What You’ll Need Before Starting

Before you begin, gather all the tools and materials to avoid mid-installation trips to the hardware store. Here’s what you’ll need:

• Eufy E340 Floodlight Camera kit (includes camera, mounting bracket, screws, wire nuts, and template)
• Screwdriver (Phillips head)
• Drill and drill bits (typically 3/16″ for masonry or wood)
• Voltage tester (to confirm power is off)
• Ladder (stable and tall enough to reach the installation height)
• Wire strippers (if existing wires need trimming)
• Pencil or marker (for marking drill points)
• Smartphone or tablet with the Eufy Security app installed
• Wi-Fi network (2.4 GHz required; 5 GHz not supported)

Pro Tip: Check your local building codes. Some areas require permits for outdoor electrical work. When in doubt, consult a licensed electrician.

Step 1: Turn Off the Power

Safety first! Working with electricity can be dangerous if you don’t take proper precautions.

Locate Your Circuit Breaker

Go to your home’s main electrical panel (usually in the garage, basement, or utility room). Find the breaker that controls the outdoor light circuit you’re replacing. It may be labeled “Exterior Lights,” “Porch,” or something similar.

Switch Off the Breaker

Flip the breaker to the “OFF” position. To be extra safe, use a voltage tester on the existing fixture’s wires to confirm no electricity is flowing.

Important: Never assume the power is off just because the light doesn’t work. Always test!

Leave a Note

Place a sticky note on the breaker panel saying “DO NOT TURN ON – WORK IN PROGRESS.” This prevents someone else from accidentally restoring power while you’re working.

Step 2: Remove the Old Fixture (If Applicable)

If you’re replacing an existing floodlight or porch light, you’ll need to remove it first.

Unscrew the Mounting Bracket

Use your screwdriver to remove the screws holding the old fixture to the wall or junction box. Gently lower the fixture to expose the wires.

Disconnect the Wires

You’ll typically see three wires: black (hot), white (neutral), and green or bare copper (ground). Unscrew the wire nuts and separate the wires.

Remove the Old Bracket

Unscrew and remove the old mounting bracket from the junction box. Clean any debris or old caulk from the area.

Tip: Take a photo of the wiring before disconnecting. This can help if you get confused later.

Step 3: Prepare the Mounting Area

Now it’s time to get the wall ready for the Eufy E340.

Use the Included Template

The Eufy kit includes a paper mounting template. Hold it against the wall where you want to install the camera. Make sure it’s level using a spirit level.

Mark the Drill Points

Use a pencil to mark the center of each screw hole through the template. Remove the template.

Drill Pilot Holes

Drill pilot holes at the marked spots. Use a drill bit slightly smaller than the provided screws for a snug fit.

Note: If mounting on brick or concrete, use a masonry bit and wall anchors. The kit includes anchors, but you may need longer ones for heavy walls.

Step 4: Install the Mounting Bracket

The Eufy E340 uses a sturdy metal bracket to secure the camera.

Align the Bracket

Hold the bracket over the pilot holes. Make sure it’s level and centered.

Secure with Screws

Insert the provided screws through the bracket and into the wall. Tighten them firmly, but don’t over-tighten—this can strip the holes.

Check Stability

Give the bracket a gentle tug. It should feel solid and not wobble.

Pro Tip: Apply a small bead of outdoor silicone sealant around the edges of the bracket to prevent water from seeping behind it.

Step 5: Connect the Wires

This is the most critical step. Correct wiring ensures the camera and floodlights work safely.

Identify the Wires

From your junction box, you should have:
– Black wire (hot)
– White wire (neutral)
– Green or bare copper wire (ground)

The Eufy E340 has matching wires:
– Black (hot)
– White (neutral)
– Green (ground)

Strip the Wire Ends (If Needed)

If the wire ends are frayed or too short, use wire strippers to expose about 1/2 inch of copper.

Connect the Wires

Match the colors:
– Black to black
– White to white
– Green to green (or ground wire from the junction box)

Twist the matching wires together clockwise, then secure each pair with a wire nut. Give each connection a gentle tug to ensure it’s tight.

Tuck Wires into the Junction Box

Carefully push the connected wires back into the junction box. Don’t force them—this can loosen connections.

Safety Reminder: Never leave exposed wire. All connections must be covered with wire nuts.

Step 6: Attach the Eufy E340 Camera

Now it’s time to mount the camera onto the bracket.

Align the Camera

Hold the Eufy E340 against the bracket. The camera should slide into place with the mounting holes lining up.

Secure with Screws

Insert the provided screws through the camera’s base and into the bracket. Tighten them evenly to avoid tilting.

Adjust the Angle

The E340 allows you to tilt the camera up, down, left, or right. Position it to cover your desired area—like your driveway, front door, or backyard.

Tip: Aim the camera slightly downward to reduce glare from the floodlights and improve motion detection.

Step 7: Power On and Test

You’re almost done! Now it’s time to restore power and test the system.

Turn the Breaker Back On

Go to your electrical panel and flip the breaker to “ON.”

Check the Floodlights

The floodlights should turn on automatically. If they don’t, double-check your wiring.

Listen for the Camera

You should hear a soft beep or chime from the camera, indicating it’s powering up.

Note: The camera may take 30–60 seconds to fully boot up. Be patient!

Step 8: Set Up the Eufy Security App

The Eufy app is your control center for the camera. Download it from the App Store (iOS) or Google Play (Android) if you haven’t already.

Create an Account

Open the app and tap “Sign Up.” Enter your email, create a password, and verify your account.

Add a New Device

Tap the “+” icon and select “Add Device.” Choose “Floodlight Camera” and then “E340.”

Scan the QR Code

The app will ask you to scan the QR code on the camera’s label (usually on the back or bottom). Point your phone’s camera at the code.

Connect to Wi-Fi

Follow the on-screen prompts to connect the camera to your 2.4 GHz Wi-Fi network. Enter your Wi-Fi password when prompted.

Wait for Pairing

The camera will connect to your network. This may take 1–2 minutes. You’ll see a confirmation message when it’s done.

Tip: Keep your phone close to the camera during setup for a strong signal.

Step 9: Customize Settings

Now that your camera is online, personalize it to fit your needs.

Adjust Motion Detection

Go to “Device Settings” > “Motion Detection.” You can:
– Set sensitivity (low, medium, high)
– Define motion zones (ignore trees or sidewalks)
– Choose detection types (people, vehicles, packages)

Set Up Activity Zones

Draw zones on the camera’s view where you want alerts. For example, focus on your front door but ignore the street.

Configure Floodlight Settings

Under “Light Settings,” you can:
– Set brightness (low, medium, high)
– Choose when lights turn on (dusk to dawn, always on, or motion-activated)
– Adjust the duration (how long lights stay on after motion)

Enable Two-Way Audio

Test the microphone and speaker by tapping the talk button in the app. Speak and listen for clear audio.

Set Up Alerts

Choose how you want to be notified: push notifications, email, or both. You can also set quiet hours to avoid nighttime alerts.

Step 10: Final Checks and Maintenance

Before you call it a day, do a final inspection.

Test the Camera Feed

Open the app and watch the live view. Check for:
– Clear video quality
– Proper angle and coverage
– Working night vision (cover the lens to test)
