may be it was my mistake and this is a wrong thread, sorry about it...
our product is not "classical" tracking system, it is other idea behind it - we have different zone's priority (1,2,3, "neutral" and "ignore"). If any intruder is detected in the more important area, the old target will be "dropped". It is possible to define intruder's properties - the physical size (we use 3D simulation inside), inactivity limit etc.
Thank you.
I hope to be able to public several really impressive demos during night operation in January - as soon our pre-production unit with high sensitive B/W panoramic cameras and special lenses inside will be ready...
Regards,
Alexander
