Section 4 - Security
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.
