What You’ll Need Before Starting

Before you begin, make sure you have all the necessary tools and materials. Rushing into the installation without preparation can lead to mistakes or safety hazards.

Tools and Materials Checklist

• Eken a V5 WiFi doorbell kit (includes doorbell unit, mounting plate, screws, anchors)
• Screwdriver (Phillips head)
• Voltage tester (non-contact type recommended)
• Wire strippers (if wires need trimming)
• Electrical tape
• Optional: Drill and drill bits (for mounting on brick or concrete)
• Optional: Level (to ensure the doorbell is straight)
• Optional: Smartphone or tablet with the Eken app installed

It’s also helpful to have a helper nearby, especially if you’re working on a ladder or need someone to test the chime inside while you’re outside.

Check Your Existing Doorbell System

Not all homes are ready for a hardwired smart doorbell. The Eken a V5 requires a transformer that outputs between 16 and 24 volts AC (alternating current) and at least 20VA (volt-amperes). Most older homes have transformers in this range, but it’s essential to verify.

To check:

1. Locate your existing doorbell transformer. It’s usually found in the basement, garage, attic, or near your electrical panel.
2. Look for a label that shows the voltage and VA rating. For example: “16V AC, 30VA” is ideal.
3. If you can’t find the transformer or it’s labeled below 16V or under 20VA, you may need to upgrade it.

You can also test the voltage at the doorbell wires using a multimeter. Turn off the power, remove the old doorbell, and touch the probes to the two wires. If the reading is between 16 and 24 volts AC, you’re good to go.

Step 1: Turn Off the Power

Safety should always come first when working with electricity. Even though doorbell circuits are low voltage, they can still cause shocks or damage your equipment if mishandled.

Locate and Shut Off the Correct Breaker

Doorbell transformers are typically connected to a dedicated circuit or tied into a lighting circuit. Here’s how to find and turn it off:

1. Go to your main electrical panel (breaker box).
2. Look for a breaker labeled “Doorbell,” “Chime,” or “Front Door.” If there isn’t one, you may need to test circuits.
3. Turn off the suspected breaker and go to your existing doorbell. Press the button—if the chime doesn’t sound, you’ve found the right one.
4. If the chime still works, turn the breaker back on and try another until you find the correct one.
5. Once identified, turn off the breaker and place a note on the panel so no one accidentally turns it back on.

Double-Check with a Voltage Tester

Even after turning off the breaker, it’s smart to confirm there’s no power at the doorbell wires.

1. Remove the old doorbell from the wall.
2. Use a non-contact voltage tester near the exposed wires. If it beeps or lights up, the power is still on—double-check your breaker.
3. If the tester stays silent, you’re safe to proceed.

Never skip this step. A simple mistake could damage your new doorbell or cause injury.

Step 2: Remove the Old Doorbell (If Applicable)

If you’re replacing an existing doorbell, you’ll need to remove it before installing the Eken a V5.

Unscrew and Disconnect

1. Use a screwdriver to remove the screws holding the old doorbell to the wall.
2. Gently pull the doorbell away to expose the two wires connected to the back.
3. Note which wire goes to which terminal (usually labeled “Front” and “Trans” or just two screws).
4. Loosen the screws and carefully disconnect the wires. Don’t let them fall back into the wall.

Prepare the Wires

The exposed ends of the wires should be about 1/4 inch long. If they’re too short, frayed, or damaged:

1. Use wire strippers to trim the ends and expose fresh copper.
2. Twist the strands gently to keep them neat.
3. If the wires are too short to reach the new mounting plate, you may need to extend them with wire nuts and additional low-voltage wire.

Keep the wires separated and away from each other to prevent short circuits.

Step 3: Install the Mounting Plate

The Eken a V5 comes with a sturdy mounting plate that secures the doorbell to the wall. Proper installation ensures a stable connection and prevents wobbling.

Position the Plate

1. Hold the mounting plate against the wall where you want to install the doorbell.
2. Use a level to make sure it’s straight. Crooked doorbells look unprofessional and may affect motion detection.
3. Mark the screw holes with a pencil.

Drill and Secure

If you’re mounting on drywall:

1. Use the provided screws and plastic anchors.
2. Drill pilot holes slightly smaller than the anchors.
3. Tap the anchors into the wall, then screw the plate in place.

If you’re mounting on brick, stucco, or concrete:

1. Use a masonry drill bit to create holes.
2. Insert wall anchors designed for masonry.
3. Secure the plate with appropriate screws.

Make sure the plate is tight and doesn’t wiggle. A loose mount can cause poor contact with the wires.

Route the Wires Through the Plate

1. Feed the two doorbell wires through the center hole in the mounting plate.
2. Leave enough slack (about 3–4 inches) to connect to the terminals.
3. Trim excess wire if needed, but don’t cut too short.

