I also am having the same problem. I have a H.264 Stand-alone DVD 8CH.
I have reset the DVD to factory but can’t see how to set the DVD to record. The DVD has been working previously
i have no record light lit up on the dvd
i have searched for files but shows no files
Dates are correct as of today
the playback page shows all cameras as black with the word STOP at the top this of the screen
Record has been set at 15mins packet time.
yes I do have a DVD as previously I was able to view recordings
Schedule has been set as ALWAYS
i have tried an emergency record as a way of testing but nothing
hope you can help
