Hi, I have a problem here, our DVR suddenly stopped recording and when i checked, HDD was not detected, then when I opened the HDD on my PC i see different DAT FILES. is there a way that i can view the dat files to see the footages in the HDD? Carlo Joseph O. Alejandro

Hi, We have used CAT 5 UTP cable for our CCTV cameras, but instead of placing video baluns, we directly connected it to a male BNC connector no both sides, now when we connected it to the DVR the video output seems to be grounded. is it the cable or should we use a video balun?
