Hello,
I know this is not supported but…
I need a way to inject hardware into the SQL without actually opening the Management Client.
I imagine I could use some of the stored SQL procedures right?
Can you give me an example with an Axis camera?
This would really help me out 
There is two main reason why Milestone in general does not recommend directly modifying the SQL for the Milestone XProtect.
If you break the SQL you can render the whole VMS unusable.
If you find a way to modify the SQL it might work for one version but the database structure might be changed for the next version.
Nobody at Milestone attempted adding a hardware/camera . If there are Milestone partners that did this none of them have told me they were able to do it and make it work. It might prove impossible but I do not have that knowledge either.
