1. A slot scanner assembly, comprising:
a housing including an optical cavity and an opening;
a window at least partially covering the opening in the housing;
an imaging assembly located within the housing and having a first field-of-view (FOV) directed through the window, the first FOV having a first central axis and the imaging assembly configured to capture an image frame of an environment appearing in the first FOV;
an illumination system configured to provide illumination across at least a portion of the first FOV of the imaging assembly;
a controller in communication with the imaging assembly to control operation of the imaging assembly and the illumination system to control operation of the illumination system;
an image decoder in communication with the imaging assembly and the controller, the image decoder configured to receive the image frame and decode a barcode captured in image data captured by the imaging assembly; and
a wakeup system, the wakeup system comprising:
a first infrared (IR) transmitter positioned within the housing and configured to project IR illumination through the window; and
an IR receiver positioned within the housing, the IR receiver having a second FOV directed through the window, the second FOV overlapping the first FOV of the imaging assembly by at least 50% at the window and having a second central axis that is non-perpendicular to the window such that the second central axis is tilted downward from horizontal with the slot scanner assembly positioned in a vertical first configuration where the window is in a generally upright orientation;
wherein the controller is in communication with the wakeup system and is configured to activate the illumination system when the IR receiver detects IR illumination reflected from an object in the second FOV of the IR receiver.
