How to Enable Audio for an IP Camera Using an NVR 
Due to specific regulations most IP cameras sold by Amcrest that feature a built-in microphone will have 
the microphone disabled by default. These options however can be enabled manually by using the IP 
camera's and NVR's web user interfaces (web UIs) using a common web browser. For more information 
on how to enable audio for an IP camera using an NVR, please refer to the information provided below.  
Log into your NVR's web UI using a web browser and ensure that the IP camera is properly registered to 
your NVR. Once the camera is confirmed to be registered properly, locate the Web Browser column, 
and click on the "e" icon to load the web UI for your camera.
