These locks can detect your presence automatically using Bluetooth in your smartphone or keyfob and unlock the door for you. The best digital door locks will also connect to your home automation system and inform other devices such as the smart thermostat that you are away and to enter into energy saving mode. While Bluetooth locks are more secure, they have fewer features. Wi Fi locks on the other hand have more functionality, such as the ability to see if the door is locked in real time. However, the connection to the Internet also makes Wi Fi locks more vulnerable to online security breaches. 3.

TWhen 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.
