What is the difference between Evidence Library Express (ELX) and Evidence Library Express Viewer (ELX Viewer)?
As part of the import process, ELX will put a Mark for Deletion file back onto the USB flash drive or VISTA. This tells the device (4RE or VISTA) that those events have been successfully imported into the library and that it is safe to delete them from the device. ELX Viewer does NOT put a Mark for Deletion file on the USB flash drive or VISTA camera, so those events are not removed from the device.
All other features/functionality are the same for ELX Viewer as for ELX.
NOTE: ELX Viewer can be used in conjunction with Evidence Library (if configured), however ELX cannot be used with Evidence Library.
