Batteryless doorbell with rectified power delivery

An audio/video (A/V) recording and communication doorbell device (“A/V doorbell”) circuit comprising:

• a first half-wave bridge rectifier configured to provide power to a signaling device load with a first phase of an AC waveform, the first half-wave bridge rectifier comprising a first diode and a second diode, the AC waveform provided to the first diode and the first phase of the AC waveform output from the second diode, the first phase comprising one of a positive or a negative phase of the AC waveform;
• an A/V doorbell;
• and
• a second half-wave bridge rectifier to provide power to the A/V doorbell with a second phase of the AC waveform, the second half-wave bridge rectifier comprising a third diode and a fourth diode, the AC waveform provided to the third diode and the second phase of the AC waveform output from the fourth diode, the second phase comprising an opposing one of the positive or the negative phase of the AC waveform.

A method comprising:

• determining, by an audio/video (A/V) recording and communication doorbell device (“A/V doorbell”), that a doorbell button has been pressed, the A/V doorbell powered by a first phase of an alternating current (AC) waveform, the first phase of the AC waveform generated by a first half-wave bridge rectifier;
• and
• causing, by the A/V doorbell and in response to determining that the doorbell button has been pressed, an alteration in a second phase of the AC waveform, the second phase of the AC waveform generated by a second half-wave bridge rectifier;
• and
• detecting, by a signaling device controller powered by the second phase of the AC waveform, the alteration in the second phase of the AC waveform;
• and
• energizing, by the signaling device controller and in response to detecting the alteration in the second phase of the AC waveform, a signaling device by causing a signal control switch to close to provide power to the signaling device from the second portion of the AC waveform.
