Motion Detection w/ Arecont Vision AV8185

The Problem: Motion detection does not work for the Arecont Vision AV8185 SurroundVideo 180° camera.

Historically Nx Witness does not do server-side motion detection analysis for Arecont Vision SurroundVideo series cameras. Given the large size of the stream and the inability of the cameras (again, historically) to provide dual streams from each sensor (which is required for Nx Witness' server-side motion analysis and search) Nx Witness has used camera-side motion detection and periodic Arecont API calls to request motion data from Arecont Vision SurroundVideo cameras. 

After some recent firmware updates specifically for the AV8185 some users may have noticed they no longer have motion search and analysis on the AV8185. 

The Solution: Use an AV8185 with one of the following firmware versions

Download and install one of the following firmware packages from the Arecont Vision website to fix the issue: 65191 or 65166. We can confirm it still works properly with these versions.
