| Analytics+ Functions | ||
| Face Detection | • Detects and captures a snapshot of a human face in a defined area within a scene. | |
| Smart Motion Detection+ | • Differentiates between and classifies human and vehicle objects. • Filters false alarms due to leaves, lights, animals, and other inconsequential objects. • Extracts human or vehicle objects from recorded video for quick target search and retrieval. | |
| Perimeter Protection | • Detects human 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. | |
| Predictive Focus Algorithm (PFA) Technology | • Uses statistical analysis to stabilize the scene to preserve clarity when zooming • Performs real-time analysis and adjustment of subject distance for a rapid and stable transition from different subject distances . |
| Intelligent Video System (IVS) 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. |
| Premium Features | |
| Tripwire | A target crosses a user-defined line. |
| Intrusion | A target enters or exits a defined perimeter. |
| Abandoned/Missing Object | A target leaves an object in designated area, or a target removes an object from the same designated area. |
| Advanced Features | |
| Loitering Detection | Target is in motion inside a defined area longer than a specified amount of time. |
| 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. |
| Human/Vehicle Classification | Detects human or vehicle violations using Tripwire or Intrusion detection methods. |
| Auto-tracking | Controls the pan/tilt/zoom actions of the camera to automatically track an object in motion and to keep it in the scene. |
