1. On web (ERR=-1) - when the system log has no data the search result displays an error message. What error code and can it be removed?

Local side (NO LOGS):

2. Very important - How are system logs stored? Are they stored the same as the recording data? If the HDD is set to overwrite the recording data. Will the system logs be overwritten as well? The system logs should be available and stored longer than recording data. So the log can be checked for previous problems.
