In some implementations, the doorbell camera 106 further includes an ambient light sensor ALS assembly 714 at least partially disposed within the lens assembly 704. The ALS assembly 714 is configured to measure amount of light entering the lens assembly 702 from an ambient environment surrounding the lens assembly 704. Part of the ALS assembly 714 is exposed to incoming light, and therefore, visible from a front of the doorbell camera 106 in the lens assembly 704. The ALS assembly 714 is configured to compare the measured amount of light to a threshold illumination level, and the doorbell camera uses corresponding comparison results to determine its operation mode between a daytime mode and a night mode. Specifically, in some situations, the ALS assembly 714 determines that the mount of light entering the lens assembly 702 exceeds the threshold illumination level, and the doorbell camera 106 enables the daytime mode in which the IR illuminators are turned off. Alternatively, in some situations, the ALS assembly 714 determines that the amount of light entering the lens assembly 702 is not greater than the threshold illumination level, and the doorbell camera 106 enables a night mode in which the IR illuminators are optionally turned on to illuminate the field of view of the doorbell camera 106.

The fear of personal loss trumps others’ reasonable expectation of privacy. Although crime rates have been steadily dropping, the illusion that they are on the rise is presented daily by news outlets, focusing on isolated crimes, as well as the makers of security devices. The short term result of this is obviously profits for the companies making such devices. The long term results are a bit more troublesome upon consideration. ‘Mean World Syndrome’ as it is called instigates not only conscious reactions to perceived threats but also subconscious reactions which unfortunately not only influence how people view their neighbors and other community members but also can be passed on to new generations, genetically and environmentally, irrationally giving them someone to hate and direct their fears at. Though born of illusion, these attitudes can lead to real world consequences as people respond to events either through an emotional amplification born of fear, thus over reacting sometimes violently, or by completely disconnecting, unable to act appropriately when another human is violently attacked in their presence.
