Systems and methods for detecting motion based on a video pattern

A system comprising:

• a programmable processor;
• and
• executable control software stored on a non-transitory computer readable medium,
• wherein the programmable processor and the executable control software create a motion image from a sequence of raw images of a region by differentiating the sequence of raw images so that the motion image includes pixels representing only portions of the sequence of raw images where there is a difference between at least one of the sequence of raw images and any subsequent ones of the sequence of raw images,
• wherein the programmable processor and the executable control software mask the motion image with a lens pattern associated with a PIR sensor and an associated Fresnel lens monitoring the region by overlaying the motion image with the lens pattern,
• wherein the programmable processor and the executable control software split each of a plurality of blocks of the lens pattern as overlaid on the motion image into a respective first section and a respective second section,
• wherein the respective first section of each of the plurality of blocks is a respective positive area associated with a first slot of the PIR sensor and the respective second section of each of the plurality of blocks is a respective negative area associated with a second slot of the PIR sensor,
• wherein the programmable processor and the executable control software identify a positive area pixel value as a sum of all of the pixels in the motion image that are aligned with the respective positive area of each of the plurality of blocks,
• wherein the programmable processor and the executable control software identify a negative area pixel value as a sum of all of the pixels in the motion image that are aligned with the respective negative area of each of the plurality of blocks,
• wherein the programmable processor and the executable control software subtract the positive area pixel value and the negative area pixel value as identified from the respective positive area of each of the plurality of blocks and the respective negative area of each of the plurality of blocks of the motion image to identify a motion image response value, and
• wherein the programmable processor and the executable control software identify a presence of motion in the region when the motion image response value exceeds a predetermined value.
