Is the port open on your home PC/LAN? Do you have the correct software to be able to view video from the CC setup? Depending on the product, you may need to install an ActiveX control or other software to view the video output.

Check the documentation and software provided with the CCTV system, or the manufacturer's website.

OK thanks but how can i check if the port is open or where can i open it ?

May be what i need to do first is able to access my router from outside the LAN when typing in the URL which i get from dyndns.com.

thanks

You'll have to follow the manufacturer's instructions for your router and CC setup.

The camera would send video on a particular port, or you choose one. Make sure that post is open for that device on the router. If you never accessed your camera from outside the LAN before, this is probably not set. You need to open the same port on your home router and firewall if you have either.

If it is a web-enabled security camera, it probably uses port 80. Again, check with the CC manuals to see if you need a client program installed on your home computer to view the video.
