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. In some implementations, the IR illuminators 1105 include IR LEDs having a wavelength of 940 nanometers. In some implementations, the IR illuminators 1105 include IR LEDs having a wavelength of 850 nanometers. In some implementations, the image sensor for the doorbell camera 106 is less sensitive to 940 nm light than it is to 850 nm light. Therefore, IR LEDs having a 940 nm wavelength cause less interference with the image sensor than IR LEDs having an 850 nm wavelength. Further, in some implementations, a heat spreader 1128 is coupled to the IR illuminators 1105 to dissipate heat generated therefrom. The doorbell camera 106 may further include a speaker 1106 contained within a speaker box 1136 that is further disposed in proximity to speaker holes 718. When the speaker holes 718 are located on a bottom rim surface of the device housing 702, the speaker 1106 is placed behind the button assembly 1102 and faces the speaker holes 718.
