When you think about a security camera, Wi-Fi is usually part of the equation, unless your intended location is somewhere remote, like a barn, a construction site, or some other location where there is no Wi-Fi and no practical way to get it there.

To fix that problem, SEHMUA developed its 4G LTE cellular solar security camera (model number RBX-S40). It combines cellular connectivity, solar power, a battery, and a completely wireless installation in a relatively inexpensive surveillance package (around $40).

This latest camera is not intended to replace a sophisticated commercial video-surveillance system, but for remote monitoring, it addresses several of the problems that make conventional cameras impractical. Simply position it somewhere within cellular coverage, install the solar panel where it can receive sunlight, and you’re all set. I got it all together in under an hour.

The camera is battery-powered, with the solar panel providing the means to keep the battery charged. Obviously, solar performance depends on weather, panel orientation, seasonal sunlight, and how frequently the camera is operating. The solar panel is separate from the camera; hence, it can be positioned for better exposure to the sun.

Storing Your Videos

Storage is another area where the Sehmua camera takes a sensible approach. It supports both local and cloud storage. A user can install a TF card with a capacity of up to 128 Gbytes and keep recorded video locally. That is useful when a reliable cellular connection is available for alerts and remote viewing but uploading every video stream to the cloud isn't desirable. The cost of Cloud storage can be less than $20 annually, which is far lower than many competitive Cloud-connected security systems.

A Viable App

The UBox app that accompanies the camera simplifies the setup process. It’s also very straightforward for day-to-day camera operation. Viewing the camera remotely, accessing stored video, and managing the device are handled through the same interface. That's important because the hardware is only half of a remote-monitoring system. If the software is difficult to use, the system isn't particularly useful.

There are, of course, limitations. Cellular coverage is mandatory, and the camera's performance is tied to the available 4G LTE service. It also isn't a high-end machine-vision system. If your application requires that, you may want to look elsewhere. But if cost is at or near the top of your priority list, definitely check out the SEHMUA security camera.
