Further, in some implementations, an array of IR illuminators 1105 are disposed under the substantially opaque area of the front cover plate 708 and configured to illuminate a field of view of the lens assembly 704 with infrared light in a night mode. In an example, the array of IR illuminators 1105 include a number of e. g. , twelve LEDs arranged in a row. The row of IR illuminators 1105 provide adequate illumination without producing a bright red/visible glow that would result from fewer and more powerful IR illuminators. 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.
