for DDNs account you would have to go to the network part, and click on the DDNS box to deactivate it there you would unsubscribe from the epcom servers service .. port and public IP openings you could enter without problem as long as you open ports , the part of the EVIZ or HIkconnet deactivates the platform service .. The detail here would be to see which email account they registered to activate that service that you could check directly on the mobile device go to the option to recover pasword. the client at the time of configuring it to the cell phone, was given to have requested some data ... verify user .. try to remember some data email, cell number, or email address. to be able to link ... Anyway, tomorrow I speak with syscom, I am an authorized distributor and I investigate and share the info ... regards.
