Login to DVR using TCP socket

Question

I want to create a client for myself to connect and show my DVR stream.

I have sniffed the traffic on an android device when a working client app makes a TCP connection and all it seems to send to the DVR is H( )8admin1 and then the data comes along. (admin and 1 are login credentials)

I have tried to do the same with a socket tester app in android and also on windows just to try to get the data coming but even though I send the same string to the DVR it doesn't start sending packets as it does when other client apps send the same string. I see in wireshark that an ACK packet is received in response to sending the string.

Can anybody point out what I might be doing wrong please or something else to try?

Thanks

Peter
