Eufy Floodlight Cam E340 test: Scope of delivery

The scope of delivery is quite extensive and, in addition to the necessary surveillance technology, also includes tools for installation. Here you will find the Floodlight Cam E340, USB cable, drilling template, screws, wall plugs, mounting strap with installation hooks and a quick-start guide.

Eufy Floodlight Cam E340 test: design and workmanship

What you see is what you get? This is definitely the case with the Floodlight E340. After all, it becomes clear as soon as you unpack it that this camera really wants to keep an eye on everything. Even in the dark thanks to the two floodlights. With dimensions of 321 x 187 x 216 mm and a weight of over 1.3 kg, the smart home gadget is by no means a compact surveillance camera.

If that’s too big for you, Eufy also has other models on offer. The Eufy SoloCam S220 (test), for example, is a compact camera from the Anker subsidiary. However, the dimensions also reflect a certain robustness. According to the manufacturer, you get protection in accordance with the IP65 standard. This means you don’t have to worry about damaging ingress of dirt and water.

The camera is also resistant to temperatures. It should be able to work at temperatures between -20°C and 50°C without any problems. With its stylish matt white housing, the Floodlight E340 is not just visually appealing. The build quality is also really excellent. However, experience has shown that this is one of Eufy’s specialties.

Eufy Floodlight Cam E340 test: Installation

The Floodlight E340 requires a power connection. It does not come with a rechargeable battery. If you don’t want to do without this flexibility, you should take a look at the Eufy S330 (test) or SoloCam S340 (test). However, if you have already connected a lamp and held a drill in your hands, mounting the camera is no problem.

If you have never done this before and have certain reservations, it is better to ask your friends and acquaintances or your trusted electrician. With a little skill and diligence, it won’t take more than a quarter of an hour before the surveillance camera is hanging in its intended location.

This is also thanks to Eufy for two key reasons. Firstly, the Anker subsidiary includes the tools required for installation in the form of screws, plugs and a drilling template. Furthermore, the app provides you with foolproof step-by-step instructions to help you with installation.

Eufy Floodlight Cam E340 test: Setup

Once the camera has found its place of use, the next step takes you to the Eufy Security app. Here you need to add the Floodlight E340 as a new gadget. This is anything but witchcraft and is even easier than the installation. Especially if you already have an Eufy account, the setup process is extremely quick.

You have two options when setting up the camera. On the one hand, you can connect the camera to your router independently and thus transfer it to the home network via a 2.4 or 5.0 GHz connection. However, if you own a HomeBase S380 (test), you can simplify this step considerably. In this case, the base ensures that the camera is connected to the Internet at lightning speed.

But these are not the only advantages you get when you use the Eufy control center. We’ll explain what else is available later. As soon as the camera has been added via the app, you can see it on the Eufy Security start page. The last image taken is displayed. For more detailed settings, simply click on the camera.

Eufy Floodlight Cam E340 test: Eufy Security App

The Eufy Security App is essential for operation. Of course, the Floodlight E340 also scores with a great overview and many setting options. The latter can be accessed by clicking on the cogwheel. Here you can make fine adjustments to the camera, motion detection, lighting, audio performance and other parameters.

The first thing you should do is set the camera’s field of view. If it is pointing towards the public space or a neighboring property, you must hide these areas. The end result is that the camera blacks out the area you have selected, which enables operation in accordance with the General Data Protection Regulation (GDPR).

However, if you do not want motion detection for certain areas, you do not have to provide the camera with a blind area. Instead, you can define areas specifically for motion detection that are to be recorded by the camera and others that are not.

Alternatively, you can also reduce the range of the corresponding sensor. This detects movements at a distance of up to 12 meters and can be adjusted in five stages. It is also possible to filter certain movements, as the camera can differentiate between pets, people and vehicles.

If you only want to be alerted to human movement in a garden area, for example, this can be easily implemented in the app. The orientation of the camera can also be adjusted. To do this, you can simply swivel it via the app. There is also a practical motion tracking function.

In this case, the camera automatically tracks a movement and then returns to the starting position. Of course, you can also adjust the power of the two floodlights. The brightness can be adjusted to suit your mood.

