What is the difference between intrusion detection and line crossing detection?

Intrusion detection and line crossing detection are two distinct AI functionalities used in Viewtron AI security cameras. Here’s the difference between them:

Intrusion Detection

• Detection Area: Uses a polygon-shaped zone to define the area of interest.
• Trigger Mechanism: An alarm is triggered when a human or vehicle enters or exits the defined intrusion zone at any location.
• Use Case: Suitable for monitoring a specific area where any entry or exit is considered a security event.

Line Crossing Detection

• Detection Area: Involves drawing one or more virtual tripwires (lines) on the scene being monitored.
• Trigger Mechanism: An alarm is triggered when a human or vehicle crosses the line in a specified direction (e.g., A->B, B->A, or both directions A<->B).
• Use Case: Ideal for monitoring specific entry or exit points, such as a parking lot entrance or a walkway, where crossing a line in a particular direction is significant.

Both methods can be applied to human detection and vehicle detection. And both can trigger alarms, video recording, push notifications, and other actions, but the key difference lies in how the detection area is defined and the type of movement being monitored.
