Hello, I am new here. I hope I can get some information and maybe solution about my DVR setup for my office.
First of all, here's brief information about the setup :
1) I have around 11 branch, all of them using same DVR (Chinese DVR, the brand is "Haven" I think)
2) I have properly setup the network configuration within their own local network and I can access it well
3) I already setup port forwarding on router (Some using Mikrotik and some using TP-Link ADSL modem with NAT-capability)
4) For each branch, I already setup a public domain and DDNS so I could access them each time their IP changed
Here comes the problem :
1) Since all of them came from same brand, they used same DVR-CMS software. The problem occur when I tried to connect to some DVR using their mediaport via DVR-CMS (e.g: http://something.mydomain.com:49999) and it said "Registration failed"
Note 1: It only occur to some DVR, some other DVR within another branch work correctly
Note 2: It only happened when I try to connect via Media port. I connect to Mobile port (lets say the port is 6900) via Android phone/tablet using MEye program and it connected
2) I try to examine further by connecting via web port (e.g: http://something.mydomain.com:8000). It can connect and display login box. But when I try to connect via that login box (using media port or 49999), it stated "Network Error"
Note 1: When I try to login via web port from LAN (e.g: http://192.168.1.1:8000), it shows login box and I can connect (via media port or 49999)
So to sum it up,
Same DVR, same software, some can connect via media port, some can't. Mobile port working correctly
Any info on this?
Sorry for my bad English
Additional note :
For DVR's I can't connect, I tried to telnet them, and I got proper response (screen with KTSY message)
So I think the problem lies in DVR-CMS software, but as many other Chinese app/hardware, this thing lack of documentation
