Systems and methods for determining and verifying a presence of an object or an intruder within a secured area are provided. Such systems and methods tan include a microprocessor unit sampling data from a smart microwave sensor module to detect the presence of the object or the intruder, using the data to calculate a velocity of the object or intruder, using the data to calculate a distance between the smart microwave sensor module and the object or the intruder, determining whether the velocity is within a predefined range, and using the distance to determine whether the object or the intruder is within a designated protection territory. Such systems and methods also may include recording trigger positions of the object or the intruder when the velocity is within the predefined range and the distance indicates the object or the intruder is within the designated protection territory.

Some systems and methods for detecting motion based on a video pattern can include creating a motion image from a sequence of raw images, masking the motion image with a lens pattern associated with a PIR sensor and an associated Fresnel lens, splitting each of a plurality of blocks of the lens pattern into first and second negative areas, identifying a positive area pixel value as a sum of all pixels in the motion image aligned with the first positive area in the plurality of blocks, identifying a negative area pixel value as a sum of all pixels in the motion image aligned with the second negative area in the plurality of blocks, identifying a motion image response value as a difference between the positive and negative area pixel values, and identifying a presence of motion when the motion image response value exceeds a predetermined value.
