Abstract
Doorbells often include a button to enable visitors to ring a chime to summon building occupants. In some embodiments, doorbells include a camera to take pictures of visitors. In several embodiments, doorbells include covers that are light filters. These light filters can cover infrared light sources such as infrared light emitting diodes. The light filters can pass infrared light while blocking visible light. In several embodiments, a front portion of a camera assembly fits through a hole in a light filter. Light filters can help secure camera assemblies and can form a portion of a doorbell's outer housing.
