Joe, can you clarify? Exacq does not support server side VMD, even if you run Exacq on the camera, I believe you need to use Axis' VMD options. We have tested VMD3 and it is much better than Axis legacy VMD (see: Axis VMD3.0 Analytics Vs Avigilon Tested).
With ExacqVision Edge running on the camera, it allows you to set up some motion windows. The only settings are Sensitivity and Percentage. One example says to reduce the Sensitivity to reduce false positives from a swaying tree or to increase the Percentage to reduce false positives from leaves blowing across the scene. I guess I was really asking if this was using the camera's standard motion detection(pixel change) or some level of intelligent analytics.
In my application, I need to detect a person from a long distance using a thermal camera so the Sensitivity would likely need to be high and the Percentage low. I believe this configuration will produce lots of false positives if it is truly based on pixel-change.
I can also run VMD3 cocurrent to the Edge application but was am looking for feedback from anyone who has used ExacqVision's motion detection. Specifically, if it is any better than standard pixel-change based detection.
I am the product manager for exacqVision. John is correct. When you configure motion detection within exacqVision, we are passing those configuration settings to the camera, as exacqVision does not have a motion detection feature built into the server.
Since we never have to decode and analyze video on the server, that is is how we keep the server very efficient and able to run on cameras and other low power computers.
VMD3 support is planned for our December 15 release. We are enhancing our native Vapix handler to handle the metadata from VMD3.
