Hikvision suffered severe criticisms for its abrupt plan to discontinue its Hikvision Online service, with 3 core functions to be removed on Dec 30th.
However, all of those functionalities continue to run in 2017, including the security vulnerabilities, and Hikvision has no explanation of what will happen next.
Update January 5th, Hik-online.com is now shut down. The site is up and one can login but when doing so, it just displays the discontinuation notice with no other options - e.g., no ability to manage devices or check status. In addition, new devices cannot be added, despite the notice saying that this could be done through February 16th.
