    Hi everyone I install a HCVR5108H-S2, now i want to connect a speaker to DVR, so i can talk to my worker on the field. I bought a 2.0 Speaker, it only have a 3.5mm jack, so i use a 3.5mm to RCA adapter like this one When i plug into the DVR, it arouse squeaking sound even i set the volume at 10%. I tested the speaker with my dvd player, it work flawlessly How can i resolve the problem

    I'm successful wired a 40meter rg6 cable. The quality's still very good. Thank you

    Using the outside network to ping the ddns address to ensure it's working fine. If the result is connection time out (it show the IP but can't tranfer data) then some ISP blocked NAT, you have to contract the ISP to tell them enable NAT service
