TTherefore, 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.
