- Camera output interface is 3G-SDI (MCX female connector), supporting PAL 25/50 fps and NTSC 30/60 fps at 1920 × 1080 resolution.
- Signal-to-noise ratio is >50 dB; aperture range is F1.6–F3.0; horizontal field of view spans 58.6–6.4 degrees (wide-telephoto).
- The system includes LED operation lamp head, ceiling suspension arms, built-in HD camera, central camera, panoramic camera, recording server and HD medical monitor.
- The Keling KL-LED-STR78&DTR78 is produced by Keling Medical, a Chinese medical equipment manufacturer with more than 20 years of industry experience and an ISO 13485-certified factory.
Overview
The KL-LED-STR78&DTR78 Camera System brings together shadowless LED surgical illumination and a 4K digital HD camera in one ceiling-mounted platform, giving operating room teams both optimal lighting and real-time high-definition visualization of the surgical field. The STR78 single-head and DTR78 dual-head variants share an identical imaging core, letting hospitals choose the lamp configuration that suits their suite layout while retaining the same documentation and teaching capabilities.
The imaging subsystem is built around a model MH-DFC210-SR 4K surgical field camera equipped with a 1/2.8" Progressive Scan CMOS sensor, 10× optical zoom, and a 3G-SDI output interface for lossless high-bandwidth transmission to the bedside monitor. Focus can be set to Auto, Semi-auto or Manual; electronic shutter range spans 1/25 s to 1/100,000 s; digital noise reduction offers Off, Normal and Expert modes; and scene modes include Normal, Constant-brightness, Shadowless Lamp and Stroboscopic to match varied intraoperative conditions. White balance offers Auto 1, Auto 2, Manual and One-touch options, while image quality adjustment covers brightness, contrast, sharpness, saturation and chroma.
An HD medical monitor paired with the built-in central camera provides real-time visualization and team collaboration, while a panoramic camera and dedicated recording server support image capture, video recording and external storage for documentation, training and telemedicine. Multi-joint suspension arms with smooth movement and stable positioning allow the lamp head to be repositioned without vibration, keeping the surgical field in sharp focus throughout each procedure.
Key Features
- 4K Ultra-HD Imaging — high-resolution 4K camera captures surgical detail with exceptional clarity and true color reproduction for confident intraoperative decision-making.
- Integrated Camera System — built-in camera and HD display allow seamless capture, viewing and knowledge sharing without additional ceiling-mounted equipment.
- Shadowless LED Illumination — advanced LED lamp head delivers high-brightness, even light with adjustable color temperature, eliminating shadows in the surgical field.
- 10× Optical Zoom — focal length 4.7–47 mm, aperture F1.6–F3.0, horizontal FOV 58.6–6.4°; covers both wide-field overview and close telephoto detail.
- 3G-SDI Output — MCX female connector transmits full 1920 × 1080 at up to 60 fps (NTSC) over a single cable to the bedside monitor.
- Flexible Positioning Arms — multi-joint ceiling suspension arms with smooth movement and stable locking allow precise repositioning during procedures.
- Recording Support — onboard recording server supports image capture, video recording and external storage for documentation and surgical education.
- Safe & Durable Design — medical-grade materials and stable structure; modular design facilitates quick service and easy maintenance.
