  • Dual camera lenses (wide-angle and telephoto zoom)
  • 360° horizontal panning rotation
  • Enhanced low-light video quality
  • AI-powered motion tracking
  • Continuous color recording (24/7)
  • Higher 2K and 3K resolution
  • Brighter 2000-lumen flood lights

In a nutshell, it is an integrated lighting and monitoring solution for home and business security applications. The bright floodlights deter intruders and illuminate the premises while the swiveling dual-lens camera records activity day and night.

Now let’s explore all aspects of this intelligent camera in detail so you know exactly what it offers.

Unboxing and Contents

The Floodlight Cam E340 comes neatly packed in a compact cardboard box with product images and specs printed on the sides and rear.

Opening it up reveals compartments holding:

  • The E340 camera/light unit
  • Mounting base plate
  • Hardware mounting kit
  • Power wiring harness
  • Accessory box

The accessory box contains:

  • Safety documentation
  • Positioning template
  • Screws, anchors, wire nuts
  • Installation hook
  • Short charging cable (USB A to USB C)

So everything you need for installation comes included. You just need to supply the junction box, wires to connect with the electrical supply and tools for mounting.

Now let’s look at how the actual device is constructed.

Physical Construction and Design

The eufy Floodlight Cam 340 has a durable polyethylene plastic housing that encases the cameras, sensors, speakers, and other internal circuitry.

The front face features:

  • A pair of large rectangular LED floodlight panels
  • Central speaker grille
  • Prominent passive infrared (PIR) motion sensor
  • Dual camera lenses with status light ring

The floodlight panels have heat sink fins on the back to dissipate heat. Their angle can be adjusted manually upward, downward, and sideways to aim the light beam optimally.

The dual camera assembly sits in the middle and can pan 360° horizontally or tilt 60° vertically for complete coverage – more on that later.

On the underside, a removable rubber-sealed panel protects:

  • Button to sync with WiFi
  • Slot to insert MicroSD card
  • USB-C port for charging and firmware updates

Having these controls tucked away out of sight and weather makes it very tamperproof.

The camera unit connects to the base plate through a wired harness already pre-attached internally to simplify installation. The base has holes to mount it on any standard electrical junction box recessed in a wall or ceiling. 

There are also openings to feed electrical wires from your junction box into the camera.

The housing has an IP65 ingress rating, meaning it is dust-tight and can withstand low-pressure water jets. 

So you can install it outdoors without worrying about dirt, rain, snow, or moderate water spray damaging the internals.

It can operate in temperatures from -4° to 122° Fahrenheit / -20° to 50° Celsius.

Overall, eufy designed the Floodlight Cam E340 to be a rugged, weather-resistant outdoor security solution. 

Next, we dive into the brains behind its intelligent monitoring capabilities.

Hardware Specifications

Let’s geek out on what powers this high-tech floodlight camera! 

Here are the key hardware specs:

eufy Dual Cam

The ability to view a scene both zoomed-out and zoomed-in simultaneously is game-changing. The E340 accomplishes this with two camera lenses.

  • Main: 3K resolution (2880 x 1620 pixels) recorded at 15 fps. The lens has an extra-wide 135° diagonal field of view for the overall picture.
  • Telephoto: 2K resolution (2304 x 1296 pixels). It provides 3X optical magnification plus an additional 5X digital zoom for 8X total magnification. Very useful to read license plates, recognize faces, etc from a distance.
8X digital zoom

Both lenses have brightness ƒ/1.6 aperture ratings for great low-light performance.

Wide Angle3K (2880 x 1620)ƒ/1.6135° Diagonal
Telephoto2K (2304 x 1296)ƒ/1.6,
3X Optical Zoom

Rotating Camera Assembly

As mentioned previously, the entire cylindrical camera and floodlight unit can spin 360° horizontally and tilt 60° up/down. This lets you scan in all directions and eliminates any blind spots in coverage.

The smooth panning also facilitates advanced AI tracking of subjects we will cover later.

Flood Lights

The Floodlight Cam E340 features two rectangular LED flood panels with sturdy aluminum heat sinks to cool the back.

