LF-920 is independently developed by Shenzhen Qianhai Linghao Technology Co., Ltd., and has a high-definition conference network camera with independent intellectual property rights. It has a built-in 20x optical zoom lens, powerful HD image engine, wide dynamic range and high signal noise. The image imaging algorithm is combined with the unique 2D/3D noise reduction algorithm to provide users with 1080P60 full HD broadcast image experience.

The LF-920 delivers quiet, high-speed pan/tilt operation and wide-area object capture, saving up to 255 presets, combined with an excellent pan/tilt design that provides superior external/remote control Positioning characteristics.

The LF-920 can output digital HD images through HD-SDI and HDMI interfaces, as well as a video and audio encoding engine. It supports the industry-leading H.265 video encoding, and outputs multiple channels of video and audio streams through a network interface. The mainstream network communication protocol is the perfect combination of HD conference cameras and network cameras.

The LF-920 works seamlessly with the industry's leading codecs, video conferencing terminals, and other video systems. It is an ideal choice for professional video conference room integration, video conferencing, distance learning and industry recording applications.

Features:
□ 1080P60 full HD broadcast image
Built with a 1/2.8-inch HD CMOS sensor, combined with a powerful image engine and imaging algorithms, it delivers a full HD broadcast-quality image experience of up to 1080P60.
□ “Secret and far-reaching” visual enjoyment
Wide dynamic range, high signal-to-noise ratio image effect, combined with the unique 2D/3D noise reduction algorithm, greatly reduces image noise, keeps the picture clean and clear in low-light environments, and provides "quiet and far-reaching" visual enjoyment.
□ 240 times zoom range
Equipped with a high-performance motorized zoom lens with up to 240x zoom (20x optical + 12x digital).
□ New generation H.265 coding
Built-in video and audio encoding capabilities, support H.265/H.264 video encoding and G.711/G.726 audio encoding, enabling 1080p full HD ultra-low bandwidth transmission.
□ High speed and accurate pan/tilt positioning
With the new stepping motor, the pan/tilt is quiet and stable, and the positioning is accurate and rapid. The maximum speed can reach 200 degrees/second.
□ Multi-channel simultaneous output video interface
Multi-channel high-definition video output interface (3G-SDI, HDMI, IP network) provides simultaneous high-quality image transmission.
□ Rich and complete external control
Support RS232, RS485 and IP interfaces, compatible with all kinds of mainstream communication protocols, can achieve full and flexible control of the camera.
□ Convenient and flexible installation and use
Chinese and English on-screen menu, with multi-function infrared remote control, easy and flexible operation. Support a variety of installation methods (dressing / ceiling / wall / boom, etc.).
