I had been looking for a good software for my home network security camera and found VTM-D...i like it pretty much so far after using the demo version about 48 hours. But I just suspected very strange situation of VTM-D.
Yesterday around noon I remoted back home from work to check on my VTM-D application and reviewed all results from last 3 hours and there were at least 54 results at the time. But after I returned home from work I found all the last 54 results that I viewed during my lunch time were completely gone and it was replaced by new results which created an hour ago before I get home after 8 hours working shift.
Today it just happened the same thing. All the images were created as search results at noon were deleted automatically after a certain of hours. ..very strange...I have tried many ways to recover all previous results with no succeed. Regardless of all functions have been double checked and no ones has access to my network security but me....the workstation is locked and secured by many layers of different passwords. Does Anyone have been experienced like this situation before ? please give me some feedbacks on this .
All activity results were completely gone!!!

Re: All activity results were completely gone!!!
I would guess that you are running out of disk space to store video. Or you might have possibly set the amount of space to use to a very small amount. When VDV runs out of disk space to save raw video, it automatically deletes the oldest video to make room for more.
Click on the "Tools" menu and select "Options". At the bottom of the dialog box that appears will be a line showing how much disk space is available on the disk. At the top will be a text box showing how much space that VDV will use of the available space. if the drive has more room, change the value in the text box a the top to a larger number. You can set it to use all the available space, but if the computer is also used for other things you might want to leave room for those other things.
Depending on the camera resolution, color depth, complexity of the scene and amount of motion in the scene, a 1 minute video can require anywhere from 250-Kb (or less) to 4-Gb (or more) of disk space. Thus the default (I think) setting in VDV of 25-Gb for storing Clips and Temporary Video may be a only 4 or 5 hours.
If your computer has only one drive you will be limited to what is available on that drive. You can increase the available space by deleting all the unused data and programs on the drive. Cleaning a disk drive of unused/seldom used data and programs can be a heart wrenching job that most of us try to avoid, but may provide you with enough disk space. Copy those family photos that you haven't looked at in years to a CD or other mass storage media and delete them. Delete programs that came with the computer but you have never run. I have cleaned up disks for other people (for other reasons) and recovered nearly 3/4 of the total disk space by deleting the games, trial software and other "extras" that many computer vendors put on a new computer for the user's convenience, but the user never used, didn't want or never even knew were there. I recommend defragging the drive after cleaning it. Depending on the program used to do the defragging I recommend doing it multiple times (many of the defrag programs only make one pass at the drive and if there is no room to consolidate a file in one contiguous space it will skip that one and go on to the next, but consolidations of later files can then make room for the one that was skipped, so a 2nd (or 3rd, 4th or 9th) pass might consolidate the drive more. I think that VDV works better if the database files have plenty of contiguous space to expand into without fragmenting.
Of you can add another drive to the computer just for the video data, the Options dialog also has a button ("Move Video...") that will allow you to change which drive the data is to be stored.

Re: All activity results were completely gone!!!
Thank you so much Semper Vaporo!!! you actually did pointing out the problem caused. I did not realize my pc were running out of space because of too many junk applications were installed on its. Now I just formated the pc today and install a fresh OS with only VTM-D was installed beside. I got plenty of space now and the pc may keep up running all day long. Awsome!!!
