What universal program for IOS\Android to connect to noname DVR?

Question

CCTV

There is a noname DVR.
He looks at the LAN, the ports (80, 37777, 554) on the router are also forwarded, so that it would be possible to connect to it from a laptop and watch the room outside the office.
But this situation is not entirely satisfied, I want to watch from phones, anywhere where there is Internet.
The DVR is classic: a web-muzzle with activex, which is also installed only from a CD, there are no stickers, information on it was found on only one site, and there, apart from the dimensions in mm, the number of ports, there is no useful information.
So, what you can try to watch video from this registrar.
