| description | A detection system (10) and a detection method (2000) are disclosed herein. The system includes a PIR sensor (12) positioned in an area comprising a plurality of sub-areas, the motion sensor comprising an optical device (22) having a plurality of sub-lenses (26, 28, 30), each sub-lens of the plurality of sub-lenses having a field of view (FOV) corresponding to a sub-area of the plurality of sub-areas. The system further includes at least one processor (32) coupled to the PIR sensor and configured to: activate the plurality of sub-lenses to generate a total sensor FOV comprising each FOV of the plurality of sub-lenses; and dynamically control the plurality of sub-lenses to subdivide the total sensor FOV, wherein the subdivided sensor FOV is smaller than the total sensor FOV. |
