Solar Security Cameras Without Internet: How They Work and What to Verify Before You Import

They really do run without internet: 4G LTE, a solar panel and local recording

A solar security camera works without internet because it never depends on the site's internet in the first place. It replaces the three dependencies of a conventional camera with three of its own independent systems: power comes from a solar panel and a built-in battery instead of a mains connection; the link comes from a 4G LTE SIM instead of a WiFi router; and footage is written to a microSD card inside the housing instead of an NVR or a cloud server. In the SolaGuard catalogue, manufactured by Shenzhen Leksell (TÜV Rheinland certified, plus CE, FCC and RoHS, operating since 2012), that means 8W and 15W panels, batteries from 8000mAh to 20000mAh, microSD up to 128GB and an IP66 housing. Installation takes 5 to 10 minutes per camera: fix the bracket, insert the SIM, aim the panel, and the unit is online.

For a wholesale buyer, the real question behind the search is almost never whether the product exists. It is which of those three systems is the weak point of the supplier being evaluated. Here is what to check on each one before you commit to an order.

The three systems, one at a time

Power: the panel and the battery are specified together

The most common mistake when requesting a quote is to look only at battery capacity. What actually determines whether a camera survives a week of overcast highland weather or a rainy season is the relationship between panel output, battery capacity and the power draw of the recording mode. An 8000mAh unit with an 8W panel is built for sites with good sun exposure and stable scenes. A 20000mAh unit with a 15W panel is what you specify for latitudes with more cloudy days, for mounting positions under partial shade from trees or structures, or for sites where the operator wants continuous recording without rationing it.

The catalogue makes that split explicit: the 8W series ship with 8000mAh, the 15W series with 20000mAh. Nothing higher exists. If a supplier quotes you figures well above that range, ask for the cell datasheet and the unit weight — it is the fastest reality check available.

Connectivity: the SIM is the link, and the link carries an operating cost

The camera transmits over 4G LTE, which means every deployed unit consumes a data plan. For a distributor that is not a technical footnote, it is a line in the business model: whoever sells the camera usually ends up managing the SIMs as well, so decide early whether you resell a bundle with data included or let the end customer arrange their own plan.

Before closing a large order, confirm with the manufacturer that the module's bands match the bands the carriers actually use in your market. This is the single biggest cause of returns on imported 4G cameras: units that power up, show weak or intermittent signal and never hold a stable connection because the country's dominant band is not supported. It is a problem you solve at the sample stage, not at the container stage.

Storage: local first, cloud as an option

Recording lives on the microSD card — up to 128GB on stock models. That is precisely why the system keeps recording when cellular coverage drops: the live stream stops, the recording does not. Larger card support can be specified on custom orders, but plan your deployment around the figure the factory ships in series and treat any upgrade as a project variation with its own lead time.

AOV versus PIR: the difference you notice in the field

AOV stands for Always-On Video: continuous 24/7 recording at low standby power, using AI scene analysis to manage the draw. It is a generic industry term, not a brand. The classic alternative is the PIR-triggered camera, which wakes when an infrared sensor detects moving heat.

The weakness of PIR in real open-site applications is well known: it misses slow movement, it misses anything happening outside the sensor's zone, and it typically starts recording after the event has already begun. On a cattle ranch, in a yard or on a construction site, that produces clips confirming something happened without showing who or how. AOV keeps the video running and uses AI to decide when to raise quality and when to flag an event, so the review afterwards has a complete timeline.

For a distributor, AOV is also the argument that supports a premium over generic marketplace listings. Competing on price alone in this category is a race you lose.

The 49 AOV models in the catalogue

The full catalogue runs to 150 SKUs, with wholesale prices quoted per order. Of those, 49 are AOV models, organised into four series:

Three specific references make a representative first sample (wholesale prices quoted per order): the SG-C41G-10T66-V1 as the single-lens entry point; the SG-D42G-10F66-V1 as the typical dual-lens volume seller; and the SG-D42G-15F66-V1 where the project demands the 20000mAh battery and the 15W panel. Standard resolution across the line is 1080p to 2K; 4K exists only as a custom OEM development, never as stock. The full catalogue is at /en/products/.

Import terms: MOQ, margins and lead times

MOQ is 10 units for a trial order and 100 units for OEM/ODM projects. Distributor margins run at 20% from around 10 units and 30% from around 50. Private label is available on every model, including all 49 AOV units.

The lead times to build into your planning:

The factory is in Shenzhen and the regional office is in Ho Chi Minh City. We do not operate warehouses in other cities, so any promise of immediate delivery from a third location should be confirmed in writing before you commit to your own customer.

What to test at the sample stage

A 10-unit trial order, used properly, saves you from a badly bought container. Verify these in your own market rather than on paper: registration on local carrier bands with a real SIM; battery behaviour after several consecutive days without full sun; reading the microSD card on a device other than the one that recorded it; and a timed installation performed by someone other than you, to confirm that the technician who will deploy at volume genuinely completes it in the 5 to 10 minute range.

How an OEM project comes together

The catalogue is what ships from stock; the factory builds to specification. Higher resolution, a larger battery and panel, expanded storage capacity, custom packaging and private label are all routine variations on the existing lines. The one thing that never comes off a web page is the quotation: quantity, price and lead time on an OEM project are settled with a person, because they depend on the exact scope of the modification and on the quarter's production calendar.

If you are evaluating volume, the full commercial terms are at /en/wholesale/ and the territory and support framework for distributors is at /en/dealer/. For specific technical specifications or a shortlist built around your application, email info@solaguard.net with your estimated unit count and destination country — with those two figures, the reply comes back with real pricing and real lead times instead of a generic range.
