In some implementations, the lens assembly 704 is supported by a lens holder 1120 within the device housing 702, and the lens holder 1120 has a top edge raised towards the front cover plate 708 for blocking the infrared light generated by the array of IR illuminators 1105 from entering the lens assembly 704 directly. In some implementations, the IR illuminators 1105 include IR LEDs having a wavelength of 940 nanometers.
