Before you touch a single wire, gather these tools and materials. Having everything ready will make the process smoother and safer.
- Kasa Smart Video Doorbell (KE100 or compatible model)
- Screwdriver set (usually Phillips head)
- Voltage tester (non-contact type recommended)
- Wire strippers (if you need to trim or re-strip wires)
- Drill and drill bits (if mounting on brick, stucco, or concrete)
- Wall anchors (if needed for your wall type)
- Smartphone or tablet with the Kasa app installed
- Wi-Fi network (2.4 GHz band required; 5 GHz not supported)
- Ladder (if your doorbell is high up)
- Gloves and safety glasses (optional but recommended)
Pro tip: If you’re unsure about your doorbell’s wiring or voltage, take a photo of the existing setup before disconnecting anything. This can help if you need to reference it later.
Step 1: Turn Off the Power
Safety first! Working with electrical wires can be dangerous if the power is still on. Even though doorbell circuits are low voltage, they can still give you a shock or damage your new device.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “doorbell,” “chime,” or “front door.” If there’s no label, you may need to test breakers one by one.
Turn Off the Correct Breaker
Switch off the breaker that controls your doorbell. To confirm it’s off, go to your doorbell and press the button. If the chime doesn’t sound, the power is off. For extra safety, use a non-contact voltage tester near the wires to ensure no current is flowing.
Important: Never assume the power is off just because the chime is silent. Always test with a voltage tester.
Leave a Note
Tape a note to the breaker box saying “Doorbell work in progress – do not turn on.” This prevents someone else from accidentally restoring power while you’re working.
Step 2: Remove the Old Doorbell
Now that the power is off, it’s time to take down your existing doorbell.
Unscrew the Faceplate
Use your screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the faceplate away from the wall. You should see two wires connected to terminals (usually labeled “Front” and “Trans” or just two screws).
Disconnect the Wires
Loosen the screws and carefully remove the wires. Don’t let them fall back into the wall. You can tape them to the wall or hold them with a clip to keep them accessible.
Inspect the Wiring
Check the condition of the wires. If they’re frayed, corroded, or too short, you may need to strip fresh ends or extend them. Use wire strippers to expose about 1/4 inch of copper if needed.
Remove the Old Mounting Plate (if applicable)
Some doorbells come with a mounting bracket. Unscrew and remove it. You’ll be replacing it with the Kasa mounting plate.
Step 3: Check Doorbell Compatibility
Not all doorbells are compatible with smart video doorbells like Kasa. Before proceeding, verify that your home’s electrical system can support the KE100.
Check Transformer Voltage
Your doorbell transformer should output between 16 and 24 volts AC. Most older homes have 16V transformers, which work fine. You can check this by:
- Looking at the transformer (usually near the chime unit or in the basement)
- Reading the label for voltage and amperage (e.g., 16V, 10VA)
- Using a multimeter to test the voltage at the doorbell wires (with power on)
If your transformer is below 16V or above 24V, you may need to replace it. Kasa recommends a 16V, 30VA transformer for optimal performance.
Check Chime Compatibility
The Kasa doorbell works with most mechanical and digital chimes. However, some advanced digital chimes (like those with multiple tones or LED displays) may not be compatible. If your chime is very modern or branded (e.g., Ring Chime Pro), check Kasa’s compatibility list online.
If your chime isn’t compatible, you can:
- Use the Kasa doorbell without a chime (relying on app notifications)
- Install a Kasa Smart Chime (sold separately)
- Replace your existing chime with a compatible mechanical one
Wi-Fi Signal Strength
Your doorbell needs a strong 2.4 GHz Wi-Fi signal. Use your phone to check the signal strength at the installation spot. If it’s weak, consider:
- Moving your router closer
- Using a Wi-Fi extender
- Installing a mesh network system
Kasa doorbells don’t support 5 GHz networks, so make sure your 2.4 GHz band is active and not hidden.
Step 4: Install the Kasa Mounting Plate
The Kasa doorbell comes with a mounting plate that attaches to your wall. This plate holds the doorbell securely and hides the wires.
