KL-LED-STR78 / DTR78 with 4K Camera System

Q: What is the KL-LED-STR78&DTR78 Camera System used for?

The KL-LED-STR78&DTR78 is a ceiling-mounted LED operating lamp with an integrated 4K HD camera system. It simultaneously provides shadowless surgical illumination and high-definition real-time imaging of the operative field, supporting surgery, documentation, and surgical education in modern operating rooms.

Q: What is the difference between the STR78 and DTR78 configurations?

The KL-LED-STR78 is a single-head operating lamp with camera, while the KL-LED-DTR78 is a dual-head (main plus satellite) configuration. Both share the same 4K camera platform and imaging specifications; the dual-head variant adds a second lamp head to increase illumination coverage for larger operative fields.

Q: What camera output and resolution does the system provide?

The integrated camera outputs 1920 × 1080 HD video via a 3G-SDI MCX female connector. Frame rates are PAL 25/50 fps or NTSC 30/60 fps, with 10× optical zoom and signal-to-noise ratio exceeding 50 dB, suitable for high-fidelity surgical documentation and live streaming.

Q: Can distributors order the KL-LED-STR78&DTR78 Camera System in bulk or OEM?

Yes. Keling Medical supplies hospitals, medical equipment distributors and project contractors worldwide through its Shanghai sales and export center. OEM and wholesale enquiries are welcomed; contact Keling Medical via https://www.keling-surgicallight.com/contact/ for project pricing and specifications.

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.
