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.

TFor these reasons and more I have been researching and comparing "smart doorbell" products since the first models hit the market a few years back. Our household has been through a SkyBell original, SkyBell 2. 0, Ring, and now the SkyBell HD I plan to stick with this one. The first two 2 iterations of the SkyBell product were just so so. They had lots of potential but did not quite deliver. SkyBell HD on the other hand is a dramatic improvement and is still getting better.
