Digital Video Recorder

(III) Video recording/playing, recording data, backup

1. Why the recording has no audio?

① Check whether “Mute” is activated; ② Check whether “Audio” is selected in the settings of video recording; ③ Check

the audio input cable.

2. Why I can’t perform timing recording or can’t record any data within the period?

① The period of timing recording is invalid. The time points should be within 00:00-24:00 and the end time must be later

than the beginning time; ② The power supply is cut off in the timing recording process; ③ The desired data have been

overwritten; ④ The HDD has physical damage or logical error and the data can’t be read normally.

3. Why I can’t perform moving recording or alarm recording?

① The time period of moving recording or alarm recording is invalid. The end time must be later than the beginning time;

② No motion detection area is selected; no alarm recording channel is selected; ③ The sensitivity of motion detection is

too low; the alarm isn’t triggered correctly; please check the alarm input and triggering device.

4. Why the recording isn’t continuous?

① If manual recording or timing recording is selected, check whether the power supply was cut off or voltage was

abnormal during the recording process; ② If motion detection recording or alarm recording is selected, check whether

alarm occurred. The alarm will trigger the recording and record according to the preset time.
