Reolink Duo 3V PoE vs RLC-811A
Duo 3V PoE is designed to replace two adjacent wide cameras with one stitched 180° view. RLC-811A does the opposite: it narrows the scene with 5× optical zoom to concentrate pixels on a smaller target area.
| Feature | Duo 3V PoE | RLC-811A |
|---|---|---|
| Resolution | 16MP dual-lens | 8MP 4K |
| Horizontal coverage | 180° panoramic | 105°–31° |
| Optical zoom | No | 5× |
| Power | PoE | PoE |
| Local storage | microSD / NVR / FTP | microSD / NVR / FTP |
| RTSP / ONVIF | Supported in documented wired Reolink workflow | Supported |
Choose Duo 3V when blind spots are the main problem
A 180° camera is useful on a broad front elevation, large yard or building corner where two normal cameras would otherwise overlap. Its value is coverage efficiency, not telephoto identification.
Choose RLC-811A when one specific zone matters
For a gate, license-plate lane or long driveway, the narrower 31° end of the RLC-811A can put far more pixels on the evidence zone than a panoramic camera.
Verdict: broad situational awareness → Duo 3V PoE. Focused identification and adjustable framing → RLC-811A.
