| Analytics+ Functions² | |
| Smart Plan Schedule | Enable Analytics+ functions depending on a user-defined schedule. Allows the camera to switch analytic functions based on time. |
| Perimeter Protection | • Detects human or vehicle violations using the following methods: Tripwire: a target crosses a defined line. Intrusion: a target enters or exits a defined perimeter. • Monitors a combination of detection methods. • Search and retrieve video based on target type. |
| People Counting | • Delivers accurate flow statistics from the following methods: Line Crossing: counts a person as they cross a threshold in a defined direction. Region: counts the number of people in a defined area. • Counts people simultaneously from four (4) threshold lines and four (4) defined regions. |
Intelligent Video System Functions
| IVS triggers an alarm and takes a defined action for the following events: | |
| Standard Features | • Tampering with the camera. • Error writing to an onboard Micro SD card. • Error sending or receiving data over the network. • Unauthorized access to the camera. • IP Address Conflict |
| Premium Features | |
| Missing Object | An object is missing from a designated area. |
| Abandoned Object | An object is placed in a designated area where no object should be. |
| Scene Change | A person or object moves the camera to change the scene or covers the camera to obscure the scene. |
| Fast Moving | Target exceeds a set speed when exiting a defined area |
| Parking Detection | Vehicle remains in a defined area without motion for a set period of time. |
| Crowd Gathering | Specified number of people remain inside a defined area for a set time. |
| Loitering Detection | Target is in motion inside a defined area longer than a specified amount of time. |
