Recording to archive is performed on a loop in the Intellect software package (see the General information on video archiving section). Therefore, old archive recordings can be replaced by new ones. But sometime it is required to protect important recordings against loop recording. In such case rights for protecting files against rewriting are needed.

Protected files are moved to the PROTECTED folder in the VIDEO folder on the disk with archive. When the file is deprotected it is moved back to folder from which it was taken if it exists. If this folder was removed because of all files in it were rewrote, then file will stay in the PROTECTED folder but won't display in the Monitor. Later this file will be deleted by loop recording. При снятии защиты с защищенного файла он помещается обратно в папку, из которой был взят, если она еще существует. Если же папка уже была удалена, так как все файлы в ней были перезаписаны, файл остается в папке PROTECTED, но не отображается в Мониторе видеонаблюдения. Позднее такой файл удаляется в процессе записи по кольцу.

To issue permissions for rewrite protecting of archive files, do the following:

1. Go to the Users tab in the System settings dialog box (1).
   
2. In the objects tree located under the User permissions button in the Users tab select the same-name object corresponding to the Operator access permissions which are to be changed (2).
3. The settings panel of the User permissions object will display on the right of the System settings dialog box.
4. To allow Operator to protect archive files against rewriting, set the Allow rewrite protection checkbox checked (3). Don't set this checkbox checked if the operator should not have this permission.
5. To allow Operator to disable protection of files protected against rewriting set the Allow to disable file protection checkbox checked (4). Don't set this checkbox checked if the operator should not have this permission.
6. To allow Operator to export protected files, set the Allow export checkbox checked (5). Don't set this checkbox if the operator should not have this permission.
7. Click the Apply button.

Permissions for the Operator to protect archive files against rewriting are now set.
