Consumer Reports says that the first generation Nest Protect worked well as a CO detector, though it was more effective in sounding an alarm when it spots high CO concentrations than low.

The camera module includes a lens assembly 704 and an image sensor that are configured to capture images, and a wireless transceiver that is configured to exchange data with a remote server over one or more wireless communication networks. The doorbell system is configured to ring a remote chime device in response to a press on a button top 706 of a button assembly. The device housing 702 has a substantially elongated shape. Optionally, the elongated shape has a width that is less than a width of most doorframes available in the market, such that the doorbell camera 106 can be directly mounted on a commonly available doorframe. In some implementations, the lens assembly 704 of the camera module is disposed within a top half of the device housing 702, and the button top 706 of the doorbell system is disposed on a bottom half of the device housing 702. When the doorbell camera 106 is mounted on a wall surface or a doorbell frame, the lens assembly 704 is located on top of the button top 706, thereby allowing a field of view of the lens assembly 704 to remain clear when a user presses the button top 706.
