Que:- i would like to ask if any one of you is familiar with these Linux based units
is there a way if i change these ports that the DVR gonna be accessible?
Ans:- First of all you have to write all ports and change the http port and rtsp port and server port .
e.g: if your configuration for IP 192.168.1.10 Http port will be 81, you have to type 192.168.1.10:81 to access the dvr respectively you have to change the rest dvr port number.
