Q: Camera takes numerous images with no subject in frame
A: Our cameras have what is known as a “false trigger” when the passive infrared (PIR) sensor detects what it interprets as motion and heat within the detection range of the camera lens when there is no subject in the image. These “False Triggers” are the result of placing the camera in an environment where there is motion associated with tree branches creating motion in front of the camera or an area where there is high heat in the foreground and any motion from wind could set off the camera. Setting a camera up over water is also a potential cause for this issue.

To remedy this situation here are a few tips:

1. Position your scouting camera facing north.
If at all possible, position your camera south of the intended photo area 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.

2. When covering a trail, position your scouting camera at a 45-degree angle to the trail. Doing this will allow your camera the greatest amount of time to trigger and capture the subject.

3. Position your scouting camera approximately 15’-20’ from the intended photo area. To ensure that the subject is adequately lit during nighttime image/photo capture, be sure to place camera within the advertised flash range.

4. Strap the camera to a Stout tree or camera stand positioned 24”–36“ off the ground.
If you’re going to strap your scouting camera to a tree make sure it’s large enough to not sway in the wind. Attaching your camera too low and you're likely to get pictures of squirrels and other small undesirable creatures. If you attach your camera too high you risk false triggers from the tree swaying in the wind.

5. Clear all vegetation from the sensing area of the camera. Avoid false triggers from weeds blowing in the wind.
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.
