Position of the camera

Always place your trail camera looking south or northwards otherwise the rising and setting sun will affect your pictures and some of them will be washed out.
It is necessary to clean any vegetation about 10 meters in front of the camera unless they can activate it when have been moved by the wind.
Place the trail camera above the eye-level of the animals and looking down on the desired area. When the flash is coming from above, it would not scare the game, they assume it similar to lightning. This applies to IR flash and regular one. Mount the camera on height of about 60-100 centimetres, if mounted lowed it will be activated by small animals like squirrels, if mounted higher it can miss those animals.
