Xiaomi has launched a solar-powered, 4G-connected security camera in China for places where standard Wi-Fi cameras are hard to install because there is no reliable electricity or internet.
The Smart Solar Camera 4 Pro 4G Dual-Camera Edition is aimed at remote monitoring for farmland, construction sites and other off-grid locations, according to Notebookcheck. The pitch is simple: combine solar charging, dual-SIM mobile data and two cameras in one outdoor device.
Remote-site owners get a camera built around missing power and missing broadband
The new Xiaomi camera is designed for users who need surveillance where a normal plugged-in camera or Wi-Fi-only model would be awkward. Notebookcheck cites farmland and construction sites as target environments. Related reporting from Gizmochina also points to orchards and other outdoor areas without access to Wi-Fi or outlets.
The device runs on a 9,900mAh battery and ships with a 7.6W solar panel. Xiaomi says the battery lasts more than a week on one charge, while the solar panel can keep it running indefinitely when sunlight is adequate.
Xiaomi’s central claim is that the camera can operate without manual charging as long as the solar panel gets enough sun.
That is the headline feature for builders, farmers and property owners managing sites that are expensive to wire. The practical question is: does the location get enough sunlight and mobile coverage to make the camera truly low-maintenance?
The camera connects through dual 4G SIM support rather than fixed broadband. Xiaomi says it can switch automatically between carriers to maintain a stable connection, with remote monitoring handled through the Xiaomi Home app.
For readers following Xiaomi’s broader device strategy, this launch sits near other hardware pushes covered by MLXIO, including the company’s battery-focused Xiaomi Power Bank 20000 22.5W and its connected home expansion with the €849 Xiaomi 75-Inch Mini-LED TV in Europe.
Buyers get dual 5 MP cameras, 3K recording and night monitoring
The Smart Solar Camera 4 Pro 4G Dual-Camera Edition uses two 5 MP sensors capable of 3K video recording. One camera is fixed for wide coverage. The other tracks moving subjects using AI.
Gizmochina reports that both cameras use f/1.6 lenses, with the tracking camera offering 355 degrees of horizontal and 95 degrees of vertical movement. That setup gives the product a split role: one lens watches the scene, while the other follows motion.
For unattended outdoor sites, that matters because a single fixed camera can miss detail when activity happens at the edge of the frame. The question for buyers is: does the AI tracking keep up with the movement that matters, or does it simply follow whatever crosses the scene?
Night coverage is another major part of the spec sheet. The camera supports color night vision using white lights and infrared illumination. Gizmochina says the system defaults to infrared night vision, then activates white LEDs to capture color footage when it detects a person in the dark.
The hardware is rated IP66 for dust and water resistance. That does not make it invincible, but it signals Xiaomi is targeting outdoor deployment in rain, dust and changing weather rather than sheltered indoor use.
Other features listed in the source material include:
- Two-way audio: Users can speak through the camera remotely.
- Motion-activated recording: The camera lowers recording intensity during quiet periods and resumes full-speed recording when activity appears.
- Local storage support: Gizmochina reports microSD support up to 256GB.
- Alerts and deterrence: Gizmochina says the camera can trigger a siren and flashing lights if it detects unusual activity.
Installers gain placement flexibility, but carrier and storage details still matter
Solar charging changes where this camera can be placed. If the panel receives enough sunlight and the 4G link holds, installers do not need to run power or depend on a nearby router.
That makes the product more flexible than a camera that requires either wired electricity or local Wi-Fi. It also narrows the job for installers: mount the camera, position the solar panel, confirm mobile reception and connect it to the Xiaomi Home app.
The question for installers is: what happens in weak-signal areas or long periods of poor sunlight?
The source material does not provide independent testing for battery endurance, solar charging speed in cloudy weather, carrier compatibility or long-term data use. Xiaomi’s more-than-a-week battery claim and indefinite solar operation claim remain vendor claims until tested in real outdoor deployments.
Storage behavior also deserves attention. Gizmochina says the camera uses an Always-On Video system that records a time-lapse at one frame every two seconds when the scene is quiet, cutting storage use by about 90%, then returns to normal recording when it detects a person or vehicle.
That is useful on paper because off-grid sites may not have fast upload capacity or constant app access. But buyers still need confirmed details on cloud storage, data-plan limits and how much video can be reviewed locally through the app.
Competitors now have a lower-priced Xiaomi option to answer in China
Xiaomi has priced the Smart Solar Camera 4 Pro 4G Dual-Camera Edition at 649 yuan, or about $96, in China. Notebookcheck names the eufy SoloCam S340 and Reolink Argus 3 Pro as comparable alternatives.
The comparison will likely center on whether Xiaomi can package enough autonomy into a cheaper off-grid camera. The table below shows the claims available from the supplied source material, without adding unverified specs for rivals.
| Product | Positioning from source material | Key comparison point |
|---|---|---|
| Xiaomi Smart Solar Camera 4 Pro 4G Dual-Camera Edition | Solar-powered 4G outdoor camera for off-grid sites | Dual 5 MP cameras, 3K recording, dual-SIM 4G, 9,900mAh battery |
| eufy SoloCam S340 | Named by Notebookcheck as a comparable alternative | Buyers may compare off-grid monitoring features |
| Reolink Argus 3 Pro | Named by Notebookcheck as a comparable alternative | Buyers may compare outdoor camera capabilities |
The question for competing brands is: can they match Xiaomi’s combination of solar power, dual-SIM connectivity and dual-camera coverage at a similar price?
Xiaomi has not confirmed an international launch. Notebookcheck says that, judging from past releases, the device may reach global markets in the third or fourth quarter of 2026 at a price 20 to 30% above domestic pricing. That remains an expectation, not an official launch plan.
For now, the watch item is narrow and practical: confirmed global availability, supported carriers, storage options, app features and warranty terms. Until Xiaomi answers those, the Smart Solar Camera 4 Pro 4G is best read as a China-first test of how far self-contained security hardware can move beyond the reach of outlets and routers.
Key Takeaways
- Xiaomi is targeting surveillance needs in places where power outlets and Wi-Fi are unavailable.
- Solar charging and dual 4G support could reduce maintenance for remote-site owners.
- The camera’s usefulness depends heavily on local sunlight and mobile network coverage.
