Q: Why does the NVR repeatedly print the Settings log "LocalRecord Parameters: Edit the record parameters of" even when no manual operation is performed?

A: In addition to recording user operations, the NVR also generates log entries for its own system activities. 

For example, when the scheduled recording parameters and event recording parameters for a channel do not match, a triggered event will cause the NVR to switch from scheduled recording to event recording, which modifies the parameters and logs the change. 

After the event ends, switching back from event recording to scheduled recording also modifies the parameters and generates a log. Therefore, if events such as motion detection occur frequently on a channel, these log entries will appear often.

In addition, the NVR may also generate such logs during NTP time synchronization, when an IPC goes offline or comes back online, or when the NVR Quickly Add an IPC.
