VCA is a real-time video analytics engine that utilizes advanced image processing algorithms to turn video into actionable intelligence. At the core of the product is an advanced object tracking engine that continually tracks moving and stationary targets. The tracking engine features built-in robustness to environmental nuisance conditions such as changing illumination, moving foliage, rippling water, etc.
VCA is a generic name for a suite of analytics products that include:
Enable the object speed rule on the selected zone by checking the Speed Filter box in the properties inspector. Adjust the lower and upper speed limits to suit the detection scenario.
Objects that travel within the bounds of the configured speeds, through a zone or over a line trigger the rule and raise an alarm.
Note: that the camera must be calibrated for this function to be available.
A counting line is a detection filter optimized for bi-directional object counting (e.g. people or vehicles) in busier detection scenarios. Examples of such applications may include:
The counting line filter is only enabled when the unit has been configured with a VCAretail license, and typically will generate a higher accuracy count than using the counters provided as part of VCAs.
Note: The maximum number of counting line filters that can be applied per video channel is 5.
Enable the counting line filter on a detection line in the desired direction(s) by checking the appropriate box in the properties inspector. An event is generated every time an object crosses the line in the selected direction. If multiple objects cross the line together, multiple corresponding events are generated. The events generated by the counting line can be tied to counters in the normal manner.
A counting line by itself simply generates events when an object to be counted is detected. In order to actually count the events, counters (one for each direction) can be created and configured to count the events generated by the line. To create counters,
