Referring to FIG. 10C, in some implementations, the doorbell camera 106 includes a voltage monitoring unit 1022 configured to generate the supply monitoring signal based on the input AC voltage. The LED indicator of the doorbell camera 106 is configured to, based on a value of the supply monitoring signal, display on a surface of the device housing 702 one of a set of predetermined visual patterns, thereby sending a visual message to a user of the doorbell camera 106 to indicate whether the input AC voltage is low with respect to the supply threshold. For example, the supply threshold may be 8V. 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.

TAt CCTV Camera World we believe in quality and reliable surveillance products. Our indoor security cameras are perfect for use in any business, professional, or home setting where there is need for a CCTV camera. Unlike cheap cameras offered by our competitors, all of our indoor cameras have Day and Night technology that allows the camera to switch to black and white mode in low light so the camera can still see. Except for hidden cameras, almost all of our indoor cameras have infrared night vision to see in complete darkness. Below you can find cameras based on use, signal type, or resolution. As the CCTV industry matures, higher resolution megapixel security cameras are becoming more affordable.
