A number of firms have shown off smart doorbell products at CES, aimed at the growing smart home security market. Amazon-owned Ring's Video Door Cam can be attached via an existing peephole in a door. The firm told the BBC it was aimed at renters who may not be allowed to drill holes in a door. It also has a sensor which notifies you if someone knocks on the door instead of ringing the bell. French firm Netatmo is offering free video storage with its new product.
Today, Netgear announced that it is launching a Arlo-branded doorbell that works seamlessly with its line of security cameras and security lights. The wire-free Arlo Audio Doorbell can replace your traditional doorbell; every time someone rings the doorbell, the Arlo app will call your smartphone, which allows you to speak to your visitors or send a prerecorded greeting. However, you can also use it as a wireless doorbell. It runs on two AA batteries, and Netgear reports that in testing, these lasted for about a year. If you would prefer a more traditional doorbell experience (and don't want the doorbell constantly calling your phone), Netgear will also offer the Arlo Chime.
As various smart home components become more and more generic, manufacturers have started looking for new tricks to distinguish their products from the rest of the crowd. Here's one idea: Take a key feature from another product category and incorporate it into your gear. Meet Exhibit A: The Gate Smart Lock, billed as the first smart lock with an embedded camera. You can think of Gate as a mashup of a retrofit smart door lock and a video doorbell. As a smart lock, it supports three means of gaining entry: physical key, four-digit PIN, or smartphone app.
