How to Connect an AC Power Supply to Your Swann Security Doorbell

Setting up your Swann Security Video Doorbell for continuous, reliable operation involves connecting it to an AC power source. While the idea of working with electrical connections might seem daunting at first, the process is straightforward and hassle-free. One of the key benefits of using AC (Alternating Current) power is that it doesn't have polarity concerns like DC (Direct Current) systems. This means you don't have to worry about which wire goes where, simplifying the installation process significantly.

In this guide, we will walk you through the steps to connect your video doorbell to an AC power supply. We will provide detailed instructions, and offer some tips to ensure a smooth and safe setup. Whether you're a seasoned DIY enthusiast or a complete beginner, this article will help you get your video doorbell up and running in no time.

WARNING: Before you proceed, it’s crucial to watch the instructional video provided below. This will give you a visual understanding of the steps involved and help you determine if you feel confident enough to complete the installation yourself.
Unsure about the installation with AC power? We recommend to seek help from a professional electrician to ensure your safety and the proper installation of your device.

Installation

1. Use a voltmeter to ensure that the standard powerline has 12 to 24VAC
2. Loosen both terminals on the rear of the unit
3. Secure the included wire connectors to the terminals
4. Remove the pre-cut insulation from the wire

5. Secure the wires to your existing 12 to 24VAC (up to 0.5A) power using the included wire nuts

6. Align the slot of the rear of the doorbell with the bracket and then slide it down into place
7. Tighten the anti-tamper screw with a small Philip screwdriver

Understanding AC Power Connections: No Need to Worry About Polarity

When you connect your video doorbell to an AC power source, you don't have to worry about which wire goes where. This is different from DC power connections, where polarity (positive and negative terminals) matters a lot.

Example:

Think of it like plugging in a lamp to a wall socket. You don't need to check which prong goes into which hole in the outlet; you just plug it in, and it works. This is because AC power alternates direction, so the concept of positive and negative doesn't apply. Unlike DC, where a battery has a clear positive (+) and negative (-) side, AC power cycles back and forth, making both wires interchangeable for the connection.

While the doorbell is on AC connection, it would show in its settings that it is Charging (see Image 1) until it reaches 100% or Full Charge (see Image 2).
