Solar Farm CCTV: A Sourcing Guide to Off-Grid 4G Cameras for PV Sites and Agriculture

The short answer

Solar farm CCTV is a camera that carries its own power supply — an integrated photovoltaic panel and battery — and sends video over a 4G LTE SIM instead of WiFi, so it can be mounted anywhere on a site with no grid connection, no trenching and no network cabling. In the SolaGuard catalogue that describes 49 AOV (Always-On Video) models, wholesale prices quoted per order, built around 8000mAh or 20000mAh batteries paired with 8W or 15W panels, recording at 1080p–2K to a microSD card of up to 128GB, rated IP66 for outdoor mounting, and installable in 5–10 minutes per unit with a pole bracket and a SIM. That is the whole category in one paragraph. Everything below is the detail a buyer needs before placing an order.

The search term itself is ambiguous in a way that matters commercially, and it pays to be explicit: it is used both by people securing a solar PV generation site against panel and copper theft, and by people securing an agricultural farm where the only practical power source is the sun. The hardware overlaps almost completely. The deployment logic does not.

Two different jobs behind one search term

Securing a solar PV site

A PV installation is a perfect target and a difficult one to guard. It is remote by design, spread over a large footprint, unmanned at night, and full of two commodities with immediate resale value: modules and copper cable. Fixed-line CCTV is a poor fit because running power and data to the perimeter of a large array costs more than the cameras, and because the site layout changes during construction phases.

The irony is that a PV site is surrounded by electricity it cannot easily share — inverter and combiner infrastructure is not a convenient tap point for a perimeter camera 400 metres away. A self-powered 4G camera sidesteps the whole problem. It mounts on an existing fence post or a dedicated pole, generates its own power, and reports over cellular. When the array is re-configured, the camera is unbolted and re-sited in minutes rather than re-cabled.

Securing an agricultural farm

On a working farm the assets are livestock, machinery, fuel, irrigation pumps and stored crop, and they are typically distributed across parcels a kilometre or more from the nearest building with power. This is the dominant use case across Vietnam and Latin America, where the buyer is usually trying to cover a gate, a pump house, a machinery shed and a stock pen — four locations that share nothing except an owner.

For distributors, this is the higher-volume of the two segments, because it repeats. A PV developer buys once for a site. A farm buys one camera for the gate, sees it work, and comes back for the other three positions.

Why AOV matters more on open sites than anywhere else

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 AI scene analysis to decide what deserves full-rate encoding, rather than sleeping until a passive infrared sensor wakes it up.

On a doorstep the distinction is academic. On a solar farm or a cattle paddock it decides whether the system works at all:

• PIR misses slow movement. A person walking a fence line at a deliberate pace, or crouching to cut cable, often fails to generate the rapid thermal differential a PIR sensor triggers on.
• PIR misses anything outside its cone. A wide field of view is useless if the trigger zone is a narrow wedge in front of the lens. Events at the edge of frame simply never get recorded.
• PIR gives you fragments, not a timeline. Post-incident, an insurer or a police report needs continuity — when the vehicle arrived, how long it stayed, which direction it left. A folder of three-second clips does not answer those questions.
• Ambient heat defeats it. In tropical daytime conditions the thermal contrast PIR depends on collapses.

This is why the 49 AOV models are the correct starting point for any quote involving open land, and why quoting a cheaper trigger-based unit into an agricultural tender usually produces a return, not a repeat order.

Choosing the right series

All four AOV series share the same core: 2K resolution, IP66 weatherproofing, 4G LTE, microSD storage up to 128GB, and OEM/private label availability.

The practical decision runs on two axes.

Power budget. The 20000mAh / 15W combination in the SG-D42G-15F66 series exists for sites where the panel will be shaded for part of the day, where the monsoon or rainy season brings long overcast runs, or where the camera will be worked hard by constant activity. On a clear, unshaded pole position with moderate traffic, the 8000mAh / 8W platform is the cost-efficient choice and is where most farm-gate volume sits. Getting this wrong is the single most common field failure — an under-powered camera on a shaded mount will brown out in the wet season and generate a warranty conversation that was avoidable at the quoting stage.

Coverage geometry. A single lens covers one approach. Dual lens covers a wide scene plus a detail view — the standard configuration for a gate, where you need both the vehicle and the plate. Triple lens, such as the SG-S43G-10T66-V* series, is for junctions and yards where three approaches meet and a single pole has to do the work of three cameras.

Common anchor models for a first quotation: SG-C41G-10T66-V1 as the entry position, SG-D42G-10F66-V1 for the standard gate, and SG-D42G-15F66-V1 for the high-autonomy build. The full catalogue runs to 150 SKUs, with wholesale prices quoted per order, including the non-AOV lines; the product range lists the specification of each variant individually.

Sourcing terms

The cameras are manufactured by Shenzhen Leksell, established 2012, certified by TÜV Rheinland and holding CE, FCC and RoHS.

Private label is available across the range, including all 49 AOV models — logo on housing and packaging, custom app branding, and specification changes such as higher resolution above the standard 1080p–2K, a larger battery and panel pairing, higher-capacity storage, or a different ingress rating, at OEM MOQ. Quantity pricing and lead time for a customised build always come from a person, not from a price list. Wholesale terms and the dealer programme cover the commercial detail; technical questions go to info@solaguard.net.

What to check before you commit a container

Three things separate a distributor who reorders from one who ends up with stock and a support problem.

Carrier compatibility. 4G band support is the one variable that does not travel. Confirm the bands against the networks in your market before bulk, not after — this is what samples are for, and why a 7–10 day air sample ahead of a 25–40 day sea shipment is cheap insurance.

Data plan economics. Continuous recording is local, to the microSD card; what crosses the network is live viewing and event upload. A buyer who does not understand this will size a SIM plan for a full-time stream and complain about cost. Sell the storage-plus-cellular model explicitly.

Mounting and orientation. The panel needs sun, and on a fence post someone will inevitably mount it facing the wrong way. The 5–10 minute installation figure assumes a competent pole position was chosen first. A one-page siting sheet in the local language, shipped in the box, prevents more returns than any specification upgrade.
