AOV Camera: What "Always-On Video" Means and How It Differs From PIR

AOV stands for Always-On Video

AOV is short for Always-On Video. It describes a camera that records continuously, 24 hours a day, instead of waking up only when a PIR sensor picks up a moving heat signature. The question turns up in English, Spanish and French searches for the same reason: the acronym gets printed on datasheets untranslated and unexplained, and almost no seller says what it means in practice. One thing worth settling up front: AOV is a generic industry term, not a trademark or a technology owned by any single manufacturer.

What makes that mode possible on a battery-powered solar camera is AI scene analysis. The camera holds its image sensor in a permanent low-power watching state and only escalates to full-quality recording — with an event marker and a phone notification — when the AI recognises something that matters: a person, a vehicle, an animal. You get the whole day as one timeline without the power draw of uninterrupted maximum-quality recording. For the detail on how that power budget is managed, we work through it in the AOV solar camera and 24/7 recording guide.

Why the PIR difference is not a marketing detail

A PIR (passive infrared) sensor does not see. It measures moving thermal contrast inside a detection cone. That works well when someone crosses sideways, close by and at speed. It falls down in the situations that are most common in the field:

• Slow or head-on movement. Someone walking slowly straight towards the camera produces very little lateral heat change. The PIR may never trip at all.
• Events outside the zone. Whatever happens right at the edge of the cone — a gate, the corner of a warehouse, the boundary of a plot — simply does not exist for the sensor.
• High ambient heat. At midday, with ground and walls at elevated temperature, the thermal contrast of a body shrinks and detection loses sensitivity. In hot climates that is not an edge case, it is the norm.
• The second lost to waking up. Even when the PIR does trip, the recording start-up eats the moment just before: the plate on the way in, the face before the head turns away.

The difference shows up on the day something goes wrong. With PIR you open a folder of clips and try to reconstruct what happened between one and the next. With AOV you rewind the tape.

What hardware actually sustains AOV mode

This is the point at which datasheets deserve some suspicion. Recording all day spends power every day, and a solar camera can only spend what the panel puts back. So the battery and panel pairing is the figure that decides whether the "AOV" on the label is real or a mode the camera abandons on the third overcast night.

Our catalogue holds 150 SKUs in total, of which 49 are AOV models, across four series. These are the exact numbers:

The full range runs from 8000mAh to 20000mAh of battery and from 8W to 15W of panel. Nothing exists above that, and if any supplier's datasheet promises far greater capacity in the same housing format, it is worth asking for the cell sheet before you buy. Standard resolution is 1080p to 2K; 4K is only built as a custom or OEM development.

When you need the 20000mAh, 15W version

The practical rule is the sunlight at your site, not the price. 8000mAh with an 8W panel is more than enough on an open roof, in a region with steady sun, with the camera facing south in the northern hemisphere or north in the southern. 20000mAh with 15W buys you headroom: yards shaded for part of the day, a long rainy season, mounting under an eave or among trees, or simply not wanting to think about the battery level again. A model like the SG-D42G-15F66-V1 is built for exactly that scenario, with dual 2.0MP×2 optics and an IP66 rating.

If power is the part that worries you, it is worth reading separately about what an AOV battery is and how its draw is managed.

How to read an AOV datasheet without surprises

Four checks before you decide:

1. Is the AOV continuous, or is it "event plus thumbnail"? Some cameras call AOV a mode that records frequent clips and saves still frames in between. That beats pure PIR, but it is not a continuous tape. Ask the question directly.
2. Do the battery and panel match each other? A big battery with a small panel never replaces the daily draw; a big panel with a small battery will not carry several sunless days. The combinations in the table above are paired deliberately.
3. How much local storage does it take? The standard across our models is microSD up to 128GB, with loop overwrite: the card fills and the oldest footage gives way. The AI-marked events are what you go looking for first, so the marking matters as much as the capacity. If you need larger cards, that is a custom order, not a catalogue item.
4. What environmental rating does it declare? Every outdoor AOV model is IP66. That is the specification we publish and the one that holds; a higher ingress rating means a different housing and different sealing, and it should never be assumed.

And one running cost that sometimes gets forgotten: the camera uses 4G LTE, so it needs a SIM with a data plan. That monthly charge belongs to your local carrier, not to us, and it varies a great deal by country and by plan. Price it with the operator before you install a fleet.

Choosing between single, dual and triple lens

• Single lens (SG-C41G-10T66-V series, 4 variants).* One defined watch point: a door, a gate, a depot entrance. It is the simplest option and the one that asks least of the user.
• Dual lens (SG-D42G-10F66-V with 18 variants and SG-D42G-15F66-V with 16 variants).** Two complementary fields of view, typically one wide and one for detail, or two directions from a single pole. It is the most requested format because it covers the access point and its surroundings with one installation and one SIM.
• Triple lens (SG-S43G-10T66-V series, 11 variants).* Wide coverage from a single mast, useful on property corners, internal road junctions or turning yards where you would otherwise need two or three cameras.

In all three cases installation takes 5 to 10 minutes per camera: no mains wiring, no dependence on WiFi, the link is 4G. And in all three cases the warranty is the same — 24 months on every product, with no tiers and no extensions. Service starts with remote video diagnosis, and if a manufacturing defect is confirmed, replacement parts or a replacement unit are sent at no charge.

On lead times, so you can plan: samples in 7 to 10 days by air, volume orders in 25 to 40 days by sea, and within Vietnam 7 to 10 business days.

What AOV does not promise you

Honesty first, because a misplaced expectation turns into a return. AOV does not mean a maintenance-free camera in a place with no sun: if the panel never sees direct light, no battery capacity solves that in the long run. It does not mean unlimited sharpness either — the standard is 1080p to 2K, and 4K exists only as a custom build. And it does not replace good placement: a badly aimed AOV camera records 24 hours of a wall.

It is also worth being clear that AOV is not a quality badge. It is a description of how the camera records. Quality comes from the sensor, the optics, the firmware and the manufacturing — in our case, production at our factory partner Shenzhen Leksell, TÜV Rheinland certified and established in 2012, with CE, FCC and RoHS. If you are comparing suppliers and want to see how this is assessed from the sourcing side, there is a specific read on AOV solar cameras, "AI" labels and supplier comparison for importers, and a more general one on what Always-On Video means and how to pick a model.

If what you need is a few units for a farm, a site or a shop, any of the four series will do the job, and the decision comes down to how much sun the mounting point gets and how many angles you want covered. If your case is resale, a project or your own brand, the wholesale programme covers catalogue orders from around 10 units and OEM or private-label development from 100 units; quantity pricing comes from a person on the team, not a table on the website.
