Pelco-P/D (Auto recognition) |
| IVS (Perimeter Protection) |
Tripwire; intrusion; crossing fence detection; loitering detection; abandoned/missing object; fast moving; parking detection; people gathering; vehicle/human alarm classification; linkage tracking |
| Face Detection |
Supports face detection, capturing snapshots, uploading face snapshots, enhancing face images, and selecting a preferred image among a group of snapshots. Attribute extraction is also supported. |
| SMD |
SMD 3.0 |
| Auto Patrol |
It triggers the IVS rule when a target is detected and makes the camera link with the PTZ to rotate to the position of the target and patrol based on its presets. |
