1. An elevator system comprising an elevator entryway, the elevator entryway including:
a door, and the entryway includes an entryway frame surrounding the door, and an entryway landing at the door;
a controller operationally connected to the door for opening and closing the door to provide access to an elevator; and
a plurality of sensors in a unitary package, including a first sensor and a second sensor, the first sensor being a light detection and ranging (LIDAR) sensor and the second sensor being a radio detection and ranging (RADAR) sensor, the plurality of sensors in the unitary package being disposed floor-level, at the entryway landing, near the entryway frame and adjacent to the door,
wherein the plurality of sensors in the unitary package are both configured to monitor the entryway and transmit control instructions, wherein the control instructions are to reopen the door upon sensing motion into and/or out of the entryway, and otherwise the control instructions are to close the door,
wherein the controller is configured to close the door, and during the closing of the door:
the controller monitors for the control instructions from the plurality of sensors in the unitary package over frequencies applicable to LIDAR and RADAR, and
upon receiving the control instructions from the plurality of sensors in the unitary package, and the control instructions conflict with each other, the controller reopens the door.
