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.
