Further, in some implementations, an array of IR illuminators 1105 are disposed under the substantially opaque area of the front cover plate 708 and configured to illuminate a field of view of the lens assembly 704 with infrared light in a night mode. In an example, the array of IR illuminators 1105 include a number of e. g. , twelve LEDs arranged in a row. The row of IR illuminators 1105 provide adequate illumination without producing a bright red/visible glow that would result from fewer and more powerful IR illuminators. In some implementations, the lens assembly 704 is supported by a lens holder 1120 within the device housing 702, and the lens holder 1120 has a top edge raised towards the front cover plate 708 for blocking the infrared light generated by the array of IR illuminators 1105 from entering the lens assembly 704 directly. In some implementations, the IR illuminators 1105 include IR LEDs having a wavelength of 940 nanometers. In some implementations, the IR illuminators 1105 include IR LEDs having a wavelength of 850 nanometers. In some implementations, the image sensor for the doorbell camera 106 is less sensitive to 940 nm light than it is to 850 nm light. Therefore, IR LEDs having a 940 nm wavelength cause less interference with the image sensor than IR LEDs having an 850 nm wavelength. Further, in some implementations, a heat spreader 1128 is coupled to the IR illuminators 1105 to dissipate heat generated therefrom.

The camera a 4K sensor and 12x digital zoom and enhance. A close up tracking feature lets you zoom in on anyone who appears on camera while a picture in picture view gives you a look at the wider shot. The outdoor camera also offers night vision via 850nm infrared LEDs for those hours of the day when the lights are out. The marquee feature of Nest Cam IQ Outdoor is its ability to recognize the difference between people and pets. Nest says the artificial intelligence on the camera can identify people from up to 50 people away. As with the indoor version of Nest Cam IQ, if you want the Familiar Faces feature to identify friends and potential foes, you'll need to buy a $10 per month Nest Aware subscription.

Expect many businesses to be closed or operating under delayed times.

Ask workers to cover this hole up at the end of each day, and arm that area with extra motion sensor alarms and lights.
