ChimesAlthough video
doorbells replace the button on your doorbell, some still need the chime already installed in your home. There are two types of doorbell chimes on the market: mechanical and digital. A Ring spokesperson said the main difference is that "Mechanical doorbells make your generic "ding dong" sound, whereas a digital doorbell has a speaker, and can make various sounds, including playing MP3’s and pre recorded sounds.

Likewise, some companies, such as Ring, sell a wireless chime add on that pairs with your doorbell camera.

Most doorbell cameras record subjects in both daytime and nighttime conditions,
usually at an HD video resolution of 720p or greater. Smart Lock PairingOne of the most exciting features of video doorbells is that you can pair most of them with a smart lock such as the Kwikset Kevo and August Smart Lock to let guests in when you're unable to come to the door.
