Wondering how to install a doorbell camera? Congrats! You are on the path to making your home safer. Here, we walk you through the steps of replacing your old doorbell with a camera option. The details might change depending on your device’s brand and model. So, be sure to have the manufacturer's instructions handy.

Tips for Buying a Doorbell Camera

First, you will want to know your current doorbell’s voltage, as some camera doorbells may require a specific voltage. Next, consider the resolution and field of view of the device you choose to ensure it meets your surveillance needs. Boosted night vision capabilities for round-the-clock monitoring may also be a key feature to look for. Don’t overlook models with advanced features like two-way audio, motion detection, and cloud storage options (for an extra fee) for added functionality.

  1. Examine the Wiring Configuration

    Identify how the wiring connects to your existing doorbell button and the chime unit. Note the number of wires and their colors. Typically, you'll have two wires: one for power and one for the chime. The power wire is usually connected to a power source, while the chime wire connects to the chime unit.

    Remember to inspect the condition of the existing wiring. Look for signs of wear, damage, or corrosion. If the wiring is in poor condition, you may need to replace it during the installation. If that is the case, consult with a licensed local electrician.

  2. Check the Voltage Rating

    This information is crucial to ensure compatibility with the new unit. Most doorbell cameras operate on low-voltage systems, often around 16 to 30 volts. Ensure that your existing system falls within this range. 

    Employ a voltage tester or meter to check the doorbell transformer's voltage. Configure the meter to read 30VAC (volts alternating current), and then assess the transformer's output. Connect one probe to each screw head, and you should observe a voltage reading.

  3. Identify the Correct Circuit or Fuse

    Find the circuit breaker or fuse box. It's typically located in a basement, utility room, garage, or outside. It contains switches or fuses that control the flow of electricity to various parts of your home, including your doorbell. 

    To cut power to your doorbell, you must identify the specific circuit or fuse that controls it. This might be labeled as a "doorbell" or "chime" on the circuit breaker panel. If there are no labels, you may need to consult your home's electrical plan or use a process of elimination to figure out which one it is.

  4. Turn Off the Circuit Breaker or Fuse

    Now, let’s get to work. Ensure that the power to your current doorbell system is switched off so there are no shocking surprises. Seriously, this is a crucial safety step in the installation process. 

    If you have a circuit breaker panel, locate the switch corresponding to the doorbell. To turn off the power, flip the switch from the "ON" position to the "OFF" position. It's a good practice to double-check that the switch is in the "OFF" position and locked into place to prevent accidental switching back on.

    If you have a fuse box, find the fuse controlling the doorbell circuit. To turn off the power, carefully pull out the corresponding fuse. Keep it safe; you'll need to return it when you're done with the installation. 

  5. Remove the Existing Doorbell

    The exterior button that goes “ding-dong” is usually secured to the wall or door frame with screws. Use a screwdriver to remove these screws and gently pull the button away from the wall. This step will expose the wires connected to the back of the button.

  6. Test for Power

    Even after turning off the circuit breaker or removing the fuse, it's a good practice to grab your voltage tester to confirm electricity is not running through the doorbell wires. Simply touch the voltage tester to the exposed wires; it should not detect any voltage.

  7. Disconnect the Wires

    Disconnecting the wires from your existing doorbell setup is relatively straightforward. Grab your screwdriver and wire strippers to get started. 

    The screwdriver is handy for removing the screws that hold the wires in place. Once the wires are disconnected, you will remove a small amount of insulation using the wire stripper. This step ensures a smooth connection when you install the new device. Why is this important, you might be thinking?

    Underneath the wire’s insulation is the conductor, which carries electrical current. To create a secure connection, you must expose a small portion of the conductor. This exposed conductor is what you connect to terminals, screws, or other electrical components.

  8. Install the Mounting Bracket

    Most doorbell cameras have a mounting bracket or plate. Attach this bracket over the exposed wiring for the doorbell using the screws and anchors included in the kit. You may need to use a drill to accomplish the task. 

    Start by measuring for pilot holes and then drill. After installing the bracket or plate, ensure it is level and securely fastened. 

  9. Thread and Attach the Wiring

    Carefully pull the exposed wires through the mounting bracket or plate opening so you can connect them to the new device.

    Now, you will attach the wiring to your new doorbell camera. You may first need to loosen the screws with the screwdriver on the back of the device for the wiring. Next, using your hands, wrap the wires once or twice around the loose screws. Then tighten the screws.

  10. Install the Camera

    Depending on the model, the doorbell camera may snap onto the mounting bracket or plate, or you may need to secure it with the provided screws. Whatever the case, follow the manufacturer's instructions for your specific camera. Make sure it's level and aligned correctly.

  11. Power It Up

    Flip the switch back on at the circuit breaker or pop that fuse back in to restore power to your doorbell system.

    Now press the doorbell camera button. If it dings, give yourself a pat on the back. If not, you should take a look at the wired connection. If it looks correct but the problem persists, you may want to hire a local security camera installer to help. 

  12. Connect to Wi-Fi

    Download the mobile app or log into the manufacturer's site and follow the instructions to connect your doorbell camera to your Wi-Fi network. This step might involve scanning a QR code or entering a unique code sent by the manufacturer.

    Through your device, tweak the camera's settings to your liking. Adjust things like motion detection sensitivity, notifications, and cloud storage options.

  13. Test

    Here’s the fun part—give your camera's video a spin. Have someone outside your door move around, talk, and ring the doorbell. This is a good time to double-check those motion detection and video settings to ensure everything works smoothly.

DIY or Hire a Pro

Whether to install a doorbell camera yourself or hire a professional depends on your comfort level with electrical work, your technical skills, and the complexity of the installation. Wireless units should be simple to set up on your own, so go ahead and save on the cost of doorbell camera installation.

DIY installation of wired units can be cost-effective too, allowing you to save money on labor costs. If you possess basic electrical knowledge, are comfortable using tools, and can follow instructions, you may be well-equipped to handle the installation.

On the other hand, consider hiring a local professional with security camera experience if you lack the technical skills required for electrical work or if your existing doorbell setup is complex, involving multiple components or non-standard wiring. 

Lastly, hiring a professional ensures the installation is correct and safe. Some manufacturers may also require professional installation to maintain the device's warranty.

Frequently Asked Questions

Chime kits are available for both wired and non-wired doorbell cameras. Usually, these kits are sold separately from the same manufacturer as your current doorbell camera or from a third-party vendor. Ensure you look for chime kits that are designed to work with your specific doorbell camera model to ensure compatibility. Once you get your chime kit, follow the manufacturer's instructions to install it. It may need a wired connection to your doorbell camera or rely on Wi-Fi and an electrical outlet to connect.
