Moultrie Trail Cameras use a passive infrared (PIR) sensor to detect when an animal walks in front of it. When the PIR is triggered the camera takes a photo. At times, the PIR will trigger and there won't be anything in the photo. These are called “False Triggers” and are 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 sun beam as hotter than the surrounding environment. Setting a camera up over water is also a potential cause for this issue. Follow these tips to reduce or eliminate false triggers on your Moultrie Trail Camera.
Position your camera facing north. 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 the frame.
Face camera down trail. When covering a trail, position your trail camera at a 45-degree angle to the trail. Doing this will allow your camera the greatest amount of time for an animal to trigger the PIR sensor and capture the subject in the photo. When a trail camera points directly across a trail, then a fast-moving deer or animal will trigger the PIR sensor, but might move out of the camera frame before a photo is captured.
Place camera 15 to 20 feet from subject. This will allow you to get the full animal in the shot. It also ensures that the subject is adequately lit during nighttime images. The farther the animal is from your camera, the less infrared flash will illuminate the subject for clear identification.
Place camera at right height. Strap the camera to a strong tree or camera stand positioned 2 to 3 feet off the ground. If you’re going to strap your scouting camera to a tree, make sure the tree is large enough to not sway in the wind as this can cause a false trigger. Attaching your camera too low and can result in getting too many pictures of squirrels and other small non-targeted creatures.
Clear all vegetation from in front of the camera. Any grasses or small limbs or twigs growing out of the ground in front of the camera can cause a false trigger. Some folks use a weedeater to quickly knock down grass in front of their cameras.
Use proper SD card. Most Moultrie Cameras support up to a 32GB SD card from Class 4 to Class 10. Class 10 cards are recommended for higher performance cameras, particularly when capturing higher-resolution photos and HD video. SD and SD HC cards are recommended while SDXC cards should not be used. Additionally, cards designated as “turbo”, “ultra”, or “super speed”, are not recommended as the speed required by these cards to operate may cause instability in the cameras.
Turn Off Timelapse Mode. Please make sure your unit is not set to the "Timelapse" mode. Timelapse will trigger a photo to be taken at preset intervals without the PIR sensor being triggered. Be sure your camera is set to "Motion Detect" mode to ensure Timelapse isn't engaged.
Remove security sticker inside camera. If your camera has a white security strip inside of the camera door, please remove as this could be pressing down on the menu buttons causing the camera to take false triggers.
If your camera continues to take images when there is no subject in them, try placing the camera in an inside environment and aiming at a location where there is no motion. If the camera continue to show issues, then there may be an electronic component issue. If this is the case, please contact our customer service to send the camera back for repair.
