TL;DR

On a solar 4G camera the panel runs the camera and the battery covers the gap. A sourcing guide to the 8000mAh/8W and 20000mAh/15W platforms behind SolaGuard's 49 AOV models.

The short answer: the panel runs the camera, the battery covers the gap

On a solar-powered 4G security camera, battery life is not the number that decides whether the camera stays online — the solar panel is. The battery is a buffer that carries the unit through the hours and days when the panel harvests nothing: overnight, a week of monsoon cloud, a dust-filmed glass surface, a pole aimed at the wrong part of the sky. Across SolaGuard's 49 AOV (Always-On Video) models there are exactly two power platforms: 8000mAh paired with an 8W panel, and 20000mAh paired with a 15W panel. That is the entire range; nothing larger is built. So the question that matters in procurement is not "how many days does it run on a charge," but "in your customer's worst month of weather, does the panel put back what a day of continuous recording takes out?"

Why "standby time" on a datasheet is the wrong number to compare

Most battery-camera spec sheets quote standby endurance — camera asleep, PIR sensor armed, radio idle, waiting for a heat signature. That figure is real and almost useless for AOV. AOV keeps the encoder running around the clock and uses AI scene analysis to hold standby draw down, rather than sleeping until something crosses a detection zone. That is precisely why it catches slow movement, a vehicle drifting past outside the PIR arc, and events at the edge of frame that a triggered camera never wakes for. It also means the duty cycle is effectively continuous, so a standby figure describes a mode the camera is never in. When two suppliers quote wildly different endurance for similar capacity, they are usually quoting different duty cycles — not different engineering.

AOV, worth saying plainly, is an industry-generic capability, not a SolaGuard trademark. Any serious supplier should be able to tell you how their AOV implementation manages power. If they answer with a standby number, they haven't.

What actually drains the battery in the field

Draw Why it matters Who controls it
4G transmit power A camera at the cell edge burns far more radio power than one with strong signal, and it does it continuously Site survey, antenna placement, carrier and band choice
Continuous encode + AI scene analysis The always-on baseline that defines AOV Fixed by the operating mode
Night IR and spotlight Every dark hour adds illumination load on top of the baseline Scene design, ambient lighting, how wide the scene is
Remote live view Every app session is a live cellular upload on demand — the most underestimated drain of all End-user behaviour, not the hardware
Ambient temperature Cold slows charge acceptance; sustained heat is hard on cells Climate and mounting (avoid metal surfaces in full sun)
Panel yield loss Dirt, partial shade, wrong tilt, wrong azimuth, rainy season The installer — and this is where most failures originate

The pattern we see in returns and support escalations is consistent: the complaint arrives as "the battery is weak," and the cause is an installation that starves the panel. A branch that shades the panel for two hours a day, a pole aimed to suit the camera's field of view with no thought for where the sun is, or a dusty site where nobody ever wipes the glass. None of that is fixed by a bigger cell. All of it is fixed at install time, for free.

The second pattern is the customer who checks the live feed twenty times a day. That behaviour turns a comfortably-sized system into a marginal one, and it is worth telling your dealers so they can set expectations before the first support call.

The two power platforms, and the SKUs on each

Series Variants Battery Panel Imaging Rating
SG-C41G-10T66-V* 4 8000mAh 8W 2K (2.0MP) IP66
SG-D42G-10F66-V* 18 8000mAh 8W 2K (2.0MP×2, dual lens) IP66
SG-S43G-10T66-V* 11 8000mAh 8W 2K (2.0MP×3, triple lens) IP66
SG-D42G-15F66-V* 16 20000mAh 15W 2K (2.0MP×2, dual lens) IP66

That is 49 AOV SKUs inside a 150-SKU catalogue. Reference points buyers usually quote back to us: SG-C41G-10T66-V1, SG-D42G-10F66-V1, and SG-D42G-15F66-V1, with wholesale prices quoted per order. The full spec sheets are on the product catalogue.

