Smoke Detector
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 doorbell camera 106 may
further include a speaker 1106 contained within a speaker box 1136 that is further disposed in proximity to speaker holes 718. When the speaker holes 718 are located on a bottom rim surface of the device housing 702, the speaker 1106 is placed behind the button assembly 1102 and faces the speaker holes 718. Given that the doorbell camera 106 includes both the microphone 1104 and the speaker 1106, a remote user may review live video streams captured by the camera module of the doorbell camera 106, and have a conversation in real time with the visitor. It is also desirable that the doorbell camera 106 can provide dynamic audio feedback to a user via the microphone 1104 and the speaker 1106. The feedback may concern an operational status of the doorbell camera 106 itself, a status of the outdoor environment surrounding the doorbell camera 106, the operational status of another electronic device associated with the doorbell camera 106, and/or the operational status of a set of electronic devices 106 associated with the doorbell camera. For ease of references, the speaker 1106 and the speaker box 1136 are collectively called the speaker 1106 in this application. For example, you can create rules to have the lights turn on when motion is detected, have your doors unlock when a smoke alarm goes off, and have a camera begin recording when a sensor is triggered.Some systems store recorded video locally on an SD card or a solid state drive, while others offer cloud storage.Locally stored video is a good choice for do it yourselfers on a budget, but you have to be careful not to

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.
