**9007.10 – cinematographic cameras**
- **Defining trait:** Built for professional film production, capturing high-resolution motion pictures.
- **Typical examples:** Arri Alexa, RED cinema cameras.
- **Best fit when:** Used in movie-making or cinematic video projects.
**9013.80 – night vision cameras**
- **Defining trait:** Uses infrared light to capture images in low-light or total darkness.
- **Typical examples:** Military night scopes, surveillance cameras with IR.
- **Best fit when:** Operates in dark environments without visible light.
**9022.19 – X-ray diffraction cameras**
- **Defining trait:** Uses X-rays to analyze crystal structures; not for visual imaging.
- **Typical examples:** Laboratory instruments for material science.
- **Best fit when:** Used in scientific analysis, not for photography or surveillance.
**9031.49 – measuring cameras**
- **Defining trait:** Designed to capture images for precise dimensional measurement.
- **Typical examples:** Photogrammetry systems, industrial inspection cameras.
- **Best fit when:** Used in engineering, surveying, or quality control.
**Photographic (other than cinematographic) cameras...**
- **Defining trait:** Captures still images using film or digital sensors for general photography.
- **Typical examples:** DSLRs, mirrorless cameras, instant cameras.
- **Best fit when:** The primary purpose is taking still photos, not video or specialized detection.
## Key differences
| Option | Primary Use | Light Source | Output Type | Special Feature |
|-------|--------------|---------------|----------------|------------------|
| Video cameras | Recording motion | Visible light | Continuous video | Real-time capture |
| Television cameras | Broadcast TV | Visible light | High-quality video | Studio integration |
| Doorbell cameras | Home security | Visible/IR | Video + alerts | Doorbell integration |
| Cinematographic | Film production | Visible light | High-res film | Professional-grade |
| Night vision | Low-light imaging | Infrared | Monochrome video | IR illumination |
| X-ray diffraction | Scientific analysis | X-rays | Data (not image) | Crystal structure analysis |
| Measuring cameras | Precision measurement | Visible/IR | Measurable images | Calibration for geometry |
| Photographic cameras | Still photography | Visible light | Still images | Image quality focus |
## How to choose
- Does it capture moving images? → 8525.8X (video)
- Is it used in film or broadcast TV? → 9007.10 (cinematographic)
- Is it part of a doorbell system? → 8525.89 (doorbell camera)
- Does it work in total darkness using infrared? → 9013.80 (night vision)
- Is it for measuring physical dimensions? → 9031.49 (measuring camera)
- Does it use X-rays to analyze materials? → 9022.19 (X-ray diffraction)
- Is it for still photos, not video or specialized use? → Photographic cameras
## Overlaps & pitfalls
- A night vision camera may also be a video camera (e.g., IR security cam). Prioritize **main function**: if it's for surveillance with motion alerts, choose 8525.89; if for low-light imaging, 9013.80.
- Some cameras (e.g., doorbell) may also have night vision or video — use the **primary purpose** to decide.
- "Photographic" includes instant print and medical cameras — avoid confusion with scientific or measuring devices.
- No option is vague; all are clearly defined by function
