What You’ll Need Before Starting

Before you begin, gather all the tools and materials. Having everything ready saves time and reduces frustration.

Tools Required

• Voltage tester (non-contact)
• Screwdriver (Phillips and flathead)
• Wire stripper
• Drill and drill bits (if mounting to brick or concrete)
• Ladder (stable and tall enough for your mounting height)
• Electrical tape
• Wire nuts (usually included with the floodlight)

Materials and Accessories

• Eufy floodlight camera (e.g., eufy Floodlight Cam E340 or E330)
• Mounting bracket (included)
• Screws and wall anchors (included or purchased separately for masonry)
• Silicone sealant (optional, for extra weatherproofing)
• Smartphone with eufy Security app installed

Safety Gear

• Rubber-soled shoes
• Safety glasses
• Work gloves

Pro Tip: Charge your phone and ensure your Wi-Fi is working before starting. You’ll need it for the app setup later.

Step 1: Turn Off the Power

Safety comes first. Working with electricity is dangerous if you don’t take precautions. Always turn off the power at the source.

Locate Your Circuit Breaker

Find your home’s main electrical panel. It’s usually in the garage, basement, or utility closet. Look for the breaker labeled “outdoor lights,” “exterior,” or something similar. If it’s not labeled, you may need to test breakers one by one.

Switch Off the Correct Breaker

Turn the breaker to the “OFF” position. Use a non-contact voltage tester to confirm the power is off. Touch the tester to the wires inside the existing light fixture. If it beeps or lights up, the power is still on—double-check the breaker.

Lock Out the Breaker (Optional but Recommended)

If someone else might access the panel, use a breaker lock or tape a note to prevent accidental reactivation.

Important: Never assume the power is off. Always test with a voltage tester before touching any wires.

Step 2: Remove the Old Light Fixture (If Applicable)

If you’re replacing an existing outdoor light, you’ll need to remove it first. This step ensures a clean, secure mount for your new eufy floodlight.

Unscrew the Mounting Bracket

Use a screwdriver to remove the screws holding the old fixture to the wall or junction box. Support the light with one hand while unscrewing to prevent it from falling.

Disconnect the Wires

Carefully pull the fixture away from the wall. You’ll see three wires: black (hot), white (neutral), and green or bare copper (ground). Unscrew the wire nuts and separate the wires.

Remove the Old Junction Box (If Necessary)

If the existing box is damaged or too small, replace it with a standard outdoor electrical box. Secure it firmly to the wall using screws and anchors.

Tip: Take a photo of the wiring before disconnecting. It helps if you need to reference it later.

Step 3: Prepare the Wiring for the Eufy Floodlight

Now that the old fixture is gone, it’s time to prepare the wires for your new eufy floodlight. Proper wiring ensures safe and reliable operation.

Strip the Wire Ends

Use a wire stripper to remove about ½ inch of insulation from the ends of the black, white, and ground wires. This exposes fresh copper for a solid connection.

Check Wire Length

Ensure each wire is long enough to reach the terminals on the eufy floodlight. If they’re too short, carefully pull more wire from the junction box or use wire extenders.

Twist the Strands (If Stranded Wire)

If your home uses stranded wire (multiple thin strands), twist the ends gently with pliers to keep them neat and prevent fraying.

Note: The eufy floodlight works with standard 120V AC power. Make sure your home’s voltage matches.

Step 4: Mount the Eufy Floodlight Bracket

The mounting bracket holds the floodlight securely in place. Proper alignment ensures optimal lighting and camera coverage.

Position the Bracket

Hold the bracket against the wall where you want to install the light. Use a level to make sure it’s straight. Mark the screw holes with a pencil.

Drill Pilot Holes

If mounting to wood, drill pilot holes slightly smaller than the screws. For brick or concrete, use a masonry bit and wall anchors.

Secure the Bracket

Align the bracket with the holes and screw it into place. Use a drill or screwdriver, but don’t overtighten—this can crack the bracket or wall.

Pro Tip: Choose a location at least 7–10 feet high for better motion detection and wider coverage. Avoid pointing the camera directly at the sun or bright lights.

Step 5: Connect the Wires

This is the most critical step. Correct wiring ensures your eufy floodlight powers on and functions safely.