Eufy Floodlight Cam E340 test: Camera quality

The Floodlight E340 not only comes with two floodlights. It also comes with two lenses. Firstly, there is a wide-angle lens with a resolution of 2,880 x 1,620 pixels.

On the other hand, there is a telephoto lens with a resolution of 2,304 x 1,296 pixels. In daylight, the two lenses work together to produce really good-looking images that impress with their detail and vivid colors. I was particularly surprised when I used the zoom function.

Actually, I would have expected a single pixel mash here. But that wasn’t the case. Instead, you get razor-sharp results here too. It’s not just the daytime shots that are stylish. At night, the camera provides really impressive night vision in color with the help of the integrated lighting.

When the lights switch on, this not only makes for cool night shots. The two LED units can also be used as attractive lighting for patios or other outdoor areas. You can simply activate them permanently for this purpose. Then they don’t just light up when motion is detected. You can even set a schedule for the lighting in the app.

Eufy Floodlight Cam E340 test: AI features with HomeBase S380

On top of this, the lighting also fulfills a major security aspect. If you make full use of the powerful 2,000 lumen brightness, uninvited visitors will quickly leave your property. If that’s not enough, simply switch on the alarm siren with a maximum volume of 100 dB. The corresponding loudspeaker is also used for two-way audio together with the integrated microphone.

The intercom function works very well. Of course, you shouldn’t expect any acoustic miracles here, but it’s certainly good enough for brief communication with a visitor. If you want to get the most out of the Floodlight E340, you should consider buying a HomeBase S380. This makes the camera even smarter. And thanks to exciting AI features.

This is made possible by BionicMind facial recognition, which ensures that you can use so-called cross-camera video surveillance, for example. Here, the E340 automatically recognizes intruders together with other cameras from the Eufy system and records them. The HomeBase then automatically cuts together an overall video from the various individual recordings.

But BionicMind is also an exciting feature apart from this tracking function. The camera can recognize previously registered people and send you a corresponding message when they are on the property. If you are expecting visitors, this is a practical feature. The whole thing is currently still in beta and sometimes prone to errors. However, as it is a self-learning AI, the future promises to be better.

Eufy Floodlight Cam E340 test: video storage and smart home

When it comes to video storage, you have the choice between local storage and video storage in the Eufy Cloud. However, the cloud is associated with additional monthly costs, which is why you should definitely opt for the device storage. Up to 128 GB can be stored locally in the E340 using microSD. If this is not enough for you, you can use the HomeBase for more storage.

Up to 16 TB of storage space is possible here. You should definitely be able to record some moving images. Large-scale video recordings are also possible with the E340 together with the HomeBase S380. Finally, just like the E330 (Professional) (test), the video camera enables 24/7 video recording of the garden, front garden or front door around the clock.

Unfortunately, the gadget is not all that smart when it comes to smart home connectivity. Amazon Alexa and Google Assistant are available as voice assistants. Apple HomeKit and Samsung SmartThings are unfortunately left out here, as is the ONVIF system. Friends of cross-manufacturer smart home solutions should keep this in mind if they are interested in the E340.


The Eufy Floodlight E340 not only scored points in the test with its cool design and great workmanship. The heart of the device also shines: the camera unit. I was really pleasantly surprised by the recordings in 3K resolution. In combination with the powerful lighting, you get beautiful shots in color even at night.

Thanks to the rotatable design and 360° field of view, you always have everything in view. The AI features are also cool, which are enhanced by practical face recognition in conjunction with the HomeBase. The separate control center also enables up to 16 TB of local storage and 24/7 video recording. Unfortunately, where there is light, there is also shadow.

And with the Floodlight E340, this is unfortunately the smart home connection. Apart from Amazon Alexa and Google Assistant, you don’t get any other voice assistants here. It would be nice if Eufy would open up to other systems in the future through updates. If that doesn’t bother you, you’re getting a really good surveillance camera that is well worth its proud price.

The Eufy Floodlight Cam E340 scores with great camera quality, powerful lighting and ease of use. Unfortunately, it lacks smart home openness.
