Eufy Security Floodlight Camera E340 vs S330 Review

I previously reviewed and used the excellent Eufy Security Floodlight Cam 2 Pro, now called the Eufy Floodlight Camera S330, for the past two years. Eufy has now released the new Eufy Floodlight Camera E340, which I had the opportunity to beta test.

The E340 introduces several upgrades over the S330, most notably the addition of a second telephoto lens for 3x zoom. However, the S330 retains some advantages like increased brightness. In this review, I will compare the two models and examine if the E340 is a worthy upgrade or not.

Eufy Floodlight Camera E340 vs S330 – Spec Comparison

Oddly, the E340 has an RRP of £220, while the older S330 is £279. The E340 appears superior in most areas, though not all. Below is a comparison of the key specs:

Eufy Floodlight Camera E340 Pros:

  • Dual camera system
    • Improved 3K resolution main camera
    • Additional 2K telephoto camera with 3x zoom
  • On-device human/vehicle/pet detection vs just human
  • Compatible with HomeBase S380 from launch
    • Enables facial recognition
  • microSD support up to 128GB vs 8GB eMMC
  • 24/7 recording option
  • WiFi 6 and 5GHz band vs WiFi 5 and 2.4GHz only

Eufy Floodlight Camera S330 Pros:

  • Three adjustable floodlight panels with 3000 lumens vs 2000 fixed
  • Adjustable light temperature from 3000°K to 5700°K vs fixed 4000°K

Design and Build Quality

The E340 has a very different design to the S330. The S330 showed signs of wear after 2 years, but fared better than the EZVIZ LC1 it replaced.

The E340 lacks a protective dome over the lens, but Eufy claims the lenses are scratch-proof. I haven’t had any issues so far.

The mounting system is also changed. The S330 had a folding base, while some users reported water build up on the flat top. The E340 may address this by removing the dome and changing the mount.

The E340 has 2 floodlight panels vs the 3 on the S330. This may contribute to the lower 2000 lumen rating.

Overall build quality seems on par between both models. The dual camera design is the most obvious difference.

Set Up and Installation

You can set up the E340 before mounting, allowing you to test operation first. The camera connected directly to my WiFi during beta testing as HomeBase S380 support was pending.

Installation was relatively easy, taking around 30 minutes. Running cables is trickier than a fully wireless option, but still straightforward. The foam padding on the S330 gave a bit more flexibility when mounting.

Those with existing wiring may have an easier time, but the E340 should be simple enough for most people comfortable with basic DIY tasks.

Wi-Fi Connectivity

The E340 has upgraded WiFi capabilities, now supporting WiFi 6 and 5GHz for faster speeds and more responsive notifications.

When connecting to HomeBase S380, the camera uses the hub’s WiFi signal rather than your home WiFi. In my case, this led to slightly worse signal strength. But I haven’t experienced any major connectivity or notification delays.

Smart Home Integration

Like most security cameras, third-party integration is limited. You have support for Amazon Alexa and Google Assistant, but that’s it.

Apple HomeKit, RTSP feeds, and Home Assistant integrations are not available. This is disappointing, as Eufy previously supported HomeKit. Those using other smart home ecosystems may want to consider alternative options.

App Features and Settings

Storage Options

The E340 has two storage options – microSD card up to 128GB, or the HomeBase S380 hub. microSD works with 24/7 recording, but an endurance card is recommended for constant writes.

The HomeBase S380 has 16GB built-in, plus a 2.5″ SATA drive bay supporting up to 16TB. However, 2.5″ HDDs only reach 5TB currently. The HomeBase also enables advanced AI detection and facial recognition.

Motion Detection and Tracking

Human detection allows the camera to automatically track movement, panning and tilting to follow subjects. The telephoto lens complements tracking nicely by capturing clear details of faces and clothing.

False motion alerts are a common downside of AI detection. My camera sometimes flags hanging laundry as human. But recent firmware updates have reduced other false positives.

Auto Cruise / Patrolling

You can set the camera to patrol by panning between three preset positions. This expands the monitoring area for larger properties.

I tried patrolling briefly but it picked up my neighbor’s garden unnecessarily. For my small property, tracking detected motion is more useful.

Image Quality

Daytime Footage

With both lenses active, footage is captured at 2304×2592 resolution. The 3x zoom causes some jerkiness when panning and tilting. Lowering the speed helps, but risks slower tracking.

Overall daytime video is excellent for a WiFi camera. 24/7 recording lets you scroll back through timeline history and download clips.

Night Vision

Without the floodlights, night footage is black and white as expected. Quality is decent but lacks color detail.

Turning the floodlights on enables color nighttime recording. The 2000 lumen rating provides ample illumination for my small garden. Larger areas may benefit from the S330’s 3000 lumens.

While resolution is good, the sensor technology doesn’t match dedicated security cameras using 1/1.8″ sensors and f/1.0 apertures. But those models lack other features of the E340.

Pricing and Alternatives

With an RRP of £220, the Eufy Floodlight Camera E340 costs £60 less than the older S330. The upgrades like the dual-lens appear well worth the price.

The Reolink Duo Floodlight PoE is a compelling alternative at around £150. It lacks zoom but has higher 8MP resolution and 180° FOV.

For a similar dual-lens design, the Reolink TrackMix PoE costs under £170. It has a spotlight instead of floodlights, but no battery power.

Finally, the Arlo Pro 3 Floodlight is the only other battery-powered floodlight camera I’m aware of. It costs between £120-£150 typically.


The Eufy Floodlight Camera S330 has been my favorite floodlight security camera for the past 2 years. In my testing, the new E340 improves upon it in most areas, including the handy dual-lens zoom functionality.

Upgraded features like HomeBase S380 support, 24/7 recording, and higher resolution are also great to have. The reduction in floodlight brightness could be an issue for large properties or sparse lighting.

But for my needs, the 2000 lumen output is sufficient. While the S330 remains an excellent choice, I think the E340 is worth the upgrade for most users needing a solid WiFi floodlight camera system. It beats much of the competition through a compelling mix of hardware, software, and value.
