BVMS Lite and BVMS Viewer are BVMS editions that you can download and activate free-of-charge.
How can I set-up a basic (live and recorded video) BVMS system?
First, you need to download the software package, active the BVMS Lite license and install the software. This is described in this article: BVMS - Activating a license.
Second, you need to prepare an iSCSI environment which is suitable for recording video. Any Windows Server based operating system will do. This is described in this article: BVMS - Configuring a Microsoft iSCSI target.
Last, you need to add cameras to the system and start the recording. This is described in this youtube video: How to add a new camera using Configuration Client (BVMS).
Now, have a look at the Operator Client quick guide and you're ready to go!
Once the software (configuration client or operator client) is running you can press F1 at any time to open the embedded software help! All of the advanced functionality BVMS offers is explained in the help files.
