    Hi Gyver,

    Given the fact that Hikviksion also supports native H.265, which is an industry-standard, what would be the advantage of adding a proprietary format like H.265+?

    I have some basic Hik's at home and enabled the H265+ from normal H265 on the camera's and it made a difference with  storage dramatically. maybe its just a different profile based on the h265 codec ? I personally don't know.. but my nxwitness just worked and the space saving was great. Given that you can get a free 30day demo.. maybe give it a try ? 

    I was running the 8mp. & 6mp Turrets.

    Hi Greg, 

    Thank you for your feedback. The H265+ is a proprietary format for Hikvision and no derivate of the official H.265. 
    I have tested a lot with H.264, H264+, H.265 and H.265+ and sure there are differences in bandwidth and thus storage there also a big difference between the image quality. 

    For scenes with not too much movement, de + versions have some advantages when it concerns bandwidth, but on the average scene where there is more movement (retails, logistics, hotels, etc) the differences are minimal or even opposite.

    Hi Norman,

    I understand that H265+ is a proprietary format. I own primarily Hikvision cameras, over 50 cameras to be exact, however, different stores have different budgets and hence are unable to purchase NX Witness license due to the high costs, hence, went for Synology instead.

    Here are some info regarding the recorded storage of both H265 and H265+. The cameras and scenes are different hence it's hard to make a comparison, I will try to do dual recording to both H265 and H265+ and post more accurate comparison, however, the differences are vast according to my experiences.

    I have this Hikvision Camera (2688x1520), recoding on NX Witness 24 hours a day at H265, with no movement from 10pm to 6am, taking up 1.04TB over 25 days, averaging 40GB a day.

    On the other hand, I have another HikVision Fisheye camera(2048x1536)also recording 24 hours a day on a Synology Survilliance Station at H265+, with no movement from 10pm to 6am taking up 123gb over 15 days, averaging 8.2gb a day.

    Both cameras have lots of movement, the first being a storefront and the second being an office lobby with people walking around all the time. 

    Comparing 40gb to 8gb, that's a huge 80% saving moving from H265 to H265+. Bandwidth viewing the H265+ camera is 2mbps max while viewing the H265 camera can take up to 8mbps max.

    If possible, I would like to do dual recording to 2 different formats to have a more accurate finding. However, given that both cameras with relatively similar resolution have a difference of ~80% disk savings is a huge thing, imagine how much disk space we save with H265+.
