Hi all - first real post, please go easy 
Just getting a Hikvision cam setup. I configured port forwarding in my Mikrotik and have the app and web access working properly.
Utilizing both live and recorded playback - I do not see any packets flowing over this port. What is it used for? If it is not used in my setup I would prefer to close the port.
Thanks!
