Solar Construction Camera: The Wholesale Buyer's Specification Guide

What a solar construction camera is, and the specification that actually ships

A solar construction camera is a self-powered 4G LTE security camera — solar panel, rechargeable battery, cellular modem and AI recording in one weatherproof housing — made to be bolted to a pole, fence line, container or scaffold tower on a site that has no mains power and no fixed internet. For a wholesale buyer, the honest working specification that ships in volume today is: 1080p–2K resolution, an 8000mAh–20000mAh battery matched to an 8W or 15W panel, microSD storage up to 128GB, an IP66 housing, AOV continuous recording, and a 5–10 minute install per camera. SolaGuard's catalogue runs 150 SKUs, with wholesale prices quoted per order, of which 49 AOV models are built for exactly this duty. If a competing quote sits far outside those brackets, ask to see the cell and panel datasheets before you commit to a container — inflated battery and storage figures are the most common way a construction-grade camera is oversold.

The rest of this guide covers why building sites destroy ordinary cameras, how the four AOV series map to real site conditions, and the commercial terms an importer in Vietnam or Latin America should settle before the trial order.

Why a construction site is its own product category

Retail solar cameras are designed for a house: one fixed wall, a known WiFi router, an owner who charges the unit if it dies. A construction site gives you none of that, and the difference shows up in the return rate.

The site has no power, no WiFi, and no stable layout

On day one there is a fence and a gate. By month three there is a structure blocking the line of sight the camera was installed for, a crane where the compound used to be, and a materials yard that moved twice. A construction camera has to be re-sited repeatedly by a foreman, not an installer — which is why the 5–10 minute install per camera matters more here than anywhere else. Mounting brackets that need a laptop, a configuration cable or a rooftop cable run get abandoned on the second move.

Cellular connectivity is not a convenience feature on these sites, it is the only option. There is no broadband drop to a plot of land, and site WiFi — where it exists at all — is a temporary router in the office container that goes off with the generator at night, precisely when you need the footage.

Dust, vibration and water get in through the seams

Concrete dust, cutting slurry, diesel exhaust and the vibration of plant machinery are harder on a housing than ordinary outdoor weather. IP66 — dust-tight, protected against powerful water jets — is the rating to hold suppliers to for outdoor construction use, and it is the rating on every SolaGuard AOV model. A higher ingress rating exists on the scale and is worth asking about for submersion risk, but for a pole-mounted site camera the failure mode is rarely standing water; it is a cheap gasket on the microSD door and a panel surface nobody has cleaned since the pour.

Theft is the actual threat model

Copper, cable drums, fuel, compressors, formwork and generators go missing between shifts. That means the camera has to record at the moment someone walks a bundle of rebar to a gate at 3 a.m. — and to keep working after the first incident, which is why mounting height, physical security of the unit and the presence of a second lens matter as much as megapixels.

AOV versus PIR: the difference between footage and an empty card

AOV — Always-On Video — is an industry-generic term, not a brand. It means the camera records 24/7 at low standby power, using AI scene analysis to decide what to keep at full quality instead of waking from sleep on a passive infrared trip.

The distinction is commercially important because PIR-triggered solar cameras fail in ways a buyer only discovers after deployment. PIR misses slow movement, it misses anything outside the sensor's zone even when it is clearly in the frame, and it drops the first seconds of an event while the camera wakes and starts encoding. On a construction site, the theft you care about is someone moving deliberately and quietly through a corner of the yard — the exact profile a motion trigger is worst at. With AOV the recording is already running, so the approach, the act and the exit are all on the card.

When you demo a sample to a contractor, this is the demonstration that closes the sale: walk slowly across the far edge of the frame and play back both cameras.

The four AOV series, and how to match them to a site

All 49 AOV models are 2K and IP66. What varies is the lens configuration and the power budget, and those two choices are what a distributor actually has to stock against.

Where the 8W / 8000mAh platform is the right answer

The 8W panel and 8000mAh battery cover the majority of site positions: an open compound, a gate, a materials yard, a perimeter run with clear sky. The single-lens SG-C41G-10T66-V1 is the volume entry point for perimeter coverage where you need many units rather than a few clever ones, and the dual-lens SG-D42G-10F66-V1 adds a second view — typically a wide overview plus a closer field — from one mount and one SIM.

