#1. How Does a Doorbell Get Power

Where does a doorbell get power from? How does my doorbell camera get power?

Video doorbells are powered by 3 types of ways: 16-24 V DC power supply, batteries and solar panel.

AC 16-24 V power supply: Some video doorbells require the existing doorbell wiring to get the power supply.

And the existing doorbell wiring is plugged into your home power outlet.

By connecting your doorbell to the permanent AC power supply, you don’t have to regularly charge your doorbell anymore, and can eliminate the problems associated with the low battery charge.

Battery power: Battery operate doorbells are powered either by the rechargeable or non-rechargeable battery for the power supply.

You don’t need to run a power cable to the doorbell. Simply mount it to the wall on your front door without any wiring.

The drawback is that you’ll need to charge the doorbell before it runs out of power.

Solar power: Solar-powered doorbells come with the rechargeable battery and the solar panel will keep charging the battery for non-stop power supply.

The solar panel charges the doorbell with just a little sunlight and you don’t need to recharge the doorbell anymore.

Mount the solar panel near your doorbell, connect the doorbell to the solar panel and just forget it.

If you are an environmentalist, the solar power is the eco-friendly charging way you are looking for.

Optional charging way — portable power bank: If your home is out of power suddenly, a portable power bank is an emergency charging resource for your doorbell.
