The value set in the LILIN Navigator software 'Circular Record' option is the amount of hard disk drive space LILIN Navigator will NOT use on the selected recording destination HDD.
(This value can be set independently per destination HDD within the LILIN Navigator software 'System Settings')
In the example above the Circular Record value is set to 6GB. This means Navigator will leave 6GB of HDD space on the selected D: drive before recycling its recording through the HDD.
So as an example, if you have a 2TB HDD and only want to assign half of it for CCTV recordings, rather than partition the disk in 2 halves you can simply set the Navigator Circular Record value to 1000GB. This will allow the Navigator software to only use approximately half of your HDD. This value can be adjusted at any point.
We do not recommend setting the Circular Record value lower than the original default value set by the LILIN Navigator software. Windows requires a certain amount of available HDD space for hidden, system and temporary files, setting this value too low may result in Windows OS problems or other issues.
