Solar-Powered Construction Security Camera Systems: A Sourcing Spec for Wholesale Buyers

What a solar-powered construction security camera system actually is

A solar-powered construction security camera system is a self-contained unit — camera, 4G LTE modem with its own SIM, lithium battery, solar panel and local microSD storage — mounted on a pole, fence, container or scaffold at a site with no mains power and no fixed internet. In SolaGuard's catalogue that means an IP66 housing, 1080p–2K video, a battery between 8000mAh and 20000mAh, an 8W or 15W panel, microSD up to 128GB, and 5–10 minutes of installation per camera with no trenching, no electrician and no site network. Across the 150-SKU catalogue, wholesale prices are quoted per order; the 49 AOV (Always-On Video) models are the group that actually suits an active construction site.

Everything below is about specifying and sourcing that system at volume: which variant fits which site, what the factory terms are, and what to check before you sign off on a quote.

The four components, and the one buyers misjudge

Camera and lens count

Resolution is 1080p–2K as standard across the range, with 4K available only as a custom or OEM build. On construction sites the more useful variable is lens count rather than pixels. A single-lens unit covers one approach — a gate, a fuel store, a generator. A dual-lens unit gives you a wide scene plus a detail view from one mounting point, which matters when you have fewer poles than angles. A triple-lens unit covers a compound or a corner where three directions meet and you would otherwise be paying for three separate installs, three SIMs and three sets of mounting labour.

4G LTE, not Wi-Fi

A half-built structure has no router, and site Wi-Fi tends to arrive with the site office — months after the material theft window opens. Every unit here carries its own LTE connection, so the camera goes live the day the hoarding goes up and moves with the work as the site changes shape. Budget one data plan per camera when you build a customer quote; distributors who forget this line item find it eating their margin later.

Battery and solar panel — the pairing that decides uptime

This is the component buyers most often get wrong, because it is the one that fails quietly. The catalogue offers two pairings: 8000mAh with an 8W panel, and 20000mAh with a 15W panel. The smaller pairing is correct for an unobstructed south-facing mount with good year-round sun. The larger one is for sites where the panel will be shaded part of the day by a crane, a tower block or the structure being built, for short winter days, and for high-traffic scenes where the camera is analysing and recording continuously rather than sitting idle. Specifying 8000mAh into a shaded winter site produces a camera that browns out at 5 a.m. — precisely when a site gets robbed.

Storage

microSD up to 128GB is standard, with higher-capacity cards available on custom orders. Local recording is what keeps footage alive when the LTE signal drops behind a concrete core; cloud is for the clips a supervisor needs to pull remotely. Sell both, and make the retention expectation explicit in writing — how many days a card holds depends on resolution, scene activity and bitrate settings, and a customer who assumes "a month" will treat any shorter figure as a defect.

Why PIR-triggered cameras fail on construction sites

Most cheap solar cameras record only when a passive infrared sensor detects heat crossing a defined zone. That model breaks down on a construction site in three predictable ways: a person moving slowly, deliberately, at the edge of the zone may never trigger it; a flatbed reversing up to the fence line stays outside the zone while material is lifted over it; and the incident you need to prove often begins ten seconds before the trigger, in footage a PIR camera never recorded.

AOV — Always-On Video — is the industry-generic answer, not a SolaGuard trademark. The camera records continuously and uses AI scene analysis to hold standby power low enough that a solar panel can sustain it, instead of waking from sleep on a heat event. For evidence that will be handed to an insurer, a main contractor or the police, continuous footage with context around the incident is a materially different product from a folder of two-second clips. It is also the single easiest thing to demonstrate in a sales meeting: play a PIR clip and an AOV clip of the same event side by side.

The 49 AOV SKUs, by series

A workable mapping for a mid-size site: single-lens SG-C41G-10T66-V1 on straightforward perimeter approaches with clear sun; dual-lens SG-D42G-10F66-V1 at the main gate and the material compound; and SG-D42G-15F66-V1, on the 20000mAh/15W pairing, wherever the mount is shaded, the scene is busy, or the camera has to survive a run of overcast days. The full range, including the non-AOV models that suit yards and depots with easier lighting conditions, is on the product catalogue.

Sourcing terms

The manufacturer is Shenzhen Leksell, established 2012, TÜV Rheinland certified, with CE, FCC and RoHS on the range — the certification set your customs broker and your commercial customers will ask for, so request the certificates with the quotation rather than after the PO.

OEM and private label are available on every model, including all 49 AOV SKUs, from 100 units. For a distributor building a construction-security line under their own brand, that threshold is low enough to test a market before committing to a container. The Vietnam office is in Ho Chi Minh City; terms, tier pricing and the OEM process are set out on the wholesale page and the dealer programme, and quantity-specific pricing and lead times always come from a person, never from a page.

Questions to put to any factory before you commit

Use these on us and on everyone else you are quoting:

• Is the ingress rating consistent across the range, or only on the flagship? Ask for it per SKU. Every model listed above is IP66.
• Which battery and panel pairing ships with the SKU you quoted? Series with mixed configurations are common; confirm the exact variant, not the series.
• Is the recording genuinely continuous, or motion-triggered with a short pre-roll? Ask for a raw file, not a highlight reel.
• What is the maximum supported card capacity, and is a card included? Assume it is not unless stated.
• What is the actual install time and does it need a technician? These mount and provision in 5–10 minutes per camera; anything requiring cabling changes your customer's labour cost per site.
• Can the same SKU be built to a higher specification later? Higher resolution, larger battery and panel, more storage and your own branding are all buildable to order — but they are custom-order terms with their own lead time, not catalogue stock.

Get those six answered in writing and the quote in front of you becomes comparable to the next one. Questions on a specific site layout or a mixed container: info@solaguard.net.
