I'll be glad to try and help.
If you login to your DVR and go into Menu and then go to >Setup>Network>network tab; you should see a page similiar to this ->
Take note of the http port and server port as you'll need both of these for the port forwarding.
*I would also advice to set a static ip address in the network page of the dvr and not use dhcp. Having a static address will make management and troubleshooting easier.*
After you've wrote down the 2 ports you'll need please login to your router.
Typically the ip address is 192.168.1.1 but yours may vary depending on how you have it setup.
Once you are logged into the routers administration page please go to the Advanced Setup page which should look something like this ->
The starting point for the first port you'll be forwarding is 80. So input 80 as the starting and 80 as the ending. Protocol will be tcp, and lan ip address will be ip address of the dvr.
Once you have that done please click apply. It may refresh the page for you to input any more ports that need to be forwarded. Now you'll need to enter 6036 for the starting and 6036 as the ending, protocol will be tcp and lan ip will be ip address of the dvr. Once done click apply. That's it and you should be done with the forwarding.
Now try to enter the ddns entry you created in a web browser or your phone and see what happens. You'll need to either type :80 or :6036 at the end of the ddns entry for it to work. Example would be http://www.mydvr.com:80 or http://www.mydvr.com:6036
*REPLACE mydvr.com with your DDNS entry*
Here is something you can do as well that may make it simpler
Login to the dvr and go to the network settings again. You should see a page like this ->
Go to Other Settings and input your DDNS information that you created. Once everything is filled out click TEST to test the effectiveness of the relevant information. If everything checks out good then Apply and Exit.
