3-5-1. Port
When connecting 1 or more DVRs to a network through an IP sharing device, each device must
have a unique RTSP port number for access to each unit from outside the LAN. Also, the IP
sharing device must be configured for port forwarding, so that each port, when accessed on the
IP sharing device, will forward to the appropriate DVR. This port number is listed next to the Port
menu option in the NETWORK menu. If the user plans to only access the units from within the
same local area network, the RTSP port does not have to be changed.
Network access beyond Router
In order to access beyond Router (Firewall), user must open 1 TCP port. If this port is
not open properly, user can not access DVR beyond a router.
If DVR sets port number with 5445, user has to open 5445 TCP port of your Router.
