Hello to everybody! We have installed one year ago a Dahua NVR -128 channels- line 6000.
After this time appered this this problem: if you playback video continuously through, for instance, half an hour, there is no problem but if you "jump" the time (always directly in the NVR) the camera show nothing at all.
For example, the equipment records a camera from 11:00 to 11:30. If you see the playback continuously: no problem at all, all the video was recorded, but if you apply the cursor to 11:12 hour and try to see the playback, the cursor jumps "automatically" to 11:32. This is happening randomly in every channel and in every camera. It is the same effect if nothing was recorded but, I repeat: you can see continuously in playback without interruption correctly.
I´ve installed 40 PTZ Dahua domes onto this NVR. It functioned without any problem till now: firmware and software actualized, but the failure persists. Any idea?
Thank you! and sorry for my english :) Juan.
