4.
Check if the fault is solved by the above steps.
If it is solved, finish the process.
If not, please contact the engineer from our company to do the further process.
When using the NVR to get the <Live View> audio, there is no sound or there is too much noise or the
volume is too low.
Possible Reasons:
−
The cable between the pickup and the IP Camera is not connected well; impedance mismatches or
incompatible.
−
The Stream Type> is not set as <Video & Audio>.
−
The encoding standard is not supported with the NVR.
1.
Verify the cable between the pickup and IP Camera is connected well; impedance matches and
compatible.
Log in the IP Camera directly, and turn the audio on, check if the sound is normal. If not, please
contact the manufacturer of the IP Camera.
2.
Verify the setting parameters are correct.
Select “Menu > Record > Parameters > Record”, and set the Stream Type as “Audio & Video”.
3.
Verify that the audio encoding standard of the IP Camera is supported by the NVR.
The NVR supports G722.1 and G711 standards, and if the encoding parameter of the input audio is
not one of the previous two standards, you can log in the IP Camera to configure it to the
supported standard.

Check if the fault is solved by the above steps.
If it is solved, finish the process.
If not, please contact the engineer from our company to do the further process.
The image gets stuck when the NVR is playing back by <Single> or <Multi-channel>.
Possible Reasons:
−
Poor network between the NVR and the IP Camera, and there exists <Packet Loss> during the
transmission.
−
The <Frame Rate> is not the <Real-time> <Frame Rate>.
−
The NVR supports up to <16-channel Synchronized Playback> at the resolution of <4CIF>, if you want
a <16-channel Synchronized Playback> at the resolution of <720p>, the frame extracting may occur,
which leads to a slight stuck.
1.
Verify that the network between the NVR and the IP Camera is connected.
1)
When the image is stuck, connect the <RS-232 Ports> on the PC and the rear panel of the NVR
with the <RS-232> cable.
