After you exchanged the SD cards and later on checked them on your computer you may have forgotten where those pictures were taken.
The Serial No. parameter setting takes care of this issue. You can use the combination of 4 digits and or letters to code the location and record it in the photos (e.g. YSP1 stands for Yellow Stone Park site one). This will help you to identify the location when reviewing the photos off-site.
Tips: Always use NEW high-performance alkaline or lithium batteries. For best performance, we would recommend Energizer Lithium batteries or other
High-quality brands. And if you prefer video mode, always install the factory-provided additional battery box. The video mode needs 8 x AA batteries to function properly.
When the motion indicator flashes blue or the battery icon on the LCD display shows low capacity please change batteries immediately.
Setting a camera up above water also can cause false trigger because the reflection of the heat from the surface will subtly change the surrounding temperature.
Tips: Try not to place the camera close to tree limbs, or remove the limbs, twigs, and leaves from the outreach of the sensors. If in rare situation you cannot avoid the limbs, you can turn off the side Prep Sensors by setting it off in the menu. By doing this you may lose some sensing angles.
Also, try not to aim the camera at the sun or place it in an area with high heat source nearby. Try not to place the camera above water or other reflective objects such as mirrors or glasses.