Specs include:

  • 2000 lumens peak brightness (at 4000K neutral white)
  • Adjustable up to 180° vertically and 270° horizontally
  • Color rendering CRI > 80 for accurate color video
  • Operating power 36W
2000 lumens peak brightness (at 4000K neutral white)
2000 lumens peak brightness (at 4000K neutral white)

So very versatile, high output lighting matched with the camera’s impressive low light sensitivity results in superb night vision.


The E340 has an Ethernet port for wired connectivity. It supports the latest WiFi 6 protocol (802.11 ax) on both 2.4 GHz and 5 GHz bands for solid transmission quality and speeds up to 1.2 Gbps.

Modern WPA3 WiFi encryption provides strong protection against hacking of your video feeds.

Local Storage

The camera has an internal eMMC flash memory chip for caching video footage without requiring an external microSD card. Capacity is 8GB, letting you store about 1 week of motion event clips normally.

You can add a microSD card up to 128GB for more extensive continuous recording history if desired. Roughly 45 days of 24/7 video at full 3K resolution based on motion event frequency in typical installations.

This local storage is perfect for privacy-conscious users cautious about video feeds leaving their premises. But more extended cloud backups remain an option too.

Now that we understand the Floodlight Cam E340’s construction and capabilities at a technical level, let’s see how we can install and interface with it.

Setting Up the eufy Security App

eufy has a dedicated Security app to configure and control the Floodlight Cam remotely from your smartphone. It is available for both iOS and Android mobile devices.

To set up a new camera on the network:

  • Download and launch the eufy security app
  • Click the Plus icon to add a new device
  • Select the Floodlight Cam E340 from the device models

  • Use the rear QR code to automatically scan device details
  • Plug the camera in close by using the short USB cable and power adapter
  • Press the Sync button to initiate networking handshake while the status light spins
  • Follow remaining onscreen prompts to select WiFi network and enter password
  • Wait several minutes for firmware installation and synchronization

Once done, you will see live video feeds from the dual lenses! The camera should now be fully operational and connected wirelessly to your home network.

Next, we will cover hardware installation…

Installation of the Camera

Since the eufy Floodlight Cam E340 has an electrical load of 36W, it needs proper permanent wiring.

Tools Needed

  • Drill with various-sized bits
  • Philips screwdriver
  • Electrical tester
  • Wire cutters, strippers, crimper
  • Ladder

Mounting Options

You have two choices to physically install the camera:

  1. Wall mount
  2. Ceiling mount

Wall Mounting Steps

Wall mounting is easiest as the flatter base plate better facilitates drilling pilot holes and running wires.

  • Mark hole positions on wall using the included template
  • Drill pilot holes for anchors at desired height (ideally 8-10 feet)
  • Drill or hammer drill a 1-inch diameter pass-through hole for wires
  • Feed building wiring through pass-through to outdoor junction box
  • Anchor junction box to wall/studs as needed
  • Match wire colors – connect black (hot), white (neutral) and green ground
  • Secure base plate centered over the junction box
  • Insert mounting hook into base slot
  • Hang floodlight camera temporarily on hook
  • Connect building wires to camera wires with provided waterproof splice caps
  • Mount camera with hook removed onto anchored base plate

And you will have rock solid installation!

Ceiling Mounting

For under eave positioning:

  • Remove the screw holding the wiring harness
  • Flip the harness top-side-up
  • Reattach harness screw
  • Attach included S hook through harness slot instead of wall plate
  • Feed wires from junction box and splice connections as with wall mounting
  • Flange of base plate will be on ceiling with camera suspended

The quarter twenty threaded hole on top allows attaching a conduit fitting to cleanly route wires if needed.

Here is a step-by-step visual guide on how to do these – 

With the electricals and physical mounting covered, let’s look at the settings…

eufy App Settings and Customization

In the eufy Security app, you can access and configure various options via the Settings icon (a gear symbol). We will highlight some popular settings.

Light Settings

The 2000-lumen LED floodlights are a defining feature. Convenient presets include:

  • Manual On/Off Control
  • Motion-Activated Illumination
  • Ambient Lighting with Scheduling
  • Sunset to Sunrise automated behavior based on ambient brightness

You can also tweak parameters like:

  • Brightness percentage
  • Color temperature
  • Duration after motion trigger
  • Fade-in/out transition effects

So very customizable lighting schemes tailored to your exact needs and preferences!

