Model of your DVR?

Do you have access to IE browser?

What browser do you use?

In the local network everything is right?

Are you talking about local or remote access to the DVR?

When you will make redirect ports on the router you have to be login from public IP for example cam 1 - http://123.123.123.123:81 cam 2 - http://123.123.123.123:82

You have to change web port into the cameras, for example cam 1 - 192.168.1.100:81 cam 2 - 192.168.1.101:82 etc and those ports redirect on the router.

We don't know your cameras model. Please insert IP address of your cameras in "Compatibility View Settings" http://winaero.com/blog/how-to-enable-compatibility-view-in-internet-explorer-11-ie11/

First DVR can refresh IP address in DDNS account. Another may have disable this feature.

I propose IE11 but you have to make "Compatibility view settings". Just add your IP or domain address. http://winaero.com/blog/how-to-enable-compatibility-view-in-internet-explorer-11-ie11/

I think so. What kind of browser have you used?

Do you have redirected the appropriate ports for DVR 1 ? Have you checked access from internet? For example: http://IP_address:81

Those ports are to different applications or streaming. Please remind me models of DVR-s.

Ethernet standard doesn't support cable over 100 meters too. I propose optical or wireless connection between camera and "control room switch".

Ok, firstly we can configure DVR_1 and ports 81 and 8001 on your router in Port Forwarding tab. http://portforward.com/english/routers/port_forwarding/Dlink/DSL-2750U/Virtual_Skipper_3_+_4.htm

DDNS is needed when your public IP address is dynamic (variable). Please confirmation. IP addressing is still the same on DVR-s like in first post?

HiDDNS is only domaine name, you have to redirect port on your router.

Have you been redirected ports in Virtual Server tab? Can you show us it? IP addressing on your devices is all time same like in your first post? I had: 10.0.0.51 81 8001 554 10.0.0.52 82 8002 554 10.0.0.53 83 8003 554 10.0.0.54 84 8004 554

Yes it is WAN connection, there you can see IP address.

You have to check it in router STATUS tab. Static IP is must not always be public IP.

I understand that preview by local network is ok? Do you have public IP address on D-link router from your ISP? Yes you can preview by internet browser.

Your question was about video access by android, is that correct? I asked about local access by android or another devices (browser or dedicated software) is it possible?

Do you have local network access to DVR-s?
