Anker is introducing a number of new devices for the new year as part of its Eufy line of smart home appliances, including the Eufy Video Doorbell S4, the Eufy Smart Lock E40, and the Eufy Solar Wall Light Cam S4. New designs and upgraded features are some of the main attractions of this year’s models.
The Eufy Video Doorbell S4 has a clean, simple design, much improved from predecessors such as the FamiLock S3 Max. The 3K camera provides 9MP resolution and a 180-degree panoramic view of the area surrounding the door. A new AI protocol provides motion sensing and facial recognition. The doorbell can be powered by either battery or wiring and integrates with Alexa, Google Assistant, and Apple Home. It will be available in the first quarter of 2026 with a price of $249.
The Eufy Smart Lock E40 also offers a new, more elegant look. It is equipped with a 2K HD camera offering wide-angle coverage, night vision, and facial recognition. It is battery powered using a 15,000mAh main battery along with a built-in 800mAh backup. The E40 is compatible with Matter, so it can be used with a variety of systems from Apple, Amazon, Google, and others. It will also be available in the first quarter of this year for $299.
Finally, the Eufy Solar Wall Light Cam S4 provides a lot of security with its 4K night vision and F1.6 adjustable lens; pan and tilt means you can cover a wide area range. It comes with a detachable 2W solar panel that powers a 10,000mAh battery for, according to the company, up to two months of use. You can connect it with other Eufy devices for better coverage and use its AI features to recognize people, vehicles, or animals. It is compatible with a range of systems, including Apple Home, Alexa, and Google Home, and will be available in the first quarter of this year for $199.99.
