No Power, No Wi-Fi: The Wholesale Buyer's Guide to Solar 4G Security Cameras

The short answer: the panel handles power, LTE handles the link

A solar 4G security camera runs with no mains power and no Wi-Fi because it solves those two dependencies separately. Power comes from an integrated photovoltaic panel that charges a lithium battery inside the unit. Connectivity comes from a 4G LTE modem with its own SIM. There is no electrical run to pull, no utility account at the site, and no router to install.

For a wholesale buyer in Latin America, Vietnam or the wider Southeast Asian market, the configuration that actually holds up in the field is an AOV (Always-On Video) model at 2K, with an 8W or 15W panel, a battery between 8000mAh and 20000mAh, local recording to microSD up to 128GB, and an IP66 housing. In SolaGuard's factory catalogue that is 49 AOV SKUs sitting inside a 150-SKU line, with wholesale prices quoted per order.

That is the short version. The rest of this article is what a buyer needs in order not to get the order wrong: why power and connectivity are sized differently, what separates AOV from a cheap PIR camera, and what to demand from the factory before the payment goes out.

"No power" and "no Wi-Fi" are two different problems

Plenty of catalogues sell them as one feature, and that is where the returns start. They are independent systems, and each one fails on its own terms.

Power: panel, battery and actual draw

The panel does not run the camera directly. It charges the battery, and the battery is what carries the unit through the night and through cloudy stretches. So the right question is not "how many watts is the panel?" but "is this panel sized for this camera's draw in this climate?"

An 8W panel with an 8000mAh battery is a balanced pairing for a single-lens unit in a region with reliable sun. Once the unit carries two lenses, records continuously, and sits in a region with a long rainy season, the pairing that sustains operation is a 15W panel with a 20000mAh battery. Specifying the small panel for a demanding unit is the number one source of "it shuts itself off in winter" complaints.

One detail worth passing to the installer and not only to the end customer: panel orientation and cleaning matter as much as panel size. A panel shaded three hours a day by one branch delivers a fraction of its rated output, and the customer reports it as a battery fault.

The link: LTE, SIM and coverage

A 4G camera does not depend on the customer's infrastructure, but it absolutely depends on carrier coverage at that exact spot on the property. Before closing a farm, ranch or construction project, check signal at the mounting point, not at the front gate.

Decide early who manages the SIMs. In wholesale distribution it pays to negotiate an M2M plan with a local carrier and sell it alongside the hardware: it is recurring margin, and it removes the single most common support call, which is the customer who ran out of data halfway through the month.

Local microSD recording up to 128GB is what holds the evidence. The 4G link is for live view, alerts, and pulling down the clips that matter. A properly configured system does not push continuous video over LTE — it pushes events. If a supplier proposes otherwise, the customer's data bill will kill the sale by month two.

AOV versus PIR: the difference that decides whether the customer reorders

AOV stands for Always-On Video: continuous 24/7 recording at low standby power, backed by AI scene analysis that decides when to escalate to an alert. It is a generic industry term, not a brand. The common alternative is the PIR-triggered camera, which wakes on a heat-and-motion sensor.

The PIR camera is cheaper and carries a structural flaw: it only exists when the sensor fires. Slow movement — someone walking tight against a wall, livestock drifting across a field, a vehicle rolling in with its lights off — often fails to trigger it, and anything happening outside the sensor's zone simply was never recorded. For a customer who bought the camera because of equipment theft on a jobsite or cattle rustling on a ranch, "there is no video of that moment" is total product failure, even if the unit performed exactly to its datasheet.

For the distributor this is a positioning decision. The budget line is for volume and an entry price point. The AOV line is what you defend in front of a corporate or government buyer who is going to demand continuous evidence.

The four AOV families and what each one is for

These are the 49 AOV references in the factory line, with their real ranges. The counts and prices are exact, because a buyer will check them against the product pages.

How that translates into an opening assortment:

• The AOV entry point: the SG-C41G-10T66-V1 is the single-lens unit for gatehouses, entrances and small storerooms. It is what you put in front of a customer comparing against a retail Wi-Fi camera.
• The workhorse: the SG-D42G-10F66-V1, dual lens at 2K, covers wide view and detail from the same pole. It is the reference that moves fastest on farm and construction projects.
• Hard climates and continuous duty: the SG-D42G-15F66-V1, with 20000mAh and a 15W panel, is what you specify where the rainy season is long or the customer will not tolerate an outage.
• Wide coverage without a second pole: the triple-lens series covers angles that would otherwise take two units and two installations.

How to qualify the factory before the order goes out

The hardware matters less than people think; the supplier matters more. These are the points worth confirming in writing rather than off a catalogue page.

Certification and track record. Shenzhen Leksell has been manufacturing since 2012 and is TÜV Rheinland certified, along with CE, FCC and RoHS. Ask for the certificates with numbers and validity dates. In several markets, customs clearance and LTE module type approval lean on those documents, and chasing them after the shipment leaves is expensive.

Honest specifications. A serious manufacturer tells you where its standard line ends. Here the standard is 1080p to 2K; 4K exists only as a custom or OEM development. Be wary of any datasheet promising the highest resolution, the biggest battery and the lowest price all at once — one of the three is false, and your end customer is the one who finds out.

Real lead times. Samples in 7 to 10 days by air. Volume production in 25 to 40 days by sea. Delivery inside Vietnam in 7 to 10 business days from the Ho Chi Minh City office. Plan your peak season against those numbers, not against a salesperson's optimism.

Installation. Each camera mounts in 5 to 10 minutes: pole or wall, orient the panel, insert the SIM and the microSD, pair the unit. That figure drives your customer's labour cost, and it is a selling point worth writing into the quote.

Margins, private label and the first order

The wholesale structure is straightforward: 20% margin from roughly 10 units, and 30% from roughly 50. The trial MOQ is 10 units, set deliberately so you can put hardware in the field in your own climate and on your own carrier before committing capital. For OEM and ODM work — your brand on the housing, the packaging and the app — the minimum is 100 units, and it applies across the whole line, including all 49 AOV models.

The practical advice for a distributor entering the category: order 10 units of two references, not 20 of one. You need to compare how an 8W/8000mAh unit behaves against a 15W/20000mAh unit in your own territory, because that comparison is what later lets you specify with confidence in front of a large account. Quantity, project pricing and delivery dates are always confirmed by a person, and the factory will build to specification when the project justifies it.
