Qihan Technology Co., Ltd

Recently, leading security equipment and solutions provider – Qihan, introduced the first domestic market oriented HDFDI optical fiber box camera - Model QH - FB441 – V. The product with industry-leading HDFDI HD fiber transmission technology, at the same time, with high-performance 1/2.5 "progressive-scan CMOS sensor, image clarity is exquisite, color reduction degree is high, support 1080 p standard HD-SDI HD video transmission, fast without delay, up to 20 km HD fiber optic transmission, bringing clients a whole new generation of China's first 20 km high-definition video surveillance transmission solution.

HDFDI technology Define new standard HD transmission

The product based on the Qihan science and technology research as well as development of a new generation of optical transmission protocol HDFDI, can output 2 million pixels without full HD real-time video compression, the maximum transmission distance of 20 km. HDFDI as a new generation of high-speed interconnection technology, with low latency, bandwidth, high speed, strong anti-jamming capability, long transmission distance, the reliability of the transmission loss less transmission characteristics.

High-definition image & real-time transmission

Products developed by Qihan has unique and the world's best horizontal resolution and a high level of image quality, using the ultra precise image analysis technology, 2D noise reduction and adaptive image processor technology, image resolution is 1920 x1080 (2 million pixels), support the original compressed video information real-time output, free from extreme image resolution and image quality.

Efficient infrared & real reduction

Using ICR infrared filter plate automatic switching, according to the strength of the light day and night, it can automatically adjust the color and black and white, compare with the traditional single filter, In addition, the camera support infrared light, enhancing the image color reduction degrees during the day, but also improves the night vision environment the sharpness of the picture.

Product also has the following features:

·1080P HD standard HD-SDI video output
·1/2.5 "progressive scan CMOS
·The original uncompressed video information in real output
·OSD menu support
