Cross line detection 
This function can be used to detect people, vehicles and objects crossing a pre-defined 
line or an area on-screen. The line crossing direction can be set as unidirectional or 
bidirectional. Unidirectional is crossing the line from left to right or from right to left. 
Bidirectional is crossing the line from both directions. 
A series of linkage methods can be triggered if an object is detected crossing the line. 
Dual-VCA (Video Content Analysis) 
When Dual-VCA mode is enabled, the camera sends video analytics results (meta data) 
to an NVR or other platforms to generate a VCA alarm.   
For example, with an Interlogix NVR (please check Interlogix website for the latest NVR 
models supporting this feature), you can draw a virtual line in the NVR playback 
window, and search the objects or people crossing this virtual line. 
Note: Only cross line and intrusion detection can support dual-VCA mode.
