As far as we are aware there is no way to make the stream on Hik-Connect or in a browser stay always live 24/7, the only way to have a stream displayed 24/7 is to connect a direct HDMI/VGA monitor to the NVR.
I manage to open port 10554 in my Modem, and now I can acess to my Hikvision over internet direct. And I can have picture as I am on my LAN. But I must write my IP adress of modem because my ISP Provider reset my IP adress every 24h. So every day my son have to open https://whatismyipaddress.com/ and send me new IP Adress. How can I connect direct vithout IP change?
BTW I know for No IP, but I dont have computer that is Allways powered On at home
