Knowing the model of your router doesn't help configuring your DVR.
So please provide a link to the user manual of your DVR and mention the page where it tells how to choose between DHCP or a manual IP-address. Without IP-address it can't communicate with the router.
I just bought a DVR & some cams.
I have connected the cams to the DVR and those are working fine, as I see in the external display.
But, I want to stream the video in the net through my ADSL connection, so I can log in to the IP and watch any time I want.
I am using a D Link DSL 2750U/4 port/wireless router.
Any earliest reply would be appreciated.
Thanks in advance.