The triple-lens SG-S43G-10T66 series, 11 variants, is the choice for corners and gate houses where one pole has to cover several directions that would otherwise need two or three separate installs, each with its own data plan.

Where to step up to 15W / 20000mAh

The SG-D42G-15F66 series pairs the 20000mAh battery with the 15W panel, and it exists for positions the smaller platform struggles with: a pole in partial shade from a structure or a tower crane, a north-facing wall in the northern hemisphere, a rainy season with long overcast runs, or a camera that is being asked to hold its recording and uplink duty at a busy gate. SG-D42G-15F66-V1 is the representative unit. Note how much the 16 variants differ — this series is where the optional features live, so specify the variant, not just the series, on your purchase order.

Full specifications and the rest of the 150-SKU range are on the product catalogue.

A practical stocking rule

Distributors who carry both platforms sell more than those who carry one. Quote the 8W platform as the standard site camera and hold the 15W as the shaded-position and rainy-season upgrade — it gives your sales team a reason to return to a customer after the first deployment instead of discounting the same SKU.

Storage, retention and what to tell the end customer

Every AOV model takes a microSD card up to 128GB. That is the ceiling, and it is the single figure most often exaggerated in this category, so it is worth being straight with your customers about how it behaves: the card runs as a rolling buffer that overwrites the oldest footage. Retention depends on how many lenses are recording and how the quality is configured, so the useful question for a contractor is not "how many days" in the abstract but "how quickly can someone get the clip off the card after an incident."

In practice that means three things in your pre-sales conversation. Cards should be supplied and pre-installed with the camera, not left to the customer to buy locally, because the failure you will be blamed for is a counterfeit card. Anything the customer must keep long term — an incident file for an insurer or the police — should be pulled to a phone or laptop within days, not weeks. And where a client wants genuinely long archives across a multi-year project, that is a cloud or on-site recorder conversation layered on top of the cameras, not something a card can solve.

Commercial terms to settle before the trial order

Manufacturing is by Shenzhen Leksell, established 2012 and certified by TÜV Rheinland, with CE, FCC and RoHS. For an importer, those certificates matter at customs and in tenders — public works and larger contractors increasingly ask for them by name — so request the certificate copies during sampling rather than after you have a container in transit.

The 10-unit trial exists so you can put cameras on a real site before committing capital. Use it properly: place them in the worst positions you have — the shaded pole, the dusty corner, the gate that gets moved — because that is what tells you which platform to stock, and it is the deployment your first contractor customer will ask to see.

OEM and private label

Private labelling is available across the catalogue, including all 49 AOV models, from 100 units. For a distributor selling to contractors, branding the hardware is what turns a resale into a product line: the site manager who photographs your camera on a pole is photographing your name, not a generic import. Custom work beyond branding — higher resolution than the 1080p–2K standard, a different battery and panel pairing, more storage — is built to specification rather than picked from stock, so quantity, pricing and lead time on those come from a conversation, never from a web page. Current wholesale pricing tiers and the dealer programme cover the standard terms.

Five questions that separate a factory from a trading company

Use these on every supplier you shortlist, including this one.

• Give me the exact battery capacity and panel wattage per SKU, not a series average. A supplier who cannot produce a per-model table is reselling someone else's stock.
• Which certificates are held, by which body, and can I have the copies now? Certification claims are cheap; certificate numbers are not.
• Is recording AOV or PIR-triggered, and can I test both on a sample? The answer changes what the camera is worth on a theft-driven site.
• What is the real lead time, air and sea, at my quantity? Compare it against samples in 7–10 days and bulk in 25–40 days — a supplier quoting dramatically faster bulk production is quoting from stock they may not hold.
• Who supports the end customer when a unit fails in month four? Regional presence matters. SolaGuard's regional office is in Ho Chi Minh City; ask any supplier to name theirs rather than describe a network.

A solar construction camera is not a complicated product, but it is an easy one to specify badly. Hold the numbers — 8000mAh to 20000mAh, 8W or 15W, 128GB, IP66, 1080p–2K — and the rest of the decision is commercial: which platform you stock, what margin the volume gives you, and whether your name goes on the housing.
