Is it the right fit?
Who the Capsule doorbell suits
A good fit when
The capsule chime is 2.3 inches wide, so it sits in the top outlet and leaves the lower one open. It also pairs with our door sensors, which lets one capsule ring for both a doorbell button and a door.
It plays 52 melodies at five volume levels up to 110 dB, with a light that flashes on every ring. The button is IP55 and works down to -4°F. Kits run from one button and one receiver to two of each.
Know before you buy
- The capsule is 4.5 inches tall. Check the space above the outlet.
- Range is 1,000 feet in open air and shorter through walls.
- Each button pairs with up to 20 receivers, but the kit holds two at most.

What buyers say about the Capsule doorbell
5 out of 5
Great unit saves much money if not trying to move existing button and it lets you put chimes in areas that you need to be in, great for hearing impaired.
