Depending on the combination of chimes and video doorbell hardware you have (or if you want to replace both the front and rear doorbells with video doorbells) you'll likely need a bigger transformer. Doesn't matter if you're installing a Nest doorbell, a Ring doorbell, or even a more DIY-type video doorbell solution like those from Amcrest or similar companies.

There are a few different locations where your transformer might be: near the main electrical panel, inside the doorbell's chime box, the garage, or the attic. You can follow the wiring from your chime to the transformer. A licensed electrician is best prepared to find and replace your transformer and install the doorbell for you. If you don't have a transformer it should be noted that the Ring Doorbell Voltage requirement for the Ring Doorbell 2 is lower because the Ring Doorbell 2 has a built in rechargeable battery, so it can accept a wider range of voltages because it charges the battery that powers the doorbell vs providing direct power to the doorbell. The Rind Doorbell voltage requirement for the Ring Doorbell 2 is between 8V-24V AC. We typically recommend using the Ring Doorbell Pro because it has more features but the Ring Doorbell 2 is a great option if you don’t have access to change out your existing lower power transformer. There are three ways to tell if your transformer has enough power for the Ring Doorbell Pro: 1. Use a multimeter For help hardwiring your wire-free doorbell, visit: How do I hardwire my Arlo Essential Video Doorbell Wire-Free? For many doorbell transformers, you'll likely need a flat-head screwdriver to tighten and loosen the screw terminals. You'll probably find any screws that hold the transformer in place are Phillips-head, so have both types of screwdriver handy when you make the repair.

Use a multimeter to check the voltage level

If the voltage level is between meets the voltage requirement, you can use the doorbell with your current doorbell transformer.

Next, replace it with the Shenzheny Yelingda Door Transformer. The manufacturer includes a set of screws and a threaded clamp. Depending on your desire, you may set it up vertically or horizontally.Why does it matter? When upgrading to a video doorbell, you may find that your doorbell transformer provided enough energy to supply your old-fashioned doorbell button and the chime---but doesn't provide enough energy when you introduce the additional power draw of the video doorbell. Cut the mains power, and replace your previous chime with this one. Connect it to mains using the other end of the cable connectors (brown wire to brown wire and blue wire to blue wire). Here are some common wiring configurations that may apply to your home. One doorbell, one transformer, and one chime connector First thing to find was a wired door chime that works within the same voltage range as the Nest Hello and has enough space in the casing to fit the transformer and the Nest connector.

Try using the Arlo Secure App to install your Arlo doorbell to see if it works with your doorbell transformer. A doorbell transformer is a device that sends the right amount of electricity to power an electric doorbell. Your doorbell transformer can be anywhere in your house, but it’s commonly found in a few places, as listed below. BE CAREFUL TO NOT PULL ON THE WIRES AS YOU MAY DAMAGE THE TRANSFORMER, AND MARK OR WRITE DOWN WHAT WIRE IS CONNECTED TO WHAT BEFORE CUTTING THEM.For more information about installing your Arlo Power Kit, visit: How do I install the Power Kit for my Arlo Essential Video Doorbell Wired? It's a bit of a simplification, but volt-amperes function in much the same way as watts do in AC nomenclature. If you'd like to dive deep into the differences, you can start by reading up on power factors, but you hardly need an amateur electrical engineering degree to follow along here. We’ve listed the best places to look for your doorbell transformer below but also created an entire guide with more specifics on where to look for your doorbell transformer here if you are still having trouble locating your transformer. Top places to look for your existing doorbell transformer: 1. Near Main Electrical Panel 2. Basement 3. Garage 4. Attic 5. Near Furnace or Furnace Room 6. Utility Room 7. Crawl Space How can you tell if your existing transformer has enough power for the Ring Doorbell Pro? To calculate resistance, divide the voltage we need to lower (in this example 8, because 24-16=8) by the current. A multimeter is used to measure current. If, for example, your doorbell system draws 0.5 amps of electricity, the resistance will be 16 Ohms (8V/0.5 amps).
