For those of you looking for motion detection with your cameras, I implemented something that works pretty well for me.
I installed the Milestone XProtect NVR software (free for 8 cameras), and set it to email on motion detected. Then I wrote an email server binding for openhab so all the traffic stays local to my network. So far it is working great. All my cameras are not centralized and controlled in a great NVR system, which also centralizes all my motion detection configuration to ship it off to openhab.
If you are interested in the binding, comment here:
