Hi John,

NEXCOM new mobile ip camera built-in EIS, please see the testing video :

NCm-301 video stablization - YouTube

The left side image is with EIS, so the image is more stable.

I think this link is a good example of what this article points out. The test platform is producing a fixed frequency vibration of constant amplitude. The best case senario. Would like to see a demo of the systems performance under dynamic conditions which you would have in the real world.
