The IR filter 1134 is activated in the daytime mode for precise color reproduction, and disabled in the night mode for greater light sensitivity when the field of view of the doorbell camera 106 is illuminated by the IR illuminators 1105. Optionally, the ALS
assembly 714 is also used to cause switching between the daytime and night modes, and enable/disable the IR illuminators 1105 and the infrared filter 1134. In some implementations, the lens holder 1120 is supported by the infrared filter 1134 to protect lenses in the lens assembly 704 from being pushed when a user touches or presses the front cover plate 708. The doorbell camera 106 may include at least a sensor board
1108, a main board 1110 and a secondary board 1112 that are stacked within the device housing 702. In some implementations, the sensor board 1108 includes a connector 1108A that is coupled to another connector of the main board 1110 directly. Alternatively, a flexible cable is optionally connected to the connector 1108A for electrically coupling the main board 1110 to the sensor board 1108. In some implementations, two ends of a flexible printed circuit FPC 1126 are electrically coupled to a respective connector at the main board 1110 and the secondary board to couple them to each other. The sensor board 1108 optionally sits on a rear interior surface of the device housing 702. An image sensor array 1114 may be disposed on top of an end of the sensor board 1108, and the lens assembly 704 may be further disposed on top of the image sensor array 1114, such that light passing through the lens assembly 704 arrives at the image sensor array 1114 to form an image captured by the image sensor array 1114. In some implementations, the sensor board 1108 includes an image processor. The image processor of the sensor board 1108 is optionally located directly below the image sensor array 1114 to facilitate further processing of the image captured by the image sensor array 1114.

security systems for houses
After you connect this Wi Fi smoke alarm to the internet, you can control, monitor and test the device remotely though a useful mobile app. The app also tracks battery life and
allows the unit to test itself on a monthly basis. At night, the
Nest Protect can detect movement and light levels nearby, allowing it to turn on a nightlight when you get up to visit the bathroom. 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. Unfortunately, the device warranty is only two years, unlike the 10 year warranties of the First Alert Onelink and Kidde KN COSM B RF. The Nest Protect smoke alarm is part of the company’s wider smart home strategy, which also includes thermostats, security cameras, security systems and video doorbells.
