Hello, I have the Dahua VTO2202f-p with the VTH monitor - both hooked up to a POE switch. IP adresses 192.168.1.110 and 109. The setup works flawlessly without the router connected. As soon as I connect the router to the switch (same network) I loose the video connection on the vth and the router changed the sip server ip adress. Has anybody a solution for me ?
