After plugin multimedia centrum to LAN, DVR recorder stop working

Question

I just upgrade my home LAN with multimedia player Xtreamer SideWinder3 , but after I connect Xtreamer to my local net, I see that my home security system is down every time I just start to play a movie or some other multimedia.

Security system works on DVR recorder and this recorder is plugged to my LAN only for HTTP login to see real video from cameras over the browser. All signal from cameras comes to DVR directly with cable not over LAN. The HTTP works on port 80 as usual, I just changed this port to 81. No DHCP functions are in DVR.

Xtreamer is working on port 80 as usual, just for configuration over the browser.

I changed the ports on DVR recorder, because I thought that this could be the problem, but after change nothing happen.

LAN configuration: - Router gives address 192.168.1.xxx - All address are reserved in router via MAC address

Thank you Jan

Answer 1

After one week analyzing all possibilities why this is not working I found that the IR remote control of multimedia works on the same frequency as DVR. Every time I used remote control for multimedia I turn off the DVR by pressing one sequence of command.
