Our VMS Search Shootout showed that performance varies greatly and is an important differentiator in product selection.
One uncommon but interesting feature is the ability to overlay people and vehicles from different times on a single video to quickly show who and what passed by in a scene. Axxon's VMS has this, calling it Time Compressor. Here's their very short demo:
It's free and built into their VMS, so we decided to test it to better understand how well it performed.
For indoor scene there is a possibility to adjust min and max size ofobject to get proper result similar to outdoor scene.
And AxxonSoft has patented this method because it is different from other existing technologies.
Also important to say, that we are doing it based on typical metadata, generated by our own analytics engine or received fromcamera. In v4.0 we'll support Bosch, Panasonic, Sony and ONVIF scene description metadata streams to implement TimeCompressor.
