The firewall security features built into the router prevent users from accessing the video from the D-Link DCS-5220 over the Internet. The router connects to the Internet over a series of numbered ports. The ports normally used by the DCS-5220 are blocked from access over the Internet. Therefore, these ports need to be made accessible over the Internet. This is accomplished using the Virtual Server function on the router. The Virtual Server ports used by the camera must be opened through the router for remote access to your camera.
**In this example, we are using the D-Link DI-624. The Virtual Server interface may differ depending on your router**.
Follow these steps to configure the Virtual Server settings of the DI-624:
Step 1: Open a web browser such as Internet Explorer and enter the IP address of your router (192.168.0.1). Enter username (admin) and your password (leave blank).
Step 2: Click on the Advanced tab and then the Virtual Server button on the left.
Step 3: Click Enabled.
Step 4: Enter a different name for each entry.
Step 5: Enter your camera’s local IP Address in the Private IP field.
Step 6: Select TCP for HTTP port, both (TCP and UDP) for RTSP and both (TCP and UDP) for 5556 – 5559 ports.
Step 7: If you are using the default camera port settings, enter 80 into the Public and Private Port section, click Apply.
Step 8: Scheduling should be set to Always so that the camera images can be accessed at any time.
Repeat the above steps adding the port 554 to both the Public and Private Port sections. A check mark appearing before the entry name will indicate that the ports are enabled.
Important: Some ISPs block access to port 80 and other commonly used Internet ports to conserve bandwidth. Check with your ISP so that you can open the appropriate ports accordingly. If your ISP does not pass traffic on port 80, you will need to change the port the camera uses from 80 to something else, such as 800. Not all routers are the same, so refer to your user manual for specific instructions on how to open ports.
Enter valid ports in the Virtual Server section of your router. Please make sure to check the box next to the camera name on the Virtual Server List to enable your settings.
