Select “Menu > Record > Parameters > Record”, and set the Frame rate to Full Frame.
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 device 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 camera 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 device.
Steps:
1. Verify the cable between the pickup and camera is connected well; impedance matches and compatible.
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 camera is supported by the HDVR.
HDVR 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 company to do the further process.

The image gets stuck when HDVR is playing back by single or multi-channel IPC.
Possible Reasons:
a) Poor network between HDVR and IPC, and there exists packet loss during the transmission.
b) The frame rate is not the real-time frame rate.
c) The HDVR 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.
Steps:
1. Verify the network between HDVR and IPC is connected.
1) When image is stuck, connect the RS-232 ports on PC and the rear panel of HDVR 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.
Note: Simultaneously press the Ctrl and C to exit the ping command.
2. Verify the frame rate is real-time frame rate.
Select “Menu > Record > Parameters > Record”, and set the Frame Rate to “Full Frame”.
3. 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.
4. Reduce the number of local playback channel.
Select “Menu > Playback”, and uncheck the checkbox of unnecessary channels.
5. 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.
