Before diving into the installation, it’s helpful to understand why having two doorbells makes sense. Many homes have more than one main entrance—think front doors, side gates, or back patios. A single doorbell might miss activity at other access points, especially if it’s placed far away or obstructed by walls or landscaping.
With two Nest Doorbells, you can:
– Monitor multiple entryways in real time
– Receive alerts no matter where someone approaches
– Improve package delivery security
– Deter porch pirates and intruders
– Keep an eye on kids or pets entering/exiting
Plus, Nest Doorbells offer features like HD video, night vision, two-way audio, and intelligent alerts that distinguish between people, packages, and animals. Having two means doubling these benefits across your property.
Choosing the Right Nest Doorbell Models
Google offers two main types of Nest Doorbells:
Nest Doorbell (wired): Requires existing doorbell wiring and a compatible transformer (16–24V AC). It provides continuous power, so you never have to worry about charging.
Nest Doorbell (battery): Runs on rechargeable batteries and can be installed anywhere within Wi-Fi range. Ideal for homes without existing wiring or for secondary locations like side gates.
When installing two doorbells, you can mix and match models. For example:
– Use a wired doorbell at your main front door (where wiring exists)
– Use a battery doorbell at a side or back entrance (no wiring needed)
This flexibility makes Nest Doorbells a great choice for multi-entry homes.
Tools and Materials You’ll Need
Before starting, gather the following tools and materials:
- Nest Doorbell (wired or battery) – 2 units
- Smartphone with Google Home app installed
- Wi-Fi network with strong signal at both locations
- Screwdriver (Phillips head)
- Drill and drill bits (for mounting)
- Level (to ensure straight installation)
- Pencil (for marking drill holes)
- Wire strippers (for wired models)
- Electrical tape (for wired models)
- Voltage tester (optional, for safety)
- Wi-Fi extender (if signal is weak)
- Ladder (if installing high up)
Having everything ready will make the process smoother and faster.
Step 1: Plan Your Doorbell Locations
The first step in installing two Nest Doorbells is deciding where to place them. Good placement ensures clear video, reliable Wi-Fi, and effective motion detection.
Consider These Factors:
Field of View: Choose spots that give a clear view of the approach path. Avoid placing the doorbell too high or too low—eye level (about 4–5 feet from the ground) is ideal.
Wi-Fi Signal Strength: Nest Doorbells need a strong Wi-Fi connection. Use your phone to check signal strength at each location. If it’s weak, consider installing a Wi-Fi extender.
Power Source (for wired models): Wired doorbells must be installed where existing doorbell wiring is present. Check your current doorbell location or consult an electrician.
Weather Protection: Avoid direct exposure to rain or extreme sun. Nest Doorbells are weather-resistant, but overhangs or eaves help prolong their life.
Privacy and Legal Considerations: Make sure your doorbells aren’t pointing into neighbors’ windows or private areas. Follow local laws regarding video surveillance.
Example Placement Ideas:
– Front Door: Centered above the door, 4.5 feet high, wired if possible.
– Side Gate: Near the gate latch, battery-powered, angled to capture the walkway.
– Back Patio: Above the back door, protected by a roof overhang.
Once you’ve chosen your spots, mark them with a pencil and measure the distance between the mounting holes using the included template.
Step 2: Check Electrical Compatibility (For Wired Models)
If you’re installing a wired Nest Doorbell, you must ensure your home’s doorbell system is compatible.
Check Your Transformer Voltage:
Most homes have a doorbell transformer that converts high-voltage household electricity (120V) to low-voltage (16–24V AC). Nest Doorbells require at least 16V to function properly.
To check:
1. Turn off power at the circuit breaker.
2. Remove your existing doorbell button.
3. Use a multimeter to test the voltage across the two wires.
4. If it’s below 16V, you may need to upgrade your transformer.
Tip: If you’re unsure, consult an electrician. Using an incompatible transformer can damage the doorbell or cause it to malfunction.
Prepare the Wiring:
If your voltage is good:
– Strip about 1/4 inch of insulation from the ends of the wires.
– Twist the exposed copper to prevent fraying.
– Label the wires (e.g., “Front” and “Side”) if installing two wired doorbells.
For battery models, skip this step—no wiring is needed.
Step 3: Install the First Nest Doorbell
Now it’s time to mount your first doorbell. We’ll start with the primary location (usually the front door).
For Wired Nest Doorbells:
1. Turn off power: Shut off the circuit breaker for your doorbell to avoid electric shock.
2. Remove old doorbell: Unscrew and disconnect the existing button.
3. Attach the mounting plate: Hold the Nest mounting plate against the wall, align it with the wires, and mark the screw holes.
4. Drill pilot holes: Use a drill to create holes for the screws.
5. Secure the plate: Screw the plate into place using the provided screws.
6. Connect the wires: Attach the two doorbell wires to the terminals on the back of the Nest Doorbell. It doesn’t matter which wire goes where.
7. Snap on the doorbell: Align the doorbell with the plate and press firmly until it clicks into place.
8. Turn power back on: Restore power at the breaker.
For Battery Nest Doorbells:
1. Charge the battery: Plug in the doorbell and charge it fully before installation.
2. Attach the mounting plate: Use the included screws and anchors to secure the plate to the wall.
3. Snap on the doorbell: Align and press until it clicks.
4. No wiring needed: The doorbell runs on battery power.
Level and Adjust:
Use a level to ensure the doorbell is straight. Some mounting plates allow slight angle adjustment—tilt it slightly downward for better motion detection.
Step 4: Install the Second Nest Doorbell
Repeat the same process for the second doorbell at your chosen location (e.g., side gate or back door).
Key Tips for the Second Unit:
– Use a different mounting angle: If the second doorbell is on a different wall, adjust the angle to capture the best view.
– Check Wi-Fi again: Ensure the signal is strong at this location. Weak signals cause lag or disconnections.
– Label the wires (if wired): If both are wired, label the wires at the chime or transformer to avoid confusion later.
For battery models, make sure the second unit is fully charged before mounting.
