What is Zenmuse H20N

• The Zenmuse H20N is a hybrid “night‑vision + thermal + zoom + laser‑rangefinder + RGB” payload from DJI — built for enterprise drones (e.g. DJI Matrice 300 RTK / M350 RTK).

• The “N” stands for Night vision — meaning its visible‑light cameras are optimized (with special “starlight sensors”) for very low‑light / night conditions.

 Key Cameras & Sensors / Capabilities

The Zenmuse H20N packs several sensing/imaging modalities in one compact payload:

• Wide‑angle RGB camera — 2 MP sensor, lens covering ~73.6° field‑of‑view. Good for broad-context visuals even at night.

• Zoom RGB camera — 4 MP sensor, with 20× hybrid‑optical zoom (and up to 128× max zoom). Aperture wide enough (f/1.6 in night mode) so it works well in low light.

• Dual Thermal Cameras (infrared) — two thermal imagers (uncooled VOx microbolometers), giving both a “wide thermal view” and a “telephoto thermal zoom.” Thermal resolution: 640 × 512 px.

• Laser Rangefinder — built-in, measuring distances from ~3 m up to 1200 m. Useful to get precise range / coordinates of objects or heat sources detected by thermal/vision.

• Starlight / Low-light Night Vision — the RGB cameras are specially tuned to detect and provide clear images even under minimal lighting (e.g. dark, nighttime).

• Durability & Environmental Specs — Weight: ~ 878 g; Protection rating: IP44 (resistant to some dust & water spray); Operating temperature range: –20 °C to 50 °C.

So overall — H20N is a multi‑sensor payload: visible‑light (wide + zoom), thermal, night‑vision + laser ranging — all in one unit.
