Section 4 - Configuration
Note: You MUST also set up your router/gateway for Port Forwarding/Mapping; this will enable remote viewing of your camera via the Internet. Please
refer to your router's instruction manual on how to open up ports (port forward). For additional help on configuring your camera to work with your router,
please refer to Appendix A: Installing the DCS-5211L/DCS-5222L on a Router Without UPnP. For installing multiple cameras, ONE port per camera
must be opened on your router, the Web server (HTTP) port. Also, some browsers may restrict some ports, such as 1 or 22, for security purposes. If you have
problems accessing your camera through HTTP, try using a port higher than 1024.
After making any changes, click the Save Settings button to save your changes, or click the Don't Save Settings button to discard your changes.
