What’s in the Box?

Before you begin, make sure you have all the components that come with your Eufy E340 floodlight camera. Here’s what should be included:

• Eufy E340 floodlight camera unit
• Mounting bracket
• Screws and wall anchors
• Wire nuts (usually black or yellow)
• User manual and quick start guide
• Safety gloves (in some packages)

If anything is missing or damaged, contact Eufy customer support immediately. It’s also a good idea to check the model number to ensure you have the correct version (E340, not E340 Pro or other variants).

Tools and Materials You’ll Need

While the E340 comes with most hardware, you’ll need a few basic tools to complete the installation:

• Screwdriver (Phillips head)
• Wire stripper
• Voltage tester (non-contact)
• Ladder (stable and tall enough to reach the installation spot)
• Electrical tape
• Pencil or marker
• Drill (if mounting into brick, concrete, or hard surfaces)
• Safety goggles and gloves

Having these tools ready will save time and prevent frustration. If you don’t own a voltage tester, consider borrowing or purchasing one—it’s essential for confirming the power is off.

Step 1: Choose the Right Location

The placement of your Eufy E340 is crucial for optimal performance. Here’s what to consider:

Ideal Mounting Height

Mount the camera between 8 and 10 feet above the ground. This height provides a wide field of view while minimizing the risk of tampering. Avoid placing it too high, as it may reduce image clarity and motion detection accuracy.

Field of View

Choose a spot that covers key areas like driveways, front doors, backyards, or side entrances. The E340 has a 130-degree diagonal field of view, so position it to capture the most activity. Avoid pointing it directly at bright lights or reflective surfaces, which can cause glare.

Power Source Access

The E340 must be hardwired to your home’s electrical system. Ensure the installation location has existing wiring from a previous floodlight or junction box. If not, you may need to run new wiring—this is best left to a licensed electrician.

Wi-Fi Signal Strength

Since the camera connects to your home Wi-Fi, test the signal at the installation spot. Use your phone or a Wi-Fi analyzer app to check for strong connectivity. Weak signals can cause lag, dropped recordings, or failed alerts.

Weather Protection

While the E340 is weather-resistant (IP65 rated), avoid installing it in areas with constant direct exposure to heavy rain, snow, or extreme heat. Under an eave or overhang is ideal.

Step 2: Turn Off the Power

Safety first! Working with electricity can be dangerous, so always shut off power before handling wires.

Locate the Correct Circuit Breaker

Find the breaker that controls the existing floodlight or junction box. It’s usually labeled (e.g., “Front Porch Light” or “Exterior Lights”). If unsure, turn off the main breaker to be safe.

Test the Power

Use a non-contact voltage tester to confirm the power is off. Touch the tester to the wires in the junction box. If it beeps or lights up, the power is still on—double-check the breaker.

Leave a Note

Place a note on the breaker panel to warn others not to turn the power back on while you’re working. This prevents accidental shocks.

Step 3: Remove the Old Fixture (If Applicable)

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

Unscrew the Mounting Bracket

Use a screwdriver to remove the screws holding the old fixture to the wall or junction box. Support the fixture with one hand as you remove the last screw to prevent it from falling.

Disconnect the Wires

Carefully pull the fixture away to expose the wires. Unscrew the wire nuts and separate the wires. Note which wires are connected (typically black to black, white to white, and ground to ground).

Inspect the Junction Box

Check that the junction box is secure and in good condition. If it’s loose, rusted, or damaged, replace it before installing the E340.

Step 4: Prepare the Wires

Now it’s time to prepare the wires for the new installation.

Strip the Wire Ends

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

Twist the Strands

If the wires are stranded (multiple thin wires), twist them gently with your fingers to keep them neat and prevent fraying.

Check Wire Length

Ensure the wires are long enough to reach the E340’s connection points. If not, you may need to extend them with additional wire and wire nuts.

Step 5: Install the Mounting Bracket

The mounting bracket ensures the E340 is securely attached and properly aligned.

Position the Bracket

Hold the bracket against the wall or junction box. Use a level to make sure it’s straight. Mark the screw holes with a pencil.

Drill Pilot Holes (If Needed)

If mounting into wood, you can screw directly. For brick, concrete, or stucco, drill pilot holes and insert wall anchors.

Secure the Bracket

Align the bracket with the marks and screw it into place. Make sure it’s tight and doesn’t wobble.

Step 6: Connect the Wires

This is the most critical step—proper wiring ensures safety and functionality.

Match the Wires

Connect the wires as follows:

• Black (hot) wire from the wall to the black wire on the E340
• White (neutral) wire from the wall to the white wire on the E340
• Green or bare (ground) wire from the wall to the green or bare wire on the E340

Twist and Secure with Wire Nuts

Twist the matching wires together clockwise, then screw on a wire nut. Give each connection a gentle tug to ensure it’s secure. Wrap electrical tape around the wire nuts for extra protection.

Fold Wires into the Junction Box

Tuck the connected wires neatly into the junction box to avoid pinching or damage when mounting the camera.

Step 7: Mount the Eufy E340 Camera

With the wires connected, it’s time to attach the camera.

Align the Camera

Hold the E340 against the mounting bracket. Slide it into place so the screws align with the slots on the bracket.

Secure with Screws

Insert the provided screws through the camera and into the bracket. Tighten them evenly to avoid warping the housing.

Check Stability

Gently shake the camera to ensure it’s firmly attached. It shouldn’t move or wobble.

Step 8: Restore Power and Test

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

Turn the Breaker Back On

Go to the breaker panel and flip the switch to restore power. Wait a few seconds for the camera to initialize.

Check the Floodlights

The floodlights should turn on automatically or when motion is detected. If they don’t, double-check the wiring and breaker.

Listen for the Camera

You may hear a brief startup sound from the camera. This indicates it’s powering up correctly.

Step 9: Download and Set Up the Eufy Security App

The Eufy Security app is essential for controlling your camera, viewing live footage, and customizing settings.

Download the App

Search for “Eufy Security” in the Apple App Store or Google Play Store. Download and install it on your smartphone or tablet.
