To configure recording to the an archive for one camera, do the following:

  1. Go to the Archive tab.
  2. Select the created archive.

  23. In the Depth, days field

    24. (3)

  24. , specify the maximum archive depth of the given camera in days. If you set the 0 value

    25. is set

  25. ,

    26. the

  26. archive depth is unlimited. As a result, the archive will only contain recordings within the specified depth. The recordings that are outside of the specified archive depth

    27. won’t be available

  27. are unavailable for viewing. 

    Note
    titleAttention!
    • If you set an unlimited archive depth for one or several cameras, at some point the archive
    28. will become

    • . Therefore, if you set an unlimited archive depth for at least one camera, limiting the archive depth for other cameras is unnecessary.
    • When you configure the archive depth for each camera, we recommend calculating the storage

    • situations when
    33. the
    • an archive is stored for fewer days than specified.
    • When you specify the archive depth for a particular camera, note that the priority of the total archive depth is higher (see Configuring access restrictions to an archive). If the archive depth of a camera is 20 days
    34. ,
    • and the total archive depth is 10 days, the archive depth of a camera won't exceed 10 days.
    • Later, if you change the available archive depth of a camera upwards or to 0, the setting will apply only to new recordings. Earlier recordings outside the initial archive depth don't become available.

  35. In the Prerecord, sec
