The Qihan "Diamond” series of HD network camera adopts the latest Grain Media master chip designed to work with most professional security image sensors on the market and to generate clear images in resolutions of 720P, 960P, 1080P and 4K comprehensively. The series or HD network cameras supports standard H. 264 high profile 4.0 compression technology that features higher compression ratio, higher accuracy, and stable flow control. The Diamond-series cameras are compliant with ONVIF 2.4 technology and standards that greatly improve the compatibility performance and fully support PoE, Wifi, 3G network connectivity. Since being launched on to the global market, the Diamond series has won a good deal of immediate positive response worldwide according to Qihan.

It offers powerful functions of POC, COC, AOC, motor-driven lens control and so on. The system significantly improves the integration and transmission of HD video, audio and control technology so that it can be widely used in more intelligent HD security video surveillance equipment fields.  Based on the 2nd generation of HD-SDI technology and system design architecture, the HDFDI system features higher system compatibility, higher efficiency, and yet at lower cost; these characteristics make the HDFDI system the most cost-effective solution with a pleasant user-experience for end-users.
