LN330-4K30F (1/1.8" CMOS) Technical Overview
4K30p Ultra HD Camera with 3G-SDI & HDMI Outputs
The Lntech LN330-4K30F is a professional-grade Ultra HD camera
designed for integration into broadcast, live event, and high-end
security systems. It utilizes a 1/1.8-inch 8.29-megapixel CMOS
sensor to capture video at 3840x2160 resolution (4K) at 30 frames
per second, or downscaled 1080p at 50/60fps. Its key feature is the
provision of dual 3G-SDI and HDMI outputs, offering simultaneous
connectivity for monitoring and recording. Comprehensive image
control is provided via an OSD menu and RS-485 interface,
supporting a wide range of professional adjustments and remote
operation.
In-Depth Technical Analysis
1. Imaging Performance & Sensor
The camera is built around a 1/1.8-inch CMOS sensor with 8.29 million effective pixels. This sensor size offers a superior balance between light
sensitivity and form factor, capable of producing detailed 4K UHD imagery. The scan system is progressive, ensuring sharp,
non-interlaced video.
2. Video Outputs & Compatibility
3G-SDI Output: Provides a robust, long-distance signal transmission option.
Operates in EX-SDI mode for 4K/30p output and switches to HD-SDI (HD/PK) mode for 1080p/50/60p output, ensuring compatibility with a wide range of broadcast
equipment.
HDMI Output: Offers a simultaneous digital output for local monitoring or
connection to HDMI-based recorders and displays. Output resolution
mirrors the SDI output settings.
3. Image Processing & Control
Exposure Control: Features multiple modes including automatic electronic shutter,
manual brightness adjustment, Backlight Compensation (BLC), and Automatic Gain Control (AGC).
Day/Night Functionality: An automatic ICR (Internal Cut Filter Removal) filter provides true day/night operation, switching to monochrome
mode for enhanced low-light sensitivity.
Color & Detail: Manual White Balance control and Saturation adjustment allow for precise color grading. Detail enhancement and Noise Reduction settings provide control over image sharpness and clarity.
Advanced Features: Includes Privacy Masking to block sensitive areas and Digital Zoom for framing adjustments.
4. System Integration & Operation
Control Interface: The RS-485 serial interface supports standard PTZ control protocols, enabling
integration with joystick controllers and video management systems.
OSD Menu: A full-featured menu system accessed via front panel buttons
allows for in-depth configuration of all image and system
parameters, including camera ID, output standard, and language.
Power & Environment: Operates on standard 12V DC power and is designed for reliable performance in a wide operating temperature range (-20°C to +80°C).
