Moultrie Trail Cameras use a passive infrared (PIR) sensor to detect when an object passes in front of it. When the PIR sensor is triggered the camera takes a photo. At times, the PIR sensor will trigger and there won't be anything in the photo. These are called “False Triggers” and could be the result of placing the camera in an environment where tree branches, grass, leaves, etc., are blowing in the wind and creating motion. Sunlight can also cause false triggers as the PIR sensor is reading the sunbeam as hotter than the surrounding environment. Setting a camera up over water is also a potential cause of this issue. Follow these tips to reduce or eliminate false triggers on your Moultrie Trail Camera.
Check how your camera is mounted.
Ensure that if your camera is strapped to a tree, the tree is large enough to not sway in the wind as this can cause a false trigger.
Position your camera facing north or south.
If you position your camera aiming east or west your camera tends to have a greater frequency of false triggers due to the rising or setting sun passing through it's frame.
Place your camera at the right height.
Mount the camera to a strong tree or camera stand positioned 3 to 5 feet off the ground. Attaching your camera too low can result in getting too many pictures of small non-targeted creatures. Placing your camera too high and facing downward can cause the camera to pick up shadows and changes in ground temperature.
Clear all vegetation from in front of the camera.
Any grasses, small limbs or twigs growing out of the ground in front of the camera can cause a false trigger.
Check your camera’s settings.
Double-check that your camera’s PIR sensitivity is set to low and ensure that you aren’t set to multi-shot mode. Refer to your camera's manual for all your settings options.
