  In order to take advantage of that game trail, your best option is to either have the game camera facing up a trail or down a trail.  This way, the camera has a longer time period to wake up and take a picture.
