Newer iPIMS Version 184.108.40.206 supports newer and older series of HD-Express ( newer HD express 4L3...8L3 / Older series non L3 )
When adding New Device from the drop down select " NVR " as the model ( not H.264 DVR)
This will be replacing older version iPIMS V220.127.116.11 (July 2014) will not work with new HD Express units.
An error under “Device State” - “Model Mismatched.” would occur when attempting to add newer NVR to older iPIMS.
Vicon's Web Site should be updated soon with newest version.
