SV-D2
Dual-lens solar 4G camera (SV-D2)
The SV-D2 puts two cameras in one body: a fixed lens that always watches the gate or fence line, and a pan-tilt lens that turns to follow. One SIM, one 5 W panel, two live pictures in the app.
- 2MP + 2MP lenses
- Linkage + picture-in-picture
- 5 W separate panel
- 7,800 mAh battery
- Samples from 2 units; mixed models count towards price tiers.
- Band version for your country printed on the carton with the IMEI.
- Pairs with the Tuya Smart / Smart Life app.
Who the dual lens solar 4G camera is for
Choose it for
- Kraals, bomas and fence lines where the gate must stay covered while the camera follows a person
- Orchards and shops where a single turning camera would leave the entrance unwatched
- Resellers who want a step up from single-lens models
Choose another model for
- Very small budgets where one turning camera is enough (use the SV-P1)
- Wide yards with three or more approach routes (use the SV-M3)

Figures are from the factory catalogue for the 4G version. Standby time is with no sun and the camera waiting for alerts; live viewing uses the battery much faster.

Dual-lens solar 4G PTZ cameras on Alibaba list at about $20.60–$30.40 per unit, the lowest only at 1,000 units or more, while multi-lens models with larger batteries reach about $36. The SV-D2’s 5 W panel and 7,800 mAh pack put it at the upper end of the dual-lens range. We price level with that market rather than below it.
Why two lenses help on a farm
A single pan-tilt camera can only look one way at a time. If it turns to follow a goat at the far end of the paddock, the gate behind it is unwatched. Livestock theft usually happens at night through a gate or a cut fence, so many farmers want the entry point watched all the time and a second view they can move.
The SV-D2 does both from one pole and one SIM. The fixed upper lens keeps the gate in view; when it sees a person, the lower lens turns to follow them, and the app shows both pictures at once.
Power and data with two lenses
Two image sensors use more power and more data than one, which is why the SV-D2 uses the larger 5 W panel and the 7,800 mAh pack. On cloudy weeks the app can be set so the camera records only on alerts. Our SIM card guide has data estimates for both cases.
For resellers and installers
Dual-lens cameras are now the common step up on Jiji listings in Kenya and Nigeria, so buyers recognise them. Cartons carry the band version and IMEI, and mixed orders count towards the same price tiers.
