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.

Many people overlook placing security cameras in the garage. James Both, an engineer that tests and reviews smart home security cameras for the website onehoursmarthome. com, says that it’s a key place to have one. “Garages are often a target of burglaries because they are easily accessible and oftentimes get accidentally left open,” Both says. “On top of that, garages are full of items that burglars can quickly sell on the black market like bikes, tools, and sporting equipment. ” You might want to put a security camera pointing at your garage door as well as out outwards, too.