Match the Wire Colors

• Black wire (hot) → Connect to the black wire from the floodlight
• White wire (neutral) → Connect to the white wire from the floodlight
• Green or bare wire (ground) → Connect to the green or bare wire from the floodlight

Twist and Secure with Wire Nuts

Hold the matching wires together and twist them clockwise with pliers. Screw on a wire nut until tight. Give each connection a gentle tug to ensure it’s secure.

Wrap with Electrical Tape

For extra protection, wrap each wire nut and connection with electrical tape. This prevents moisture from entering and adds strain relief.

Safety Reminder: Never leave bare wires exposed. All connections must be covered with wire nuts and tape.

Step 6: Attach the Floodlight to the Bracket

With the wires connected, it’s time to mount the floodlight itself. This step is straightforward but requires careful handling.

Align the Floodlight

Hold the eufy floodlight up to the bracket. Slide it into place so the mounting holes line up.

Screw It In

Use the provided screws to secure the floodlight to the bracket. Tighten just enough to hold it firmly—don’t overtighten, as this can damage the housing.

Adjust the Angle

Loosen the adjustment knobs (if applicable) to tilt the lights and camera. Aim the lights downward to illuminate your walkway or driveway. Point the camera where you want motion detection (e.g., front door, backyard).

Tip: Test the angle before fully tightening. You can always adjust it later, but it’s easier now.

Step 7: Restore Power and Test the Light

Now that everything is connected and mounted, it’s time to power up and see if it works.

Turn the Breaker Back On

Go to your electrical panel and switch the breaker to “ON.” Wait a few seconds for the system to stabilize.

Check for Light

The floodlight should turn on automatically if it’s in test mode or if motion is detected. If it doesn’t light up, turn off the power and double-check your wiring.

Use the Voltage Tester Again

Confirm the fixture is receiving power. If the light still doesn’t work, revisit the connections.

Note: Some eufy models have a physical power switch or require app activation. Check your user manual.

Step 8: Set Up the Eufy Security App

The app is where you control your floodlight, view footage, and customize settings. Setup is quick and user-friendly.

Download the App

If you haven’t already, download the eufy Security app from the App Store (iOS) or Google Play (Android). Create an account or log in.

Add Your Device

Tap the “+” icon and select “Add Device.” Choose “Floodlight Cam” from the list. The app will search for nearby devices.

Scan the QR Code

Point your phone’s camera at the QR code on the back of the floodlight or in the manual. The app will recognize the device and begin pairing.

Connect to Wi-Fi

Enter your 2.4GHz Wi-Fi network name and password. The floodlight will connect to your network. Avoid 5GHz networks—most eufy models don’t support them.

Name Your Device

Give your floodlight a name, like “Front Yard Light” or “Back Porch Cam.” This helps if you have multiple devices.

Pro Tip: Keep your phone close to the floodlight during setup for a stronger signal.

Step 9: Customize Settings and Features

Once connected, explore the app to unlock the full potential of your eufy floodlight.

Adjust Motion Detection

Go to “Device Settings” > “Motion Detection.” Set sensitivity levels and detection zones. For example, ignore motion from trees but alert you for people near the door.

Set Lighting Schedule

Choose when the lights turn on and off. Options include “Always On,” “Motion Activated,” or “Scheduled” (e.g., dusk to dawn).

Enable Two-Way Audio

Talk to visitors or deter intruders using the built-in microphone and speaker. Test it by saying “Hello” and listening for a response.

Review Recordings

Check the “Events” tab to see motion-triggered clips. Videos are stored locally on the device—no cloud fees.

Bonus: Enable “Human Detection” to reduce false alerts from animals or moving shadows.

Step 10: Weatherproof and Secure the Installation

Outdoor electronics need protection from rain, snow, and extreme temperatures. A few extra steps ensure long-term reliability.

Seal Wire Connections

Apply a small amount of silicone sealant around the wire nuts and entry points. This prevents water from seeping into the junction box.

Check for Gaps

Make sure the floodlight sits flush against the wall. Use caulk to fill any gaps between the fixture and the mounting surface.

Tighten All Screws

Double-check that all mounting screws are secure. Vibrations from wind or nearby traffic can loosen them over time.

Maintenance Tip: Clean the camera lens and light covers every few months with a soft, dry cloth.
