3-7-1. Ports
Port-Forwarding for Access from a WAN
When one or more DVRs are connected through a IP sharing device (i.e. router) to a larger network (i.e. the
internet), in order to access each unit from outside the local area network, each device must have a unique
RTSP (Real Time Stream Protocol) and HTTP port number. You must also configure your IP sharing
device for port-forwarding, so that each port, when accessed on the IP sharing device, will forward to the
appropriate DVR’s IP and or MAC address. The port number is listed next to the “Port” menu option in the
Network menu
.
If you only plan to access multiple units from within a local area network, you do not need to change
the RTSP and HTTP port numbers, unless other IP sharing devices are established in-between the
client and the DVRs.
To access the DVR, you must have the following information:
