Are you sure ? I have this dongle part list from Geovision:
55-NG004-000 GV-NVR (GV) 4
55-NG008-000 GV-NVR (GV) 8
55-NG012-000 GV-NVR (GV) 12

55-NR002-000 GV-NVR 2
55-NR004-000 GV-NVR 4
55-NR006-000 GV-NVR 6
55-NR008-000 GV-NVR 8

Yep, I'm sure. You can setup a 16 cam full IP system but when setting
up a hybrid, 8 IP cams are maximum. Checked with Geo.
It sucks.

Post subject: How to protect delete files on DVR ?
|
You can lock the DVR with desktop but not that difficult to break.
So someone could delete recorded files.
With backup server you can instantly backup, but it recycle's.
So you will lose the files that are deleted after a while (even with a large disk).
Would be nice to have an option to never recycle deleted files on the backup server and have an alert mechanisme in place if files are deleted.
Protecting the recorded files is key but not really well implemented at the moment.
Any idea's ......

Do you mean the GeoVision Keylock utility?
How long do you wish to keep video files for?

yes I mean the Geovison Keylock.
The amount of time I want to keep the files is not that important (depends on the disk size).
But lets say it's a week and some event took place in that week and someone did delete the files.
You would not see anything and also would not know it took place (files are gone !). Even if you know something happenend you have to search all the files around that period and the backup to find evidence.
You could easily conclude it was not on camera and not even check the backup.
Even if they are backuped instantly there is no mechanisme to tell you that files have been deleted in an incorrect manner.

Could you PM me the details of how you can get around the Keylock, if this is the case, then it should be brought to GeoVision's attention.
If people have the correct permissions set up on their user accounts, then you shouldn't have any issues with people deleting files. (If Keylock is on, and they cannot access Windows Explorer)
All our systems are left running Keylock, so as far as I am aware, the user's cannot gain access to Windows to delete them through Explorer.
They can only delete them through the Viewlog then. All events deleted through the Viewlog are logged.

ok, rory was faster then I was ... and still other options possible, but you do need access to the system. If you can get it to restart without access then start windows in save mode ....

Agreed average users probably not, but simple things as a power failure with auto-boot setup will allow user to get into save-mode.
Even with a UPS it will restart after a while and Geovison does not detect it's on UPS power.
In high level security environments this could be an issue because it does not detect unauthorized changes on file-level.

Wonder if Geo could use True Crypt .. would be nice .. dont know about the speed though .. but you can create True Crypt volumes and format them as NTFS .. then when you reboot unless the user is logged into Geo, or if they yuck the hard drive out and try it in another computer .. they wont have access at all to the video no matter what they do .. without ofcourse the True Crypt login and a way to mount the volumes. Ofcourse a Windows user can also make their folders private .. but that doesnt effect the video files which are typically on another drive. I use true crypt in a program I wrote .. great free tool.

Even in Safe Mode you need to have access to the Token file, which is password protected.
With regards to having access to the system, and unplugging power etc. this is true for all DVRs. You cannot forget about physical security when dealing with a DVR system.
The systems we build are designed to always be powered on, set in the BIOS. If the power fails, and there is a UPS, the UPS battery will be used. As soon as power returns, then the unit will power back on (If the battery did not last through the disruption of power).
With Keylock used, and a reasonable level of physical security on a system (e.g. a locked room) then the system is secured.

Very simple solution, offer your customers the service of the vsm, then it will alert them if the DVR is off, someone has tampered with it, recording stopped, rebooted, etc..
