- Recognition enhancements
- Yes, depending on the size of the vehicles: low, medium, normal, high, ultra, insane
- Recognition speed
- Less than 200 ms/frame at high settings, using an appropriate GPU
- Number of recognized people or vehicles in each frame
- Unlimited
- Number of defined counting gates
- Unlimited
- Direction of movement for each object
- Yes
- Object dimensions
- Yes, if appropriate GPS coordinates are properly configured
- Trigger type
- Over UDP from a Metrici Multicontroller, a Barix Barionet 50 LAN controller, from the Metrici LC web interface, or from another Metrici engine (LPR, CCR, QR, etc.)
- Companion stream
- Yes
- Live view
- Yes, 1 fps
- Data type for each counted person or vehicle
