Select the “Performance” tab; check the status of the CPU and Memory.
If the resource is not enough, please end some unnecessary processes.
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 manufacturer 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:
a) Cable between the pickup and IPC is not connected well; impedance mismatches or incompatible.
b) The stream type is not set as “Video & Audio”.
c) The encoding standard is not supported with NVR.
Steps:
1. Verify the cable between the pickup and IPC is connected well; impedance matches and compatible.
Log in the IPC directly, and turn the audio on, check if the sound is normal. If not, please contact the
manufacturer of the IPC.
2. Verify the setting parameters are correct.
Select “Menu > Record > Parameters > Record”, and set the Stream Type as “Audio & Video”.
3. Verify the audio encoding standard of the IPC 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 IPC to configure it to the supported standard.
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 manufacturer 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 IPC, and there exists packet loss during the transmission.
b) The motion detection and alarm functions are enabled, and the parameters of Main Stream (Normal) and Main
Stream (Event) are different. So the image looks stuck due to the image changes between different resolutions.
c) The frame rate is not the real-time frame rate.
d) 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
hesitation.
Steps:
1. Verify the network between NVR and IPC is connected.
1) When image is stuck, connect the LAN port on a PC and the rear panel of NVR with an RJ45 LAN cable.
2) Go to the COMMAND screen (Start -> Run -> CMD -> Enter), and execute the ping command, 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.
Note: Simultaneously press the Ctrl and C to exit the ping command.
2. Check the parameters of Main Stream (Normal) and Main Stream (Event).
Select “Menu > Record > Parameters > Record”, and set the resolution of Main Stream (Event) the same as the
one of Main Stream (Normal).
