personal alarms for seniors
As required by law, the sensors in the Nest Protect smoke alarm have a life expectancy of 10 years, so you won’t have to worry about replacing it for a decade.

Daytime 1080p video from this camera was excellent, but nighttime video was less defined; it was hard to make out people's faces.

I wouldn’t really call the Nest Protect an elegant device since for me, it looked more like a wireless speaker, but there is no doubt that it did take a step into the right direction when it came to the aesthetic value of smoke detectors.

In
some implementations, the camera opening or transparent area 712 has a size substantially larger than that of lenses of the lens assembly 704. By these means, the camera opening or transparent area 712 of the
front cover plate 708 does not become a limiting factor for a margin of a field of view of the doorbell camera 106, and the size of the lens assembly 704 determines the field of view for the doorbell camera 106. Stated another way, the margin of the field of view is limited by physical features of the lens assembly 704, rather than by the camera opening or transparent area 712 of the front cover plate 708. Such a substantially large camera opening or transparent area 712 enables a substantially wide angle view for the doorbell camera 106 when a wide angle lens assembly is applied. In some implementations, the front cover plate 708 includes a substantially opaque area that is distinct from the substantially transparent area of the camera opening 712. An interior surface of the substantially opaque area is painted with dark color ink e. g. , black ink. The dark color ink could be transparent to infrared light, such that the substantially opaque area is opaque to visible light and transparent to infrared light. In an example, the interior surface of the front cover plate 708 is entirely covered by the ink except the button opening 710 exposing the button top 706 and the substantially transparent area 712 covering the lens assembly 704. Further, in some implementations, the doorbell camera 106 includes an array of IR illuminators not shown in FIGS.
