A list of already-executed download tasks will appear on this screen.
All the download tasks will be programmed from the Scheduling menu option (see previous section).
The list of downloaded video appears in the working area. Each video has a brief description on the status field,
showing the downloaded video content.
In a schedule with more than one camera, if any of its cameras has no video in the period, the camera won’t
appear in the list.
It is possible as well to see that there is “no video found” for a specific download (see example). This happens
when trying to download video from a period where there’s no video recorded.
Once you select one download from the list (double click) at the bottom part of the screen you will see the
download detail. The list will show all the different downloaded cameras and the start and the end date of the
video. At the top of the list, you will see the total size of the download. This data is important in order to know
the disk space needed.
You can also export the downloaded video to disk or any removable device through the “Export…” button. Set an
export password in order to restrict hash checking.
Also you can burn a CD or DVD disk with the content of the download and erase the destination before burning
it.
Double click on any camera record to watch its video. The media player used depends on the download
parameters. If it’s a dvr download and the option “Native format” was checked, then a specific video player for
that format will be used. Otherwise, the default media player installed on that PC will be used.
3.8.1 Digital Signature
Any downloaded video content will include a security control that ensures that the exported evidence is the
original one without any kind of manipulation. It is not possible to modify an exported video in any way. A Digital
signature file will be used to verify this fact.
On the other hand, to increase the security of the exported video you can also protect it with a password. This
password will be used to certify the video content. There is no any other way to certify that the video is correct if
the operator does not know the password.