Position the Mounting Plate
Hold the mounting plate against the wall where you want to install the doorbell. Make sure it’s level and at a comfortable height (usually 48 inches from the ground). Use a level tool to check.
Mark the Screw Holes
Use a pencil to mark the spots where the screws will go. If you’re mounting on wood or drywall, you can screw directly in. For brick, stucco, or concrete, you’ll need to drill pilot holes and use wall anchors.
Drill Pilot Holes (if needed)
If using anchors, drill holes slightly smaller than the anchor size. Tap the anchors into place with a hammer.
Secure the Mounting Plate
Line up the plate with the marks and screw it into place. Make sure it’s tight and doesn’t wobble. The wires should feed through the center hole.
Step 5: Connect the Wires to the Kasa Doorbell
Now it’s time to connect your home’s doorbell wires to the Kasa device.
Identify the Wires
You should have two wires: one from the doorbell button (usually labeled “Front”) and one from the transformer (labeled “Trans”). It doesn’t matter which wire goes where—Kasa doorbells are non-polarized.
Strip the Wire Ends (if needed)
If the wire ends aren’t exposed, use wire strippers to remove about 1/4 inch of insulation.
Attach Wires to the Doorbell
The Kasa doorbell has two terminal screws on the back. Loosen them, insert the wires, and tighten the screws. Make sure the copper is fully under the screw and not touching each other.
Tip: If the wires are too short, you can use wire nuts to extend them with spare 18-gauge wire.
Secure the Doorbell to the Mounting Plate
Align the doorbell with the mounting plate and press it into place. It should click securely. Use the provided security screw to lock it in place and prevent theft.
Step 6: Restore Power and Test the Doorbell
With everything connected, it’s time to turn the power back on and test.
Turn the Breaker Back On
Go to your electrical panel and flip the doorbell breaker back on. Wait a few seconds for the system to power up.
Check the Doorbell Light
The Kasa doorbell has a status light on the front. When powered, it should glow solid green or blue, indicating it’s receiving power and connecting to Wi-Fi.
If the light is red or blinking, there may be a wiring or power issue. Double-check connections and voltage.
Test the Chime
Press the doorbell button. If you have a compatible chime, it should ring. If not, you’ll rely on app notifications.
Step 7: Set Up the Kasa Doorbell Using the App
The Kasa app is your control center for the doorbell. Download it from the App Store (iOS) or Google Play (Android) if you haven’t already.
Create or Log In to Your Kasa Account
Open the app and sign in. If you’re new, create an account using your email.
Add a New Device
Tap the “+” icon and select “Doorbell” from the list. Follow the on-screen prompts.
Scan the QR Code
The app will ask you to scan the QR code on the back of the doorbell or the packaging. This links the device to your account.
Connect to Wi-Fi
Select your 2.4 GHz Wi-Fi network and enter the password. The doorbell will connect within a minute. Make sure your phone is on the same network.
Name Your Doorbell
Give it a name like “Front Door” or “Main Entrance” so you can identify it easily.
Complete Setup
The app will guide you through final steps, including:
- Setting motion sensitivity
- Enabling two-way audio
- Choosing notification preferences
- Testing the live view
Step 8: Customize Your Kasa Doorbell Settings
Now that it’s installed, make the most of your smart doorbell.
Set Up Motion Zones
In the app, go to “Motion Detection” and draw zones where you want alerts (e.g., walkway, driveway). Avoid areas like busy streets to reduce false alarms.
Adjust Video Quality
Choose between HD and standard resolution. Higher quality uses more bandwidth but gives clearer footage.
Enable Night Vision
The Kasa doorbell has infrared night vision. Make sure it’s turned on in the settings for clear nighttime viewing.
Set Up Two-Way Talk
Test the microphone and speaker. You can talk to visitors directly from the app.
Schedule Do Not Disturb
Set quiet hours when you don’t want motion alerts (e.g., during sleep).
Link to Other Smart Devices
Integrate with Kasa smart lights, plugs, or Alexa/Google Assistant for voice control and automation.
