Why is my NVR making a loud beeping noise?


The beeping noise that you are hearing can be one of several issues. To determine what is the cause access the main menu of the NVR and go to Maintenance > Log. Change the 'Major Type' to 'Exception' and keep the Start and End Date as default and select 'Search'

The results will give the reason for the audible warning. You can either disable the warning or troubleshoot the issue.
