Chapter 3. VIDEO STREAMING AND CHANNEL SETTING

In addition to the types of license, there are some attributes associated with a specific license. Depending

on actual business terms, a license might have a number of following properties:

 Forced online license: If a license has this attribute, it cannot be committed to computer. If you try

to do that, it will fail (Offline Install Forbidden). This is needed in some business terms to enforce

certain licensing policies.

 Limited (Expire able) license: A license may subject to expire after certain date (either demo

license or not). This kind of license implies "forced online license".

 Demo/Evaluation: If a license has this attribute, the program will display an evaluation notice

stating that "using the software in production environment of any kind is strictly prohibited". This

is needed for customers who want to try the software before paying. The function of the program

is, however, almost same as the formal one. Demo version implies "forced online license" and

"limited license" (the reverse is not true). A demo license can be transparently converted to

formal one by paying fees to clear the demo flag on the server. The user only needs to restart the

NVR engine to obtain formal license automatically.
