This plug-in provides a professional detection module for iSpy, designed to detect, track and classify any significant object entering large monitored areas. Just set some rules (minimum distance to cross, or object's lifetime) and virtual fences to trigger an alert. It is much more powerful than classic motion detection!
You can now detect intrusions in large areas, even if intruders are only a few pixels tall.
