Solar WiFi or 4G Cameras: Which Line Should an Importer Stock?

The short answer: WiFi only works where a router already reaches. Everything else needs 4G

A solar WiFi camera runs on a battery charged by a solar panel, but it still pushes its video through a WiFi router that has to already exist on site. It solves the power problem, not the connectivity problem. So it only runs reliably when the mounting point sits inside the coverage of a live router: the corner of a yard, a boundary wall a few metres from the house, a small stockroom attached to the office. Step outside that radius — the middle of a coffee plantation, a site that was graded last week, a materials yard, a pump station, a shrimp pond, an open-air car park — and the WiFi simply does not reach. The only thing that works there is a 4G LTE solar camera: fit a SIM and it connects on its own, like a phone, independent of both the grid and any local network. That is why SolaGuard's 150-SKU catalogue is built around 4G — anywhere power and network cable have already been pulled usually has cameras already, and the part of the market nobody can serve yet is the part project buyers actually pay for.

For a distributor, the thing worth noticing is that buyers type "wifi" but usually mean "wireless". They are not asking for a connection standard, they are asking not to run cable. Sell the literal words of the question and you import a pallet that can only be mounted around houses; sell the need behind the question and you open up multi-site accounts.

The two options, judged as a business

Three hidden costs that eat the margin on a WiFi shipment

First, the repeater chain. To get WiFi out to the fence line, the customer bolts on range extenders, and every link you add is a new thing that can fail. When the picture stutters, nobody blames the extender — they bring the camera back to you.

Second, the return rate. The returned unit works perfectly on your bench, but you have already paid freight both ways, burned technician hours, and lost standing with your sub-dealers.

Third, the engineer's travel time. A 4G camera is live the moment it is mounted — real-world install time is 5–10 minutes per camera: fix the bracket, insert the SIM and memory card, scan the code to pair the app. An outdoor WiFi setup can mean repeat visits just to survey signal, and nobody reimburses you for that windscreen time.

AOV matters more than the WiFi-versus-4G question

The real technical line between cheap stock and stock you can put into a project is not the connection standard. It is how the camera decides when to record.

Most low-cost battery cameras only record when a PIR sensor detects body heat moving. That mechanism misses the three situations agricultural and industrial customers hit most often: slow movement (cattle drifting along a fence line), events outside the PIR's detection cone (someone lifting materials at the edge of the frame), and clips that start late, so the exact moment worth watching has already gone. When the customer opens the footage looking for evidence and finds nothing, the camera is useless — even though it is still "working normally".

AOV (Always-On Video) is the answer to that: continuous 24/7 recording at very low standby power, with AI scene analysis regulating the load. It is an industry-generic term, not any single brand's proprietary technology — worth knowing when you are reading quotations from several factories. For a seller, AOV is the easiest argument you will ever make: the customer does not need to follow the engineering, only that this camera has the whole recording and that one has a handful of disconnected fragments.

The 49 AOV models: which line for which market

Within the 150-SKU catalogue (wholesale prices quoted per order), 49 models are AOV, split across four series:

Three SKUs worth putting in the first sample order

• SG-C41G-10T66-V1, 2K (2.0MP), 8000mAh, 8W, IP66. The simplest way into a new market: an easy price to say yes to, and enough camera for fences, gates and yard entrances.
• SG-D42G-10F66-V1, 2K (2.0MP×2, dual lens), 8000mAh, 8W, IP66. The second lens buys you wide coverage and a close-up view at once — a clean argument against any single-lens camera in the same price band.
• SG-D42G-15F66-V1, 2K (2.0MP×2, dual lens), 20000mAh, 15W, IP66. For high-rainfall regions and long runs of overcast days, where the bigger battery and the 15W panel decide whether the camera survives the wet season at all.

Standard configuration across the catalogue is 1080p–2K, microSD up to 128GB, and IP66 weatherproofing on the outdoor models. 4K resolution, larger cards and different battery capacities exist only as custom/OEM builds — they are not stock items. Full specifications model by model are on the product catalogue page.

Import terms and margins

The factory is Shenzhen Leksell, established 2012, certified by TÜV Rheinland, with CE, FCC and RoHS as well. The Vietnam office is in Ho Chi Minh City — there is no warehouse in Hanoi or Bangkok, so plan northern distribution with that in mind.

OEM and private label apply to every model, the 49 AOV SKUs included: your logo, your packaging, your model names, and hardware customised to spec. Quantities, final pricing and lead times on a custom order are always confirmed by a person on the sales side — neither the website nor the chatbot can quote on their behalf. Volume tier pricing is on the wholesale page, and long-term partnership terms are on the dealer page.

What distributors ask before the first order

My customers are asking for the WiFi version. Ask them one question back: how far is the mounting point from the router, and does that router stay up when the power goes out? In most cases the answer rules WiFi out by itself. If your market genuinely needs a different configuration, the factory will build to spec from 100 units.

Is there a 4K model? Standard is 1080p–2K. 4K is a custom/OEM build only and is not part of the stock catalogue. This is where a lot of suppliers overstate, and it is also the first thing a buyer checks.

How much recording can it hold? It depends on resolution and how much the camera records, but the hardware ceiling is microSD up to 128GB in the standard configuration; higher-capacity cards are a custom order. Settle this number with your technical team before you commit to a project customer.
