Understanding the Aqara Doorbell Camera and Its Wiring Requirements

What’s in the Box?

Before you begin, it’s essential to verify what components come with your Aqara Doorbell Camera. The standard wired kit typically includes:

• The Aqara Doorbell Camera unit (main body with camera, speaker, and button)
• Mounting bracket and screws
• Wire connectors and terminal screws
• Transformer compatibility guide (for existing doorbell circuits)
• Quick start guide and safety instructions
• Optional: chime module (if replacing a mechanical chime)

Note: The Aqara Doorbell Camera is designed to work with low-voltage AC power, typically in the 8–24V AC range. This is standard for most traditional doorbell systems, but it’s crucial to confirm compatibility before proceeding.

Power Requirements and Electrical Compatibility

The Aqara Doorbell Camera is not USB-powered or PoE (Power over Ethernet). Instead, it relies on a low-voltage AC transformer connected to your home’s mains power (120V or 230V, depending on your region). Most homes built after the 1980s already have a doorbell transformer, often located in the basement, attic, or near the HVAC system. The transformer steps down the voltage to 16–24V AC, which powers both the doorbell and the internal chime.

Key Tip: Use a multimeter to test the voltage at your existing doorbell terminals. If the reading is below 8V or above 24V, you may need to replace the transformer. Aqara recommends a minimum of 16V AC for optimal performance, especially when using Wi-Fi and video streaming features.

If your home doesn’t have a pre-existing doorbell circuit, you’ll need to install a transformer and run low-voltage wiring from a nearby power source. This is more complex and may require professional assistance, but it’s doable with basic electrical knowledge.

Wired vs. Battery-Powered: Why Choose Wired?

While battery-powered doorbells offer flexibility, the wired Aqara model provides several advantages:

• Continuous power: No need to recharge or replace batteries every few months.
• Stable performance: Avoids power-related dropouts during live viewing or recording.
• Weather resistance: Wired units are better sealed and less prone to moisture damage.
• Smart home integration: Consistent connectivity for automation (e.g., turning on lights when the doorbell is pressed).

For homeowners seeking a “set it and forget it” smart doorbell, the wired version is the superior long-term choice.

Tools, Materials, and Safety Precautions

Essential Tools and Supplies

To wire your Aqara Doorbell Camera safely and correctly, gather the following items:

• Voltage tester or multimeter
• Insulated screwdrivers (flathead and Phillips)
• Wire strippers
• Electrical tape
• Drill and drill bits (for mounting)
• Fish tape (if running new wires through walls)
• Low-voltage wire (18–22 gauge, 2-conductor stranded wire, if replacing or extending wiring)
• Wire connectors (butt splices or Wago connectors)
• Smartphone with Aqara app installed (iOS or Android)
• Optional: Wi-Fi extender or mesh node (if your front door has weak signal)

Pro Tip: Use stranded wire instead of solid-core for easier handling and better conductivity in low-voltage applications.

Critical Safety Measures

Electrical work, even at low voltage, requires caution. Follow these safety rules:

• Turn off power: Shut off the circuit breaker for your doorbell or main panel before touching any wires. Use a non-contact voltage tester to confirm the wires are dead.
• Label wires: Before disconnecting, label the wires (e.g., “Front,” “Rear,” “Common”) to avoid confusion during reinstallation.
• Use insulated tools: Even low voltage can cause a shock if you’re not careful.
• Work in dry conditions: Never install electronics during rain or high humidity.
• Follow local codes: Some areas require permits for electrical modifications. When in doubt, consult a licensed electrician.

Remember: Safety isn’t optional. A few extra minutes to verify power is off can prevent serious injury or damage to your home’s electrical system.

Pre-Installation Checklist

Before you start, complete this quick checklist:

• ✅ Confirmed transformer voltage is between 16–24V AC
• ✅ Tested Wi-Fi signal strength at the doorbell location (aim for at least 2 bars)
• ✅ Downloaded and logged into the Aqara app
• ✅ Verified the doorbell fits the mounting space (check dimensions in the manual)
• ✅ Gathered all tools and materials

Completing this checklist ensures a smooth installation with minimal interruptions.

Step-by-Step Wiring Installation Process

Step 1: Remove the Old Doorbell (If Applicable)

If you’re replacing an existing doorbell, start by removing it:

1. Turn off the circuit breaker for the doorbell.
2. Use a voltage tester to confirm no power is present.
3. Unscrew the mounting plate and gently pull the doorbell away from the wall.
4. Disconnect the wires by loosening the terminal screws. Note which wire connects to “Front” and “Common” (or “Rear” if you have a dual-button setup).
5. Label the wires and tuck them into the wall cavity to prevent them from falling back.

Example: In a typical setup, the “Front” wire connects to the front doorbell, and the “Common” wire returns to the transformer. The “Rear” wire (if present) connects to a back door button.

Step 2: Prepare the Mounting Location

Choose a location that offers:

• Clear view of the entryway (ideally 4–5 feet high)
• Protection from direct rain (under an eave or awning)
• Good Wi-Fi coverage (use a Wi-Fi analyzer app to test signal strength)

Use the mounting bracket as a template to mark drill holes. Drill pilot holes, insert wall anchors, and secure the bracket with screws. Ensure it’s level using a bubble level.

Step 3: Connect the Wires to the Doorbell

Now it’s time to wire the Aqara Doorbell Camera:

1. Feed the existing wires through the center hole of the mounting bracket.
2. Strip about 1/2 inch of insulation from the wire ends.
3. Attach the wires to the terminal screws on the doorbell unit:
   • Connect the “Front” wire to the “Front” terminal.
   • Connect the “Common” wire to the “Common” terminal.
   • Ignore the “Rear” terminal unless you have a back door button.
4. Tighten the screws firmly—loose connections can cause flickering or power loss.
5. Secure the wires with electrical tape to prevent strain on the terminals.

Important: The Aqara Doorbell Camera does not require polarity (positive/negative), so wire order doesn’t matter for AC systems.

Step 4: Mount the Doorbell Unit

Once wired:

1. Align the doorbell with the mounting bracket.
2. Slide it into place until it clicks or is secured with a locking screw (depending on model).
3. Double-check that all wires are tucked neatly and not pinched.

Tip: If the doorbell feels loose, tighten the mounting screws or add a small shim behind the bracket.

Step 5: Power On and Test

Restore power at the circuit breaker. The doorbell should light up within 30 seconds. Test it by:

• Pressing the button—you should hear a chime (if connected to a mechanical chime) or a notification on your phone.
• Checking for a steady LED indicator (solid white means powered; blinking indicates Wi-Fi setup mode).
• Using a multimeter to verify voltage at the terminals (should be 16–24V AC).

If the doorbell doesn’t power on, recheck wiring, transformer voltage, and breaker status.
