Router Port Forwarding (Step #4)
You will need to enable port forwarding on your Router to allow for external communications with your
Observation System for ports:
PORT 8841
Computers, DVRs, and other devices inside your network can only communicate directly with each other
within the internal network. Computers and systems outside your network cannot directly communicate
with these devices. When a system on the internal network needs to send or receive information from a
system outside the network (i.e. from the Internet), the information is sent to the Router.
When a computer on the Internet needs to send data to your internal network, it sends this data to the
external IP address of the Router. The Router then needs to decide where this data is to be sent to. This
is where setting up Port Forwarding becomes important.
Port Forwarding tells the router which device on the internal network to send the data to. When you set up
port forwarding on your Router, it takes the data from the external IP address:port number and sends that
data to an internal IP address:port number (i.e. Router External IP 216.13.154.34:6100 to DVR Internal IP
192.168.0.103:6100).
The instructions found online in the Router Configuration Guides will assist you in the port forwarding
configurations for a selection of different router models. Visit our Consumer Guides Support website at