Motion Detection

This section has extensive tuning capabilities such as:

  • Activity zones – Limit detections to 1 or 2 specified rectangular regions rather than the entire view. Useful for ignoring repetitive background motion while still covering areas of interest.
  • Detection Type – Human, pet, vehicle or all motion
  • Sensitivity – Higher values pick up smaller motions while low values filter out faraway nuisances
  • Out-of-View Detection – Automatically pans camera if side/rear motion is sensed
  • Detection Range – Modify distance for motion alerts
  • AI Tracking – Locks onto and follows movement automatically (more later)

Recording Settings

By default, video clips get recorded only when the PIR sensor detects activity. But the round-the-clock recording has options for:

  • Continuous video
  • Scheduled intervals such as during business hours
  • Recording schedule – Select days and time spans
  • Video Length – Duration of recordings
  • Streaming Quality – Auto, HD or Highest
  • Local Storage overwritten or not when full

So set it based on monitoring needs – High-quality 24/7 recordings will fill the 128GB card in about a month. Lower resolution event-based recording provides 4-5X longer history.

Alert Notifications

Say you are on vacation and want to be alerted about suspicious activity picked up by the motion tracking intelligence.

You can configure notifications as:

  • Type – Human, vehicle or all
  • Push alert text message
  • Follow-up thumbnail image from the event
  • Interval between alerts – say 10 minutes

So only significant incidents sporadically notify rather than a barrage of texts!

The software settings lend incredible customization leeway to this security camera system. Now let’s see how the hardware performs in action…

Performance, Video, and Night Vision Quality

With installation and configuration complete, we can evaluate real-world performance.

Daytime Video

Image quality in full sunlight is crisp, vividly colored, and packed with detail. The 2880 x 1620 pixels of the wide-angle feed let you monitor a very broad area.

Switching to the narrower 2304 x 1296 telephoto display, it digitally zooms in by 3X to recognize faces or objects clearly at 50 feet away. Walking right up closer continues seamless focus.

The dual viewing modes avoid the pixelated distortion of inferior digital zoom attempts on single-lens cameras.

License plates are readable at surprising distances – matching some higher-priced 4K competitors!

Low Light Imaging

As dusk settles in, the Floodlight Cam E340 switches to night vision mode around 10-15 lux ambient light levels. The IR cut filter drops away allowing the image sensor to absorb more of the infrared spectrum.

You have dual options for monochrome or color low-light video. Color night vision is made possible by the camera’s high sensitivity plus the ample floodlight brightness when triggered.

With IR mode, the camera sees clear details in absolute darkness out to 60-80 feet depending on the lens used. Enabling auto IR achieves 30-40 feet detection distances exceeding most rival cameras. Remarkable reach considering a single LED spotlight is not concentrated in one fixed direction like Cam Plus models.

The 2000-lumen floodlights bathe areas in bright white light on demand. Activating them gives full-color imaging almost like daytime. From dark doorway shadows to the far end of a warehouse parking lot, precise colored details pop out.

The night vision performance is a top selling point over most comparably priced security cameras in the market currently.

Smart Motion Tracking and AI Capabilities

A standard camera passively monitors what happens in its field of view. eufy’s Floodlight Cam E340 ramps up the intelligence significantly.

The onboard software algorithms can discriminate between types of motion – human or vehicle. When such events occur, the camera springs smartly into action!

Auto Tracking

By default, the motion tracking feature automatically detects, zooms in, and follows movement of people or cars across its vision. A box outlines the tracked subject even as it travels into the periphery. The camera smoothly pans and tilts in sync keeping the subject accurately centered in frame.

No more blurry images of that suspicious individual fleeing the property since the camera ‘locks on’ to precisely track them. Excellent results also trailing cars cruising down the street.

You can define tracking sensitivity to avoid erratic focus bouncing with insignificant motions like swaying trees or minor lighting changes.

Out of View Detection

Cameras have limited viewing angles. Normally activity happening outside this cone goes unseen. eufy’s E340 employs radar-like technology to detect motion occurring even to the side or rear.

When such out-of-view activity is picked up, the camera will automatically spin around to bring that area into focus, act as a virtual eye watching all directions!

You can also configure Preset Positions – save specific pan/tilt coords and schedule timed viewing of multiple areas. This automated panning essentially acts as a moving sentinel surveilling everywhere.

Advanced motion analytics made easy! Let’s talk about storage…

Local and Cloud Storage Options

Cloud subscriptions for archiving security footage keep getting cheaper. But trusting your video data to third parties has privacy implications.

eufy designed the Floodlight Cam E340 to mitigate such concerns with generous local storage capacity – both integrated flash memory and external microSD card support.

Onboard eMMC chip

The camera contains an 8GB eMMC NAND flash memory chip storing about a week of motion event video clips normally. If connectivity drops, recent footage remains accessible.

microSD Card Slot

For more extended recording histories, just insert any standard microSD card up to 128GB capacity.

  • A 32 GB card (~$6) fits 2-3 weeks of 24/7 highest-quality video
  • With a 128 GB card (~$16), you can store a whopping 45 days worth based on average motion frequency!

So cost-effective long-duration local capture is ideal for small businesses or proprietary data uses.

HomeBase 3 Compatibility

Homebase 3 is an optional hub offered by eufy to enable additional capabilities like facial recognition, human shape detection, and pet recognition. It acts as centralized storage for streaming video from multiple security cameras.

Hooking up the E340 camera to a HomeBase 3 gives you:

  • MicroSD card recordings PLUS simultaneous backup to the HomeBase HDD
  • Up to 16 TB storage capacity
  • Enhanced AI motion alerts
  • Searchable footage timeline by date, human attributes, vehicles, pets etc.
Up to 16 TB storage capacity

With military-grade AES-256 video encryption, footage remains secure. HomeBase 3 works with Google Assistant and Amazon Alexa too!

So local and cloud storage options galore to suit needs and budgets.

Voice Assistant Compatibility

In this digital era, smart homes managed by voice are increasingly commonplace. eufy designed integration with popular assistants for controlling the Floodlight Cam E340.

Amazon Alexa

You can link the camera to your Alexa account and issue intuitive hands-free voice commands like:

  • “Alexa show me the front yard camera”
  • “Alexa turn on the front lights”
  • “Alexa activate garage camera tracking”

Google Assistant

Similarly, just link your Google account for voice operation such as:

  • “OK Google, dim the backyard floodlights”
  • “Show patio camera view on the bedroom TV”
  • “Turn off backyard camera motion alerts”

So convenient versus pulling out your smartphone each time!

Ease of Installation

We covered hardware mounting earlier. How tricky is the actual Camera setup?

In a word – Super easy! eufy made the process very straightforward for both wiring and WiFi connectivity.

The color-coded wires match typical home electrical conventions. Getting power is a case of twisting matching wires and tightening a few caps.

The proprietary eufy Security app has you entering WiFi details and scanning the QR code in under a minute. Subsequent calibration and tweaking settings are intuitive too.

Those less technically inclined need not worry – the Floodlight Cam E340 is designed for simplicity. The step-by-step in-app guidance combined with color-coded wiring and QR code scanning makes installation straightforward.

Within minutes, you can have the dual-lens camera streaming crisp video to your phone and ready to start monitoring activity seamlessly.

While positioning the floodlight, do heed the safety guidelines provided to avoid staring directly into the bright LEDs.

Angling and orienting the panels is easy with 180° vertical and 270° side-to-side flexibility. Pointing them downwards focuses ample light on desired spots only. No specialized tools needed whatsoever.

Lastly, ensure you mount the camera adequately high for subjects to comfortably walk beneath – usually 8 to 10 feet stands ideal. This facilitates reliable facial recognition by the telephoto lens as well.

So even if you hate fiddling with electronics, the Floodlight Cam E340 proves one of the most user-friendly security cameras to deploy. Just take sensible precautions against water or shock hazards when dealing with electrical systems.

Now let’s examine how the E340 compares with competitor models. Here’s the continuation of the article:
