When the input AC voltage is greater than 8V, the supply monitoring signal may control the LED indicator to display a green color along the peripheral
edge 1040 of the doorbell button 1002, indicating that the input AC voltage is sufficient to drive the doorbell camera 106. In contrast, when the input AC voltage is not greater than 8V, the supply monitoring signal may control the LED indicator to display a red color along the peripheral edge 1040 of the doorbell button 1002, indicating that the input AC voltage is insufficient to drive the doorbell camera 106. Referring to FIG. 10D, in some implementations, the bypass
unit 1012 may also function as a voltage meter to determine whether the transformer 1010 can provide a supply voltage sufficient to drive the doorbell camera 106 which normally consumes more power than a conventional doorbell. The bypass unit 1012 includes a voltage monitoring unit 1012A, an LED indicator 1012B, and bypass circuit 1012C. The supply monitoring signal is generated by the voltage monitoring unit 1012A of the bypass unit 1012, and the LED indicator 1012B is located in the bypass unit 1012.

It features extended battery life, offering two years of battery life with just two AA lithium batteries. When used exclusively for motion activated recording or Live View, Blink XT2 provides double the usage of the original Blink XT on a single set of batteries. Or customers can use two way talk and still get the same two year battery life. It also comes with enhanced motion
detection, including micro activity zones to more precisely customize motion detection and reduce false motion alerts, so you are alerted only of the movement that matters. Plus, Blink XT2 is wire free, making it easy to install indoors or out for complete coverage and peace of mind. “We listened to our customers and delivered a product that not only
improves existing standout features such as two year battery life, but also adds new features like two way talk and enhanced motion detection to further improve the product experience,” said Peter Besen, GM of Blink.
