Hi,

I'm having problem configuring and appreciate for your support. All my clients are using the Network Video Recorder (DNS-726-4) for two reasons recording and also phone viewing.

Problems

1)   In order for my clients to view all cameras over the phone, I need to open RTSP port for each camera in my router. The default port set in all D-Link cameras is 554 meaning I have to portforward 554 for all cameras IP address (Assume there are 2 cameras; Camera1 and Camera2). The problem is, one port (554) can be portforwarded to only one IP address. For instance, if I open “554” for camera1 (192.168.1.2), I won’t be able to open the same port “554” for camere2 (192.168.1.3). If I tried it will say “duplicate port error” in my router.

IE viewing: Working fine, Camera1 Http://xxx.xxx.xxx.xxx:300/  Camera2  Http://xxx.xxx.xxx.xxx:400/     (port 300 and 400 is HTTP port I set in the camera setting)   
Phone viewing: Cannot connect
Recording: All cameras connected and working fine with DNS-726-4


2)   Due to that, I’ll need to set different RTSP port for each camera. Let’s say if I change camera1 default RTSP port from “554” to “1000”, and camere2 default RTSP port from “554” to “2000” the NVR (DNS-726-4) will have problem detecting the cameras. I believe supposedly it should connect to the camera using HTTP port that I’ve set instead of RTSP port. Anyway, basically if I change RTSP to other than 554 in the camera setting, DNS-726-4 won’t be able to detect the cameras where only black screen will appear thus I’m having problem recording but I will be able to view it remotely (Desktop IE & Cell Phone).

IE viewing: Http://xxx.xxx.xxx.xxx:300/   Http://xxx.xxx.xxx.xxx:400/     (port 300 and 400 is HTTP port I set in the camera setting)   
Phone viewing: Rtsp://xxx.xxx.xxx.xxx:1000/one.sdp   Rtsp://xxx.xxx.xxx.xxx:2000/two.sdp
Recording: Nothing appeared, DNS-726-4 cannot detect both cameras

3)   The last problem I’m facing is using web server DNS-726-4. In the unit setting screen, port 5150 is set to live-viewing and  5160 is port for playback. So okay I open these two ports in my router. But when I want to view it using IE by entering http://xxx.xxx.xxx.xxx:5150/ it will show an error message “NUSP/1.0 500 CSeq: 0” and for playback when I enter http://xxx.xxx.xxx.xxx:5156/ it will show “NUPP/1.0 400 Internal Server Error CSeq: 1325142766”. So I have to open port “80” and assign it to my DNS-726-4 IP address (190.168.1.4) for me to access. Is this the only way I can remotely view my DNS-726-4 web-host by using port “80”? Why can’t I use “5150” straight because “80” normally being used for me to connect to the router remotely.

Please help me on this matter. Appreciate your time

I interested to get DNS-726 also but looking at your problem make me think twice, have you upgrade the firmware to the latest 1.10 and what model of ip camera you using?

If you add a password to the camera's admin user and set the video stream to MJpeg this should not be an issue.

It is not as simple as that!!!

Having 4 diff. WL types D-link cams, I face exactly the same 3 problems and have also the same 3 questions as Shazlee69.

WXP pro sp3, (IE, GChroom, Maxthon, Safari) NVR726-4 v1.1,

Why not providing an internet port in the NVR-726 (similar as the cams  video,audio, rps and internet port)
which allows port 80, 8080 etc to be used elsewhere.

Hope to have a better guide provided, as I'm sure many other people struggle with these questions.

Thnks
