4G LTE Remote-Monitored Security Cameras for Construction Sites: A Wholesale Buyer's Spec Guide

The short answer

A 4G LTE remote-monitored security camera for a construction site is a camera that carries its own SIM card, uploads video over the mobile network instead of site WiFi, and runs on an internal battery recharged by an integrated solar panel — so it works on day one of a project, before the temporary power board is even energised. The configuration that actually ships in volume today is 1080p–2K resolution, an 8000mAh–20000mAh battery paired with an 8W or 15W solar panel, local microSD storage up to 128GB, and an IP66 housing rated for rain, dust and site debris. SolaGuard covers this segment with 49 Always-On Video (AOV) SKUs inside a 150-SKU catalogue, with wholesale prices quoted per order, manufactured by Shenzhen Leksell — established 2012, TÜV Rheinland certified, with CE, FCC and RoHS. Each unit installs in 5–10 minutes with no trenching, no cable run and no electrician.

That is the specification. The rest of this article is why construction sites in particular punish the wrong choice, and what a distributor or importer should check before committing to a container.

Why construction sites break ordinary battery cameras

Construction is the hardest environment a battery camera faces, for reasons that have nothing to do with image quality.

There is no power and no network, by definition. A site under construction is an unpowered plot with a fence around it. Mains arrives late; permanent broadband arrives later still, often after handover. Any camera that assumes a socket or a router is a camera that protects the building only after there is nothing left to steal. LTE plus solar removes both dependencies.

The site moves. A tower crane base, a materials laydown yard and a finishing compound are three different perimeters over the life of one project. Cameras get relocated repeatedly — sometimes weekly. A 5–10 minute install is not a marketing line in this vertical; it is the difference between a site manager who moves cameras as the work moves and one who leaves them pointed at a finished corner because relocation is a half-day job.

The threats are slow and quiet. Material theft is not a sprint across a lawn. It is a truck reversing to a rebar stack at 02:40, two people loading for twelve minutes, and a slow drive-out. Copper, cable drums, fuel, power tools and formwork walk off the same way. Diesel siphoning barely involves movement at all.

That last point is why recording mode matters more than megapixels.

AOV versus PIR-triggered recording

AOV — Always-On Video — is an industry-generic term, not a SolaGuard trademark. It describes a camera that records continuously at low standby power, using on-device AI scene analysis to decide what to encode at full quality rather than deciding whether to wake up at all.

The alternative, PIR triggering, keeps the sensor asleep until passive infrared detects a heat differential. It is cheap and it preserves battery, and on a construction site it fails in specific, predictable ways:

For a Vietnamese or Latin American distributor, the second-to-last row is the commercially important one. In Ho Chi Minh City, Guayaquil or Monterrey, midday surface temperatures narrow the gap between a human body and the background that PIR depends on. A camera that performs adequately in a temperate demo fails in the field, and the return comes back to you, not to the factory that sold it.

The four AOV series, exactly as catalogued

All four series are 2K, IP66, and available for OEM and private label. Nothing here is a roadmap item.

How to match series to site

Perimeter and fence line — SG-C41G-10T66-V1. Single lens, 8000mAh, 8W. The volume unit for gate approaches, fence runs and container doors, where one well-aimed field of view does the job and unit cost decides the order size.

Wide coverage on one mast — SG-D42G-10F66-V1. Dual lens on an 8000mAh/8W platform, for corners and yard openings where a single lens forces a compromise between overview and detail.

Winter, monsoon and shaded placements — SG-D42G-15F66-V1. The 20000mAh battery and 15W panel are what you specify when the camera sits under scaffold netting, faces away from the sun, or has to ride out a week of overcast weather with no maintenance visit. On sites where nobody wants to climb back up the mast, this is the safe specification.

High-value zones — the SG-S43G-10T66-V series.* Triple lens on the 8000mAh/8W platform, for fuel bowsers, tool stores and plant compounds that justify more coverage from a single mounting point.

Full specifications for every variant are on the product catalogue.

Storage, data and what your customer will ask on the call

Every AOV unit records locally to microSD up to 128GB. For a construction deployment, treat the card as the evidence archive and the LTE link as the review and alert channel — not the other way round. Continuous cloud upload of every camera on a site is an operating cost that recurs monthly and lands on your customer's desk, not yours, and they will remember which distributor set that expectation. The pattern that survives contact with a real project: continuous local recording, AI-filtered events and clips pushed over LTE, and the card pulled or reviewed when an incident needs the full timeline. If a client needs more retention than a 128GB card holds at their chosen bitrate, that is a conversation about recording schedules and card rotation, or a custom build — not a spec you should promise from a datasheet.

On connectivity, confirm the LTE bands against the carrier your customer will actually use before you quote. This is the single most common cause of a returned unit in cross-border camera sales, and it is entirely avoidable at the sample stage.

Sourcing terms for importers and distributors

The commercial terms are as fixed as the specifications:

• MOQ — 10 units for a trial order, 100 units for OEM/ODM.
• Dealer margin — 20% from approximately 10 units, 30% from approximately 50.
• Lead times — samples 7–10 days by air; bulk production 25–40 days by sea; 7–10 business days within Vietnam from the Ho Chi Minh City office.
• OEM and private label — available on every model, including all 49 AOV SKUs. Logo, packaging and app branding.
• Certification — TÜV Rheinland, CE, FCC, RoHS, from a manufacturer operating since 2012.

A realistic first move for a distributor entering the construction segment: take a 10-unit trial across two series — the entry single-lens unit and one 20000mAh/15W dual-lens unit — and put them on a live site through a full weather cycle. The 15W platform justifies its price difference in exactly the conditions a showroom cannot reproduce, and a site manager who has watched both perform will specify for you on the next project.

For 4K, higher-capacity power systems, larger storage or non-catalogue housings, the factory builds to specification at OEM volumes — quantity, pricing and lead time come from a person, not a page. Pricing tiers and container terms are on the wholesale page, and territory arrangements through the dealer programme or info@solaguard.net.
