How surgical light camera systems work, which specs matter (sensor, zoom, 3G-SDI output, frame rate) and what to plan before installation.


Operating-room video used to require a separate boom-mounted camera. Today the camera can sit **inside the surgical light system**, aligned with the light beam and therefore with the surgeon's line of sight. Keling offers two such systems: the [KL-LED-STR78 / DTR78 Camera System](https://www.keling-surgicallight.com/products/kl-led-str78-dtr78-camera-system-led-surgical-light/) and the [KL-LED-STZ5 Camera System](https://www.keling-surgicallight.com/products/kl-led-stz5-camera-system-led-surgical-light/).

## Why integrate the camera with the light?

- **Same viewpoint as the surgeon** — the camera looks down the beam, so the field is always lit and framed.
- **One ceiling axis** — fewer booms competing for ceiling space and laminar airflow.
- **Repositioning is natural** — when the nurse moves the light, the camera follows.

## Where hospitals use it

1. **Teaching and residency programmes** — live transmission to seminar rooms or the gallery.
2. **Telemedicine and remote proctoring** — a specialist guides a procedure from another site.
3. **Documentation** — recordings for patient records, quality review and medico-legal purposes.
4. **Team awareness** — scrub nurses and anaesthetists see the field on a wall monitor.

## Specifications that matter

| Specification | Why it matters | Keling MH-DFC210-SR camera |
|---|---|---|
| Sensor | Low-light performance, noise | 1/2.8" progressive-scan CMOS |
| Optical zoom | Detail without moving the light | 10× (4.7–47 mm) |
| Aperture | Brightness and depth of field | F1.6–F3.0 |
| Output | Compatibility with recorders/routers | 3G-SDI, MCX female |
| Resolution / frame rate | Smoothness of motion | 1920 × 1080 at 25/50 fps (PAL), 30/60 fps (NTSC) |
| Focus | Hands-free operation | Auto / semi-auto / manual |
| Control | Integration with OR systems | RS-485 + infrared remote |
| Strong-light suppression | Prevents blown-out highlights under 160,000 lux | Supported |
| Image freeze | Discuss a frame during surgery | Supported |
| Power | Installation planning | 12 VDC, 1.5 A; 5.5 W |

## Installation checklist

- **Video path:** where will the SDI signal go — a recorder, an OR integration system, a hospital network encoder?
- **Cable routing:** through the suspension axis to the wall or ceiling distribution box.
- **Monitor placement:** on the light's monitor arm or a separate pendant.
- **Data protection:** agree recording, storage and consent policies with the hospital's information-governance team before go-live.
- **Training:** make sure circulating staff can zoom, focus and freeze from the remote.

## Choosing between the two Keling systems

- Pick the **STR78/DTR78 camera system** when you need round-dome heads with R9/R11 ≥ 97 tissue rendering, electric focus and up to 228 LEDs across two domes.
- Pick the **STZ5 camera system** for the five-petal-dome optical design with 45 computer-arranged LEDs per head.

Both deliver 160,000 lux per head. [Compare them side by side](https://www.keling-surgicallight.com/compare/?m=kl-led-str78-dtr78-camera-system,kl-led-stz5-camera-system) or [request a configuration](https://www.keling-surgicallight.com/contact/).


## FAQ

### What is a surgical light camera system?

It is a surgical light with a video camera mounted in the centre of the lamp head or on its own arm, capturing the surgeon's view of the operative field for live display, recording, teaching or telemedicine.

### What output does the Keling surgical camera use?

The MH-DFC210-SR camera used in Keling KL-LED-STR78/DTR78 and KL-LED-STZ5 camera systems outputs 1920 × 1080 video over 3G-SDI (MCX female connector) at 25/50 fps (PAL) or 30/60 fps (NTSC), with an RS-485 control interface.

### Does the camera have optical zoom?

Yes. The camera offers 10× optical zoom (focal length 4.7–47 mm, aperture F1.6–F3.0) with auto, semi-auto and manual focus.
