Check the Motion Detection settings both during the day and night. In low-light
conditions (or when your cameras are using infrared night vision) the Camera may be
more or less sensitive to motion, depending on the circumstances. The difference
might be very dramatic!

Weather
The weather conditions are going to affect your motion detection. Dramatic weather
phenomenon such as heavy rain, strong winds, lightning and so on, may trigger the
motion detection with surprising frequency. On the other hand, things like fog, mist and
other obscuring kinds of weather might mask or obscure something moving to the
point that the camera fails to detect them.
Here are a few steps you can take to minimize the amount of noise in your images.
1. Try adjusting the Image Settings to fine-tune the brightness and contrast to get a
more stable image.
2. Limit the motion sensitive area to only the areas in view that a target could be. In
particular, large featureless areas in the camera's view are the ones most likely to
give false triggers - turning off the motion sensitivity to any area a target cannot
move in front of will help reduce false triggers.
