OPERATING THE DVR
4.13. Backup
NDR-EA2104/NDR-EA2208 and NDR-EA2416 digital multiplexers provide a wide branch of methods
when it comes to copying the recordings.
User may copy recordings to external storage devices. The DVR features the possibility of copying the
recordings to an external HDD connected via the USB, or to copy the data onto Flash memories.
DVRs allow to copy the recordings in three available formats. Data format determines its later
playback and maximum file size. Following formats are available:
*.exe
- File size may not exceed 4 GB, both for FAT32 and NTFS. Number of channels that are
copied in the process is not restricted. The stored data may be played back on the PC with
Windows OS without installing additional software.
Note:
When copying *.exe files, FAT32 file system is recommended on the storage device. Using
NTFS-formatted storage device and exceeding maximum file size for that system (4GB) will
result in inability to playback the copied recordings as the copy process won’t stop after
exceeding max. file size.
*.strg
- Data are copied to *.strg format. File size may not exceed 4 GB for FAT 32 file system. In
case of NTFS file system, maximum file size is limited only to the NTFS maximum file size.
Maximum number of channels is also unrestricted. Data stored in this format may be played
back on PCs with E-Viewer installed, or by DVR.
*.mp4
- Data are copied to *.mp4 format. File size may not exceed 2 GB, both for FAT32 and NTFS.
Only one video channel is permitted during copy process. Recordings may be played back on
PCs with mp4-capable software installed.
Note:
Only FAT32 or NTFS file systems are supported on the storage devices.
Note:
When copying *.mp4 recordings maximum file size should not exceed 2GB.