Note what the table does and does not say. The 20000mAh platform carries 2.5× the reserve of the 8000mAh platform, and its 15W panel harvests close to double what the 8W panel does. Both sides scale together, and that is the design intent — a large battery behind a small panel simply takes longer to refill and rides into the next cloudy stretch half full. Capacity alone is not a spec; capacity paired with harvest is.

Also note that multi-lens models are feeding more than one sensor on the same 8000mAh/8W platform. They are not fragile, but they leave less headroom for a poor mounting position than a single-sensor unit does, which makes install discipline more important on the triple-lens series than on the entry models.

Matching the platform to the deployment

The 8000mAh / 8W platform fits when

  • The site is open — farmland, a fenced yard, a rooftop, a parking area — with unobstructed sky through the middle of the day.
  • The dry season is long and the cloudy stretch is measured in days, not weeks.
  • Viewing is mostly retrospective: the end user pulls clips after an incident rather than watching live.
  • Price per point matters more than margin for error, as it usually does on multi-camera rollouts across a large property.

Move to the 20000mAh / 15W platform when

  • The site sees a genuine rainy season — the Mekong Delta and Central Highlands through the wet months, the Amazon basin, Andean valleys with persistent morning cloud, the Central American rainy season.
  • The panel cannot be placed ideally: canopy shade, a north-facing wall, a compromise angle forced by the mounting point.
  • Signal is weak. A camera transmitting at the cell edge, continuously, is the single largest variable load in the system.
  • The end user is an active watcher — a site manager checking the feed all day, or a security operator using the cameras as a patrol substitute.
  • Downtime is expensive. Livestock, construction plant, fuel and equipment stores don't forgive a camera that went dark for the three days that mattered.

The sizing rule worth passing to your sales team is simple: spec for the cloudiest fortnight of the year, not the annual average. Annual averages sell the cheap SKU and generate the warranty claim.

What to verify before you commit to a container

Sample against your worst site, not your easiest. Trial MOQ is 10 units, samples ship 7–10 days by air. Put at least one on the shaded pole, one at the weak-signal corner, and leave them through a wet stretch. A camera that survives your worst site will survive the rest of the order.

Storage. microSD up to 128GB is standard; larger cards are a custom-order conversation. Continuous AOV recording cycles a card considerably faster than event-clip recording does, so specify endurance-rated cards for your customers and confirm loop-overwrite behaviour during the sample stage. This is the spec distributors most often discover after the first support wave.

Ingress protection. IP66 on outdoor models — tested and certified, and we will not quote a higher figure than the enclosure holds. If a competing datasheet claims a better rating at the same price point, ask which lab issued it and on which sample.

Certification and provenance. Manufactured by Shenzhen Leksell, established 2012, TÜV Rheinland certified, with CE, FCC and RoHS. For customs clearance in Vietnam and across Latin America, those documents move faster than any spec argument.

Installation. 5–10 minutes per camera, no grid power and no WiFi. The time saved is real, but spend part of it aiming the panel. On solar, ten seconds of thought about azimuth is worth more than any upgrade on the order form.

Order mechanics for distributors

Trial MOQ is 10 units; OEM and ODM start at 100. Dealer margin is 20% from around 10 units and 30% from around 50 — the tier structure is set out on the dealer programme page. Lead times are 7–10 days by air for samples, 25–40 days by sea for bulk, and 7–10 business days for Vietnam, served from our Ho Chi Minh City office.

Private label is available across the range, including all 49 AOV models, with the usual scope of housing marks, packaging, app branding and firmware defaults — details on the wholesale page. Where buyers most often use customisation on this topic is exactly the one covered above: a battery and panel combination sized for their own market's rainy season rather than ours. Higher resolution, larger battery and panel, and more storage are all buildable to specification, but quantity, pricing and lead time for a custom build always come from a person, not from a web page. Email info@solaguard.net with your site conditions — latitude, season, signal, viewing habits — and you will get a platform recommendation instead of a catalogue dump.
