Apologies for not replying sooner, never got notification you had replied gem1919. Update on my ticket today actually which had a resolution similar to what you have said. The problem is related to “LocalServiceControl” which is downloaded/installed when you access the NVR for playback. Solution is to add exclusion for IP of NVR to the above application. Settings, Application Control,, Manage Applications Top right, search for "localservicecontrol", Right click and select "Details and Rules", then select "Exclusions". Tick/select "Do not scan all traffic" and also tick "Only for specified IP address". Add the IP address for your NVR. Save and your done.

Hi Igor Thanks for your inputs thus far. Ticket INC000012270612 raised. Martin

Hi Igor Pausing protection, restarting browser makes no difference. While you have mentioned resetting the configuration settings to default, I should point out that I have another PC that I recently performed a fresh Win 10 install along with KIS 21 and that PC also exhibits the same issue. The Hikvision NVR is accessed via normal web browser using IP address. It is however an unsecured connection if that makes any difference to what KIS is doing. You would think that pausing protection should be enough but KIS must still be protecting something which is only released on complete exit. Martin

Yes, makes no difference. Even if you disable Web Anti-Virus, Firewall it still blocks playback

Did you get this resolved? I have a similar issue with playback from Hikvision cameras since KIS was updated to version 21. I’ve traced it back to the fact that incoming steam under port 80 TCP is being blocked for some reason. Under Configuration and then local from the Hikvision NVR webpage, change Protocol from TCP to UDP. This will then allow playback streaming to work. While this fixes the issue something has changed in KIS. Do not know if this is a bug or new behavior.
