    WiseStream II


    Wisenet Video Compression Technology

    As the video data size handled by video surveillance increases, the importance and necessity of data reduction techniques increase as well.

    The large scale of the original video data calls for effective data compression to enable efficient network streaming. WiseStream II is a technology that effectively reduces the data size while maintaining image quality.

    It can reduce data size by more than 50% when used with the H.264 codec, and has an additional data savings of 25% or more when used with H.265. It can further provide up to 99% data reduction in low-motion scenes.

    Reduce the data size without comprising image quality

    Hanwha Techwin WiseStream II is an advanced video compression technology based on motion analytics to maintain video quality while lowering data demands. While WiseStream II works with both H.264 and H.265, it is more effective with H.265. WiseStream II reduces noise and minimizes image quality degradation, which are common problems of traditional image compression artifacts and image noise in low light settings.
