Hello Dear All
Since on month I installed a CCTV System with DS-7216HGHI-F1\N in the beginning it's worked properly , but after tow weeks the DVR doesn't show any video at all channels !! , I tried Resetting it to inactive and update the firmware to solve the problem , but unfortunately still it's still gives me a black screen in all channels , just I would like you to inform me if it's hardware echo as i expected or it's about setting and configurations ....
