If you’ve been looking for a security camera that works where wifi doesn’t reach, the Eufy Security 4G LTE Cam S330 might be the one to consider. Currently, it’s selling for $161.49, down from its usual price of $249.99 on Amazon.
Like the rest of Eufy’s Solocam line, it avoids the subscription fees that many competitors lock you into. Instead, you can save clips locally on the included microSD card, or if you’re using it on wifi, you can connect it to the Eufy HomeBase S380 for local storage. That makes the S330 a good fit if you want full functionality without committing to another monthly bill. Eufy ships the camera with an EIOT SIM and 100GB of data to test the 4G features.
The S330 builds on the wireless S340 with the same dual-lens setup—a wide-angle macro lens paired with a close-up micro lens. The combination lets you cover a wide space while still zooming in on fine details. Eufy claims its 4K resolution can capture a license plate from 30 feet away, and in practice, the micro lens does deliver striking detail. That means you can catch more than just the shape of a car or a blurry face; you’ll have a clear, usable image. The solar panel keeps the 9,400mAh battery topped up and can be mounted directly on the camera or up to 10 feet away, giving you flexibility for placement. Even in cloudy weather, users have reported the panel keeping the camera running without interruption. The unit is weather-resistant enough for year-round outdoor use, and the swiveling base supports 360-degree viewing with AI tracking to follow people or vehicles across the frame.
What do you think so far?
There are trade-offs, though. LTE mode offers true off-the-grid freedom, but live viewing is, reportedly, noticeably laggier than on wifi, and the included 100GB data allotment burns up fast. Switching the camera from LTE back to wifi can also take more effort than expected. Still, the flexibility is the real selling point: You can mount it at the edge of your property, along a long driveway, or anywhere a power outlet and router can’t reach.