Step 4: Connect the Wires to the Eken a V5

Now it’s time to connect the wires to the doorbell. The Eken a V5 has two terminal screws on the back of the mounting plate.

Identify the Terminals

The two terminals are usually unlabeled, but they’re symmetrical—meaning polarity doesn’t matter. You can connect either wire to either terminal.

Attach the Wires

1. Loosen both terminal screws on the mounting plate.
2. Insert one wire into each terminal slot.
3. Tighten the screws securely. The copper should be fully wrapped and not exposed.
4. Gently tug on the wires to ensure they’re held firmly.

Use Electrical Tape for Extra Security (Optional)

For added protection, wrap electrical tape around the base of the terminals to prevent accidental contact or loosening over time.

Install a Diode (If Needed)

If your home has a mechanical chime (the kind with physical hammers that strike bells), you may need to install a diode across the chime terminals. This prevents voltage spikes when the button is pressed, which can damage smart doorbells.

1. Open the chime unit inside your home.
2. Locate the two terminals connected to the doorbell wires.
3. Connect a diode (1N4007 or similar) across the terminals, observing polarity (the stripe goes to the positive side).
4. Secure with electrical tape or wire nuts.

Most modern electronic chimes don’t require a diode, but it’s a good precaution if you’re unsure.

Step 5: Attach the Doorbell Unit

With the mounting plate secure and wires connected, it’s time to attach the Eken a V5 doorbell.

Align and Snap Into Place

1. Hold the doorbell unit with the camera facing outward.
2. Align the slots on the back of the unit with the hooks on the mounting plate.
3. Gently press the doorbell onto the plate until it clicks into place.
4. Give it a slight tug to ensure it’s locked securely.

Check the Angle

The Eken a V5 has a wide-angle lens, but you’ll want to angle it slightly downward to capture visitors at the door. Most mounting plates allow for minor adjustments. If needed, use the included angle adjustment tool or shims to tilt the plate.

Step 6: Restore Power and Test

Now that everything is installed, it’s time to turn the power back on and test the system.

Turn the Breaker Back On

1. Return to the electrical panel.
2. Turn the doorbell breaker back on.
3. Wait 30–60 seconds for the system to power up.

Test the Doorbell

1. Press the doorbell button. You should hear the chime inside your home.
2. If the chime doesn’t sound, check the wiring connections and ensure the transformer is adequate.
3. Open the Eken app on your smartphone and check if the doorbell appears online.
4. Verify that live video, motion detection, and notifications are working.

If the doorbell powers on but doesn’t connect to WiFi, make sure you’re within range of your router and that the signal isn’t blocked by thick walls or metal surfaces.

Troubleshooting Common Issues

Even with careful installation, you might run into problems. Here’s how to fix the most common ones.

Doorbell Won’t Power On

• Check the breaker: Ensure it’s turned on and not tripped.
• Test the voltage: Use a multimeter to confirm 16–24V AC at the wires.
• Inspect connections: Loose or reversed wires can prevent power flow.
• Upgrade the transformer: If voltage is too low, replace the transformer with a 16V or 24V, 30VA model.

Chime Doesn’t Ring

• Check chime wiring: Ensure the wires are connected to the correct terminals inside the chime unit.
• Install a diode: Mechanical chimes may need a diode to work with smart doorbells.
• Bypass the chime: If you only want app notifications, you can disconnect the chime and use a plug-in chime or smart speaker instead.

Poor WiFi Connection

• Move the router closer: Or use a WiFi extender to boost signal at the front door.
• Change the channel: Use your router’s admin panel to switch to a less congested WiFi channel.
• Reposition the doorbell: Avoid mounting near metal doors, gutters, or large appliances that block signals.

Doorbell Overheats or Shuts Off

• Check voltage: Too high a voltage (above 24V) can overheat the device.
• Ensure ventilation: Don’t cover the doorbell or mount it in direct sunlight for long periods.
• Update firmware: Use the Eken app to check for and install any available updates.

Maintenance Tips for Long-Term Performance

Once your Eken a V5 is up and running, a little maintenance goes a long way.

Clean the Lens Regularly

Dust, dirt, and fingerprints can blur the camera. Use a soft, lint-free cloth to wipe the lens every few weeks.

Check Connections Annually

Over time, wires can loosen due to temperature changes or vibration. Once a year, turn off the power and inspect the terminal connections.

Update the App and Firmware

The Eken app occasionally releases updates that improve performance, add features, or fix bugs. Enable automatic updates if available.

Monitor Battery Health (If Using Backup)

Even when hardwired, the Eken a V5 uses a small backup battery. If the power goes out, the doorbell may switch to battery mode. Check the battery status in the app and replace it every 1–2 years.
