Digital Video Recorder

5. Why “Auto-overwrite” is invalid when recording is activated?

① Check whether the “Overwriting mode of recording” is “Auto cycle”; ② Check whether the HDD has logical error or

physical damage. If there is logical error, connect the HDD to PC and delete the partition information or repair the HHD

and connect it to the DVR. If there is physical damage, replace the HDD.

6. Why there is no response after click “Backup” when I use client software to backup DVR data?

Check whether firewall is enabled. The client software may not backup the DVR data if firewall is enabled.

7. Why the time skips when I play the recording files?

It is usually caused by the adjustment of time. To avoid this situation, please check whether the data need to be saved

before adjusting the time. If not, please format the HDD when the DVR is started after time is adjusted.

8. Why the image playing is slow?

① Check whether slow playing is enabled. The DVR supports 1/2, 1/4, 1/8 and 1/16 speed slow playing; ② Check whether

the HDD is connected properly and whether the HDD has bad sectors. The bad sectors of HDD may cause image

intermission or screen mess.
