1. An electronic device comprising:
a camera;
a first passive infrared (PIR) sensor including a first PIR element and a second PIR element;
a second PIR sensor including a third PIR element and a fourth PIR element;
a first lens section shaped and dimensioned to direct light onto the first PIR sensor so as to provide:
a first field of view (FoV) for the first PIR element,
a second FoV for the second PIR element, and
a first blind zone between the first FoV and the second FoV;
a second lens section shaped and dimensioned to direct light onto the second PIR sensor so as to provide:
a third FoV for the third PIR element,
a fourth FoV for the fourth PIR element, and
a second blind zone between the third FoV and the fourth FoV; and
a third lens section shaped and dimensioned to direct light onto the second PIR sensor so as to provide:
a fifth FoV for the third PIR element,
a sixth FoV for the fourth PIR element, and
a third blind zone between the fifth FOV and the sixth FoV;
wherein the first lens section, second lens section, and third lens section are arranged such that, when the electronic device is oriented in a first orientation:
the first lens section is disposed vertically above the second lens section and the third lens section,
the third lens section horizontally overlaps the first lens section and the second lens section, and
the first blind zone is azimuthally offset from the second blind zone and the third blind zone.
