Verify the setting parameters are correct.
Select “Menu > Record > Parameters > Record”, and set the Stream Type as
“Audio & Video”.
Verify the audio encoding standard of the IP camera is supported by the NVR.
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 NVR is playing back by single or multi-channel.
Possible Reasons:
a)
Poor network between NVR and IP camera, and there exists packet loss during
the transmission.
b)
The frame rate is not the real-time frame rate.
c)
The NVR supports up to 16-channel synchronize playback at the resolution of
4CIF, if you want a 16-channel synchronize playback at the resolution of 720p,
the frame extracting may occur, which leads to a slight stuck.
Verify the network between NVR and IP camera is connected.
1)
When image is stuck, connect the RS-232 ports on PC and the rear panel of NVR with
the RS-232 cable.
2)
Open the Super Terminal, and execute the command of “ping 192.168.0.0
–l 1472 –f” (the IP address may change according to the real condition),
and check if there exists packet loss.
Simultaneously press the Ctrl and C to exit the ping command.
Verify the frame rate is real-time frame rate.
Select “Menu > Record > Parameters > Record”, and set the Frame Rate to “Full
Frame”.
Verify the hardware can afford the playback.
Reduce the channel number of playback.
Select “Menu > Record > Encoding > Record”, and set the resolution and bitrate
to a lower level.
